Rocinha, Rio De Janeiro, Brazil 250 000 Paracity on Suomalainen keksintö ja vientituote, joka yhdistää puurak- entamista ja ympäristöteknologiaa ennennäkemättömällä tavalla. Kau- punkirakenteen CLT-massiivipuurun- ko valmistetaan ja viimeistellään Suomessa. Rakenteella on erino- maiset maanjäristyksen- ja palonkesto-ominaisuudet. Tapaus- kohtaisesti valittava modulaarinen ympäristöteknologia mahdollistaa kau- punkirakenteen itsenäisen kasvun ja toiminnan ympäröivän kaupungin infrastruktuurista riippumatta. Paracity soveltuu katastrofialueiden jälleenrakennukseen, slummien kunt- outukseen, tulvatasangoille ja tsuna- miriskialueille rakentamiseen, sekä kaikkeen muuhun asuin- ja yhdyskun- tarakentamiseen. Kaupunkirakenteen pystyttäminen on nopeaa korkeasta esivalmistusasteesta johtuen. Kaikki käytettäväpuuonekologisestisertifioitua. Ensimmäisen sukupolven kapunki on rakennettu ihmisyhteisö, joka elää välit- tömässä vuorovaikutuksessa luonnon kanssa ja on ympäröivästä luonnos- ta riippuvainen. Taipein hedelmällinen tulvatasanko on tarjonnut puitteet tii- viille asutukselle, joki on tuottanut ruo- kaa ja väylän liikkumiselle ja tasankoa ympäröivät vuoret ovat suojanneet kaupunkia taifuunien suorilta iskuilta. Toisen sukupolven kaupunki on teol- linen kaupunki, joka elää näennäises- ti itsenäisenä luonnosta. Itse asiassa luonto toimii haitallisesti mekaaniselle koneelle, esimerkiksi tulvat tuntuvat haluavan hajottaa koneen. Taipei on ra- kentanut kaupungin ja jokiluonnon väliin 12 metriä korkean teräsbetonimuurin. Kolmannen sukupolven kaupunki on teollisen kaupungin orgaaninen raunio. Symbioosi Taipein kollektiivipuutarho- jen, kaupunkiviljelysten sekä laittomien asuinalueiden ja ympäröivän kaupun- gin välillä ovat Kolmannen sukupolven kaupungin fragmentteja. Nämä alueet ovat kaupungin akupunktiopisteitä, jotka pureutuvat teollisen kuoren läpi kosketuksiin paikallisen tiedon kans- sa. Kolmannen sukupolven kaupun- ki sitoutuu paikalliseen tietoon ja sitä kautta kasvaa kiinni osaksi luontoa. Kaupunkiakupunktio on ekologi- sen kaupunkisuunnittelun teoria, joka yhdistää kaupunkisuunnittelua ja perin- teistä kiinalaista akupunktiolääketieteen teoriaa. Lähtökohtaisesti se havainnoi kaupunkeja monitasoisina elävinä orga- nismeina, joista se pyrkii määrittämään kuntoutusta vaativia alueita. Paikalli- seen traditioon sitoutuvat ja kestävän kehityksen mukaiset projektit toimivat akupunktioneuloina, jotka elvyttävät kokonaisuutta parantamalla sen osia. Raunio on arkkitehtuurin katharsis, jos- sa ihmisen luomasta tulee osa luontoa. Raunio on teollisen kaupungin alitajui- nen haave ja modernin ihmisen trauma. Taipei tarjoaa kehittyneen symbioosi- mallin, jossa mekaaninen kaupunki elää yhteiseloa epävirallisten asuinalueiden, kollektiivipuutarhojen, kaupunkivilje- lysten ja kaupunkinomadien kanssa. Kaavoitus on jätetty puolitiehen ja ih- miset ovat viimeistelleet kaupungin. C-Lab CURE tutkii niitä biourbaaneja prosesseja, jotka kehittävät teollista kaupunkia kohti Kolmannen sukupol- ven kaupunkia.

Paracity on suomalainen keksintouml ja vientituote joka on kehitetty Kiinan Kes-kustaideakatemian pyyn-noumlstauml vaihtoehtoiseksi luontoa kunnioittavaksi kau-punkikehitysmalliksi Paraci-tyn pilottikohteet sijaitsevat Taipein tulvatasankoalueella Pohjois-Fukushiman tsuna-mialueella ja Jakartassa kau-pungin jaumltteitauml kaumlsittelevaumlssauml slummissa Runkomateriaali-na kaumlytettaumlvauml puu on suoma-laisvalmisteinen ristikkaumlinla-minoitu massiivimaumlnty

Paracity is a biourban organ-ism that is growing on the prin-ciples of Open Form individual design-build actions generat-ing spontaneous communica-tive reactions on the surround-ing built human environment and this organic constructivist dialog leading into self-organ-ized community structures development and knowledge building

The growing organism the Paracity is based on a three dimensional wooden prima-ry structure organic grid with spatial modules of 6 x 6 x 6 metres constructed out of CLT cross-laminated timber sticks This simple structure can be modified and grown by the community members working as teams or by an assigned Paracity constructor

The primary structure can grow even on neglected ur-ban areas such as river flood

plains hillsides abandoned industrial areas storm water channels or slums Paracity suites perfectly to flooding and tsunami risk areas and the CLT primary structure has a high standard of earthquake perfor-mance

People will attach their indi-vidual self-made architectural solutions gardens and farms on the primary structure which offers a three dimen-sional building grid for the DIY architecture Primary structure offers the main arteries of wa-ter and human circulation but the finer local knowledge nerv-ous networks are grown by the inhabitants Large parts of the Paracity is occupied by wild and cultivated nature

Paracityrsquos self-sustainable bi-ourban growth is backed up by off-the-grid environmental technology solutions providing methods for water purification

energy production organic waste treatment waste water purification and sludge recy-cling These modular plug-in components can be adjust-ed according to the growth of the Paracity and moreover the whole Paracity is designed not only to treat and circulate its own material streams but to start leaching waste from its host city becoming a pos-itive urban parasite following the similar kind of symbiosis as in-between slums and the surrounding city In a sense Paracity is a high-tech slum which can start tuning the in-dustrial city towards an eco-logically more sustainable di-rection

Paracity is a third generation city an organic machine urban compost which is helping the industrial city to transform into being part of nature

PILOT TAIPEI

The pilot project of the Paracity is growing on an urban farm-ing island of Danshui River Taipei City The island is lo-cated between the Zhongxing and Zhonxiao bridges and is around 1000 meters long and 300 meters wide Paracity Tai-pei is celebrating the original first generation Taipei urban-ism with high level of illegal architecture self-organized communities urban farms community gardens urban nomads and constructive an-archy

Paracity Taipei will be powered mostly by bioenergy that is us-ing the organic waste includ-ing sludge taken from the sur-rounding industrial city and by farming fast growing biomass on the flood banks of the Taipei river system

Environmental technology components are mounted on barges that are plugged into the Paracity maintenance docks Barges can be modified according to the needs of the growing biourbanism

Paracity is based on free flood-ing There are no flood walls The first 6 m level above the ground is not built but the whole city is standing on stilts and thus providing the whole ground floor for community actions nature and space re-quiring recycling yards

Paracity Taipei will construct itself through impacts of a col-lective conscious as a nest of post-industrial insects Parac-ity is estimated to have 15000 ndash 25000 inhabitants

OPEN FORMIn its growth Paracity is follow-ing the organic design meth-odology of Open Form (Os-car Hansen Svein Hatloy) in which community level design is viewed as an open dialog with design actions generating spontaneous design reactions within the surroundings Open Form is close to the original Taiwanese ways of developing the self organized and often ldquoil-legalrdquo communities These mi-crourban settlements are con-taining a high volume of Local Knowledge which we also be-lieve will start composting in Paracity when opening up the community development to the citizens

Centralized architectural con-trol is opened up in order to let nature including human nature to step in The life providing volume of Paracity is 11 exist-ence maximum highest possi-ble life in the given conditions

and more

CLT SKELETONParacity provides the skeleton but citizens bring in the flesh Design should not replace re-ality Flesh is More The skel-eton the primary structure of

Paracity is constructed out of 6 meters long (50x50 cm profile) cross laminated timber CLT sticks which are used to form 6x6x6 m cubes that are piled up to 16 stories high (8 cubes) The CLT primary structure has a fine earthquake performance and it is fire resistant The structural elements sticks with wood joints are prefab-ricated and transported to the Paracity Island on barges The construction work ndash the growing of the Paracity prima-ry organism can be manually done by residents in teams of by professional parasite con-structors The CLT structure is just a landscape on which citizens will attach their own

houses and gardens

ENVIROMENTAL TECHNOLOGYThe biourban growth of the Paracity is supported by high environmental technology which is mounted on barges These modular bio-vessels are attached to the Paracity ser-vice harbour and can be ad-justed according to the needs of the evolving urban organ-ism The post-industrial fleet of bio-vessels can travel along the Taipei river system and is

ready to start the biourban restoration process also from other hot-spots of the river city The environmental technology barges provide solutions for

bull Waste water treatment of Paracity and of the sur-rounding Taipei

bull Water purification The in-frastructural water circula-tion is originated from the polluted Danshui River

bull Sludge treatment for ferti-lizer and bio-energy

bull Closed circuit aquaculture

bull Recycling of construction waste

bull Recycling of organic waste for fertilizer and bio-ener-gy

The barges have no problem with the flooding river

EXISTENCE MAXIMUMParacity is a seed of the Third Generation City the organ-ic ruin of the industrial city (2G) The modular biourban organism is designed to grow following the rule of nature existence maximum The pri-mary structure can be grown by people and after Paracity

has reached the critical mass the life providing system of the CLT structure will start es-calating It will cross the river and start rooting on the flood plains Then it will cross the 12 meters high Taipei flood wall and grow gradually into the city Seeds of the Paracity will start rooting in the urban acu-puncture points of Taipei ille-gal community gardens urban farms abandoned cemeteries and waste-lands From these acupuncture points the Parac-ity will start growing following the covered irrigation systems such as the Liukong Channel and eventually the biourban or-ganism and the static city will find a balance the Third Gen-eration Taipei

PARASITE URBANISMParacity is living off the ma-terial streams from the sur-rounding Taipei Even the pol-luted river is a resource for this biourban intestine Parac-ity is Medieval medicine using leaches to cure the circulation Paracity is letting off the bad blood of Taipei and it uses it a resource In fact it makes money out of the process Of-ficially 37 of the Taipei City

waste water goes untreated to the river Paracity wants it all And it wants all the other ma-terials which the industrial city is regarding as ldquowasterdquo Parac-ity and modern Taipei live in a similar kind of a symbiosis as a slum and the city the urban nomads will clean the static city from its ldquowasterdquo only in Paracity the cleaning and recy-cling process is boosted up by high environmental technolo-gy In a sense the Paracity is a high-tech slum

BIO-ENERGYThe main energy source for the Paracity is bio-energy which is using both treated organic waste and sludge from Parac-ity and surrounding Taipei and especially biomass that is harvested around Paracity and on the flood banks of the Taipei rivers The fertile flood banks flood plains and storm water channels provide ideal cultivation areas for fast grow-ing biomass plantations The vegetation will be harvested by boats and then shipped to Paracity Bio-Energy Facility The growing of the biomass on the river banks will also ben-efit on the natural river resto-ration through root cleansing of sediment pollution and the

biomass will have a positive impact on the Taipei micro cli-mate and urban ecology

MediatorAfter rooting on the riverside and gaining a critical mass the Paracity will climb over the 12 meters high reinforced con-crete flood wall which is sepa-rating modern Taipei from the rivers and nature The flood wall will remain in the guts of the Paracity but the new struc-ture enables Taipei citizens to fluently reach the river Parac-ity will reunite the river reality and the urban fiction Parac-ity is a mediator between the modern city and nature

BIOCLIMATIC ARCHITECTUREParacity has a lot of holes gaps and nature in-between houses The system is ventilat-ing itself like a large scale bee-hive of post-industrial insects The different temperatures of the roofs gardens water bod-ies and shaded platforms will generate small winds between them and the hot roofs will start sucking in breeze from the cooler river Also the indi-vidual houses should follow the traditional principles of bi-

oclimatic architecture and not rely on mechanical air-condi-tioning

FREE FLOODINGParacity is based on free flood-ing The whole city is standing on stilts allowing the river to pulsate freely with the frequent typhoons and storm waters The environmental technology of the Paracity is mounted on barges which have no problem with the flooding either Actu-ally the Paracity is an organic architectural flood itself ready to cross the flood wall of Taipei and spread into the mechani-cal city

BIOURBAN RESTORATIONParacity is a positive organic tumour in the mechanical tis-sue of Taipei While it is leach-ing and processing the indus-trial and organic waste of the city it is gaining momentum in its growth and becomes more and more important to the static industrial urbanism Paracity is an alternative real-ity within the industrial devel-opment and will start treating the city the same ways as the urban acupuncture points of illegal community gardens and

urban farms of Taipei do today Paracity has the ability to be-come a network of biourban acupuncture tuning the whole industrial city towards the or-ganic ruining the industrialism on its way to become part of nature the Third Generation City

ORGANIC LAYERSThe biourbanism of the Parac-ity is as much landscape as it is architecture The totalitari-an landscape-architecture of Paracity includes organic lay-ers for natural water purifica-tion and treatment community gardening farming and bio-mass production as an energy source Infrastructure and ir-rigation water originates from the polluted Danshui river and will be both chemically and bi-ologically purified before being used in the farms gardens and houses of the community The chemically purified water gets pumped to the roof parks on the top level of the Paracity from where the gravity will cir-culate the water into the three dimensional irrigation sys-tems

ADAPTABILITYThe pilot-project of the Paraci-ty is designed in Taipei but the solution is developed to work in different locations around the world Paracity offers an alter-native for the Chinese strategic urban planning to start ecolog-ically harmonizing the grow-ing river cities of China And Paracity can be used as urban acupuncture for the emerging cities of China and elsewhere Paracity can grow along the Oshiwara chain of slums in Mumbai providing better liv-ing conditions cleaning up the Oshiwara River and more effectively treating the urban waste that is flooding in from the surrounding city Paracity can parachute into Nairobi and start growing from the fertile top-soil of the slums Paracity should grow into the favelas of Brazil and start celebrating the local knowledge of these organic communities Paracity is organic adaptable and wel-comes local knowledge The city is built by hands of a high diversity of different people

LOCAL KNOWLEDGEParacity is inspired by the Lo-cal Knowledge of Taipei the original Taiwanese urban ele-

ments that include a high level of self-made ldquoillegalrdquo archi-tecture self-organized com-munities extensive networks of self-organized community gardens and urban farms fluid nomadic ways of using the city communicative collective sub-conscious in community and urban scale feeling of domi-nating the no-manrsquos land by human nature and other forms of constructive anarchy The Paracity basically only pro-vides the primary structure the three dimensional landscape for the Local Knowledge to be attached and grow The prima-ry structure and the environ-mental technology solutions will remain pretty much the same no matter in which cul-ture the Paracity starts to grow but the real human layer of DIY architecture and gardens will follow the Local Knowledge of the respective culture and site Paracity is always site-specific and it is always local

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ture the Peoplersquos Architecture or Weak Architecture The theory of urban acupuncture suggests that scores of small-scale less costly and localized projects is what cit-ies need in order to recover and re-new themselves

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

Paracity on modulaariseen massiivipuurunkoon perus-tuva kaupunkirakennejaumlrjes-telmauml johon kaupunkilaiset itse rakentavat omat kotinsa yhteisoumlnsauml ja viljelyksensauml Orgaaninen Paracity kasvaa itsenaumlisesti olevien kaupun-kien jaumlttoumlmaille kuten tulva-tasangoille tai slummehin It-senaumlisen kasvun mahdollistaa modulaarinen ympaumlristoumltek-nologia joka tuottaa syntyville yhdyskunnille niiden tarvitse-mat sisaumlelimet Paracity vas-taanottaa kaumlsittelee ja muun-taa resursseiksi ympaumlroumlivaumln kaupungin tuottaman jaumltteen toimien positiivisena akupunk-tioneulana saastuttavalle kau-pungille

Paracity on suomalainen keksintouml ja vientituote joka on kehitetty Kiinan Kes-kustaideakatemian pyyn-noumlstauml vaihtoehtoiseksi luontoa kunnioittavaksi kau-punkikehitysmalliksi Paraci-tyn pilottikohteet sijaitsevat Taipein tulvatasankoalueella Pohjois-Fukushiman tsuna-mialueella ja Jakartassa kau-pungin jaumltteitauml kaumlsittelevaumlssauml slummissa Runkomateriaali-na kaumlytettaumlvauml puu on suoma-laisvalmisteinen ristikkaumlinla-minoitu massiivimaumlnty

Paracity is a biourban organ-ism that is growing on the prin-ciples of Open Form individual design-build actions generat-ing spontaneous communica-tive reactions on the surround-ing built human environment and this organic constructivist dialog leading into self-organ-ized community structures development and knowledge building

The growing organism the Paracity is based on a three dimensional wooden prima-ry structure organic grid with spatial modules of 6 x 6 x 6 metres constructed out of CLT cross-laminated timber sticks This simple structure can be modified and grown by the community members working as teams or by an assigned Paracity constructor

The primary structure can grow even on neglected ur-ban areas such as river flood

plains hillsides abandoned industrial areas storm water channels or slums Paracity suites perfectly to flooding and tsunami risk areas and the CLT primary structure has a high standard of earthquake perfor-mance

People will attach their indi-vidual self-made architectural solutions gardens and farms on the primary structure which offers a three dimen-sional building grid for the DIY architecture Primary structure offers the main arteries of wa-ter and human circulation but the finer local knowledge nerv-ous networks are grown by the inhabitants Large parts of the Paracity is occupied by wild and cultivated nature

Paracityrsquos self-sustainable bi-ourban growth is backed up by off-the-grid environmental technology solutions providing methods for water purification

energy production organic waste treatment waste water purification and sludge recy-cling These modular plug-in components can be adjust-ed according to the growth of the Paracity and moreover the whole Paracity is designed not only to treat and circulate its own material streams but to start leaching waste from its host city becoming a pos-itive urban parasite following the similar kind of symbiosis as in-between slums and the surrounding city In a sense Paracity is a high-tech slum which can start tuning the in-dustrial city towards an eco-logically more sustainable di-rection

Paracity is a third generation city an organic machine urban compost which is helping the industrial city to transform into being part of nature

PILOT TAIPEI

The pilot project of the Paracity is growing on an urban farm-ing island of Danshui River Taipei City The island is lo-cated between the Zhongxing and Zhonxiao bridges and is around 1000 meters long and 300 meters wide Paracity Tai-pei is celebrating the original first generation Taipei urban-ism with high level of illegal architecture self-organized communities urban farms community gardens urban nomads and constructive an-archy

Paracity Taipei will be powered mostly by bioenergy that is us-ing the organic waste includ-ing sludge taken from the sur-rounding industrial city and by farming fast growing biomass on the flood banks of the Taipei river system

Environmental technology components are mounted on barges that are plugged into the Paracity maintenance docks Barges can be modified according to the needs of the growing biourbanism

Paracity is based on free flood-ing There are no flood walls The first 6 m level above the ground is not built but the whole city is standing on stilts and thus providing the whole ground floor for community actions nature and space re-quiring recycling yards

Paracity Taipei will construct itself through impacts of a col-lective conscious as a nest of post-industrial insects Parac-ity is estimated to have 15000 ndash 25000 inhabitants

OPEN FORMIn its growth Paracity is follow-ing the organic design meth-odology of Open Form (Os-car Hansen Svein Hatloy) in which community level design is viewed as an open dialog with design actions generating spontaneous design reactions within the surroundings Open Form is close to the original Taiwanese ways of developing the self organized and often ldquoil-legalrdquo communities These mi-crourban settlements are con-taining a high volume of Local Knowledge which we also be-lieve will start composting in Paracity when opening up the community development to the citizens

Centralized architectural con-trol is opened up in order to let nature including human nature to step in The life providing volume of Paracity is 11 exist-ence maximum highest possi-ble life in the given conditions

and more

CLT SKELETONParacity provides the skeleton but citizens bring in the flesh Design should not replace re-ality Flesh is More The skel-eton the primary structure of

Paracity is constructed out of 6 meters long (50x50 cm profile) cross laminated timber CLT sticks which are used to form 6x6x6 m cubes that are piled up to 16 stories high (8 cubes) The CLT primary structure has a fine earthquake performance and it is fire resistant The structural elements sticks with wood joints are prefab-ricated and transported to the Paracity Island on barges The construction work ndash the growing of the Paracity prima-ry organism can be manually done by residents in teams of by professional parasite con-structors The CLT structure is just a landscape on which citizens will attach their own

houses and gardens

ENVIROMENTAL TECHNOLOGYThe biourban growth of the Paracity is supported by high environmental technology which is mounted on barges These modular bio-vessels are attached to the Paracity ser-vice harbour and can be ad-justed according to the needs of the evolving urban organ-ism The post-industrial fleet of bio-vessels can travel along the Taipei river system and is

ready to start the biourban restoration process also from other hot-spots of the river city The environmental technology barges provide solutions for

bull Waste water treatment of Paracity and of the sur-rounding Taipei

bull Water purification The in-frastructural water circula-tion is originated from the polluted Danshui River

bull Sludge treatment for ferti-lizer and bio-energy

bull Closed circuit aquaculture

bull Recycling of construction waste

bull Recycling of organic waste for fertilizer and bio-ener-gy

The barges have no problem with the flooding river

EXISTENCE MAXIMUMParacity is a seed of the Third Generation City the organ-ic ruin of the industrial city (2G) The modular biourban organism is designed to grow following the rule of nature existence maximum The pri-mary structure can be grown by people and after Paracity

has reached the critical mass the life providing system of the CLT structure will start es-calating It will cross the river and start rooting on the flood plains Then it will cross the 12 meters high Taipei flood wall and grow gradually into the city Seeds of the Paracity will start rooting in the urban acu-puncture points of Taipei ille-gal community gardens urban farms abandoned cemeteries and waste-lands From these acupuncture points the Parac-ity will start growing following the covered irrigation systems such as the Liukong Channel and eventually the biourban or-ganism and the static city will find a balance the Third Gen-eration Taipei

PARASITE URBANISMParacity is living off the ma-terial streams from the sur-rounding Taipei Even the pol-luted river is a resource for this biourban intestine Parac-ity is Medieval medicine using leaches to cure the circulation Paracity is letting off the bad blood of Taipei and it uses it a resource In fact it makes money out of the process Of-ficially 37 of the Taipei City

waste water goes untreated to the river Paracity wants it all And it wants all the other ma-terials which the industrial city is regarding as ldquowasterdquo Parac-ity and modern Taipei live in a similar kind of a symbiosis as a slum and the city the urban nomads will clean the static city from its ldquowasterdquo only in Paracity the cleaning and recy-cling process is boosted up by high environmental technolo-gy In a sense the Paracity is a high-tech slum

BIO-ENERGYThe main energy source for the Paracity is bio-energy which is using both treated organic waste and sludge from Parac-ity and surrounding Taipei and especially biomass that is harvested around Paracity and on the flood banks of the Taipei rivers The fertile flood banks flood plains and storm water channels provide ideal cultivation areas for fast grow-ing biomass plantations The vegetation will be harvested by boats and then shipped to Paracity Bio-Energy Facility The growing of the biomass on the river banks will also ben-efit on the natural river resto-ration through root cleansing of sediment pollution and the

ELEMENTSPicture Niilo Tenkanen

9Habitare amp FinnBuild 2014

biomass will have a positive impact on the Taipei micro cli-mate and urban ecology

MediatorAfter rooting on the riverside and gaining a critical mass the Paracity will climb over the 12 meters high reinforced con-crete flood wall which is sepa-rating modern Taipei from the rivers and nature The flood wall will remain in the guts of the Paracity but the new struc-ture enables Taipei citizens to fluently reach the river Parac-ity will reunite the river reality and the urban fiction Parac-ity is a mediator between the modern city and nature

BIOCLIMATIC ARCHITECTUREParacity has a lot of holes gaps and nature in-between houses The system is ventilat-ing itself like a large scale bee-hive of post-industrial insects The different temperatures of the roofs gardens water bod-ies and shaded platforms will generate small winds between them and the hot roofs will start sucking in breeze from the cooler river Also the indi-vidual houses should follow the traditional principles of bi-

oclimatic architecture and not rely on mechanical air-condi-tioning

FREE FLOODINGParacity is based on free flood-ing The whole city is standing on stilts allowing the river to pulsate freely with the frequent typhoons and storm waters The environmental technology of the Paracity is mounted on barges which have no problem with the flooding either Actu-ally the Paracity is an organic architectural flood itself ready to cross the flood wall of Taipei and spread into the mechani-cal city

BIOURBAN RESTORATIONParacity is a positive organic tumour in the mechanical tis-sue of Taipei While it is leach-ing and processing the indus-trial and organic waste of the city it is gaining momentum in its growth and becomes more and more important to the static industrial urbanism Paracity is an alternative real-ity within the industrial devel-opment and will start treating the city the same ways as the urban acupuncture points of illegal community gardens and

urban farms of Taipei do today Paracity has the ability to be-come a network of biourban acupuncture tuning the whole industrial city towards the or-ganic ruining the industrialism on its way to become part of nature the Third Generation City

ORGANIC LAYERSThe biourbanism of the Parac-ity is as much landscape as it is architecture The totalitari-an landscape-architecture of Paracity includes organic lay-ers for natural water purifica-tion and treatment community gardening farming and bio-mass production as an energy source Infrastructure and ir-rigation water originates from the polluted Danshui river and will be both chemically and bi-ologically purified before being used in the farms gardens and houses of the community The chemically purified water gets pumped to the roof parks on the top level of the Paracity from where the gravity will cir-culate the water into the three dimensional irrigation sys-tems

ADAPTABILITYThe pilot-project of the Paraci-ty is designed in Taipei but the solution is developed to work in different locations around the world Paracity offers an alter-native for the Chinese strategic urban planning to start ecolog-ically harmonizing the grow-ing river cities of China And Paracity can be used as urban acupuncture for the emerging cities of China and elsewhere Paracity can grow along the Oshiwara chain of slums in Mumbai providing better liv-ing conditions cleaning up the Oshiwara River and more effectively treating the urban waste that is flooding in from the surrounding city Paracity can parachute into Nairobi and start growing from the fertile top-soil of the slums Paracity should grow into the favelas of Brazil and start celebrating the local knowledge of these organic communities Paracity is organic adaptable and wel-comes local knowledge The city is built by hands of a high diversity of different people

LOCAL KNOWLEDGEParacity is inspired by the Lo-cal Knowledge of Taipei the original Taiwanese urban ele-

ments that include a high level of self-made ldquoillegalrdquo archi-tecture self-organized com-munities extensive networks of self-organized community gardens and urban farms fluid nomadic ways of using the city communicative collective sub-conscious in community and urban scale feeling of domi-nating the no-manrsquos land by human nature and other forms of constructive anarchy The Paracity basically only pro-vides the primary structure the three dimensional landscape for the Local Knowledge to be attached and grow The prima-ry structure and the environ-mental technology solutions will remain pretty much the same no matter in which cul-ture the Paracity starts to grow but the real human layer of DIY architecture and gardens will follow the Local Knowledge of the respective culture and site Paracity is always site-specific and it is always local

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ture the Peoplersquos Architecture or Weak Architecture The theory of urban acupuncture suggests that scores of small-scale less costly and localized projects is what cit-ies need in order to recover and re-new themselves

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Modernismi naumlkee kaupun-gin koneena ndash biourbanis-mille kaupunki on organismi Modernistisessa kaupunki-suunnittelussa joka on ollut vallitseva suunnittelupara-digma viimeiset 70-80 vuotta on vakavia puutteita joihin biourbaani kaupunkisuunnit-telu vastaa Paracity tarjoaa biourbaaneja suunnittelurat-kaisuja kaumlytaumlnnoumlssauml

Biourbanismille ihminen ei ole kone Ihminen on organismi kaupunki on organismi kau-punkien verkosto on orga-nismi Kaupunki muodostuu useista toisiinsa dynaamisesti linkittyneistauml kerroksista mut-ta linkit eivaumlt ole suoraviivaisia Kaupungin orgaaninen raken-ne aiheuttaa sen ettauml kaupun-gin kehittyminen ja ihmisten toiminta kaupungissa ei ole ennustettavissa Kaupunki ja sen ihmiset ovat rationaalisia vain osittain sattuma on kont-rollia arvokkaampaa Tarpeet ja halut vaihtelevat niin per-soonien vaumllillauml kuin ajallisesti Emme tiedauml miltauml maailma naumlyttaumlauml 2020-luvulla Kuinka voisimme tietaumlauml millaisessa kaupungissa ihmiset haluavat silloin elaumlauml Kaupungin taumlytyy pystyauml korjaamaan itsensauml biologisen organismin tavoin

Biourbaani kaupunki (kuten Paracity) tarjoaa rungon johon kaupunki voi kasvaa Paracity on kaupungin luuranko joka antaa tuen elaumlmaumllle Se ei nojaa arkkitehtien ja kaupunkisuun-nittelijoiden taitoon ennakoida tulevaa Sen sijaan Paracityn pohjana on paikallinen traditio Taipeissa elaumlauml edelleen vah-va perinne rakentaa ja viljellauml urbaanin kaupungin jakojaumlaumln-noumlsalueita Taipeissa kaikkiin

COMMEDIA

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

from Andrei Tarkowskirsquos Stalker (1979 Mosfilm)

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

Paracity is a biourban organ-ism that is growing on the prin-ciples of Open Form individual design-build actions generat-ing spontaneous communica-tive reactions on the surround-ing built human environment and this organic constructivist dialog leading into self-organ-ized community structures development and knowledge building

The growing organism the Paracity is based on a three dimensional wooden prima-ry structure organic grid with spatial modules of 6 x 6 x 6 metres constructed out of CLT cross-laminated timber sticks This simple structure can be modified and grown by the community members working as teams or by an assigned Paracity constructor

The primary structure can grow even on neglected ur-ban areas such as river flood

plains hillsides abandoned industrial areas storm water channels or slums Paracity suites perfectly to flooding and tsunami risk areas and the CLT primary structure has a high standard of earthquake perfor-mance

People will attach their indi-vidual self-made architectural solutions gardens and farms on the primary structure which offers a three dimen-sional building grid for the DIY architecture Primary structure offers the main arteries of wa-ter and human circulation but the finer local knowledge nerv-ous networks are grown by the inhabitants Large parts of the Paracity is occupied by wild and cultivated nature

Paracityrsquos self-sustainable bi-ourban growth is backed up by off-the-grid environmental technology solutions providing methods for water purification

energy production organic waste treatment waste water purification and sludge recy-cling These modular plug-in components can be adjust-ed according to the growth of the Paracity and moreover the whole Paracity is designed not only to treat and circulate its own material streams but to start leaching waste from its host city becoming a pos-itive urban parasite following the similar kind of symbiosis as in-between slums and the surrounding city In a sense Paracity is a high-tech slum which can start tuning the in-dustrial city towards an eco-logically more sustainable di-rection

Paracity is a third generation city an organic machine urban compost which is helping the industrial city to transform into being part of nature

The pilot project of the Paracity is growing on an urban farm-ing island of Danshui River Taipei City The island is lo-cated between the Zhongxing and Zhonxiao bridges and is around 1000 meters long and 300 meters wide Paracity Tai-pei is celebrating the original first generation Taipei urban-ism with high level of illegal architecture self-organized communities urban farms community gardens urban nomads and constructive an-archy

Paracity Taipei will be powered mostly by bioenergy that is us-ing the organic waste includ-ing sludge taken from the sur-rounding industrial city and by farming fast growing biomass on the flood banks of the Taipei river system

Environmental technology components are mounted on barges that are plugged into the Paracity maintenance docks Barges can be modified according to the needs of the growing biourbanism

Paracity is based on free flood-ing There are no flood walls The first 6 m level above the ground is not built but the whole city is standing on stilts and thus providing the whole ground floor for community actions nature and space re-quiring recycling yards

OPEN FORMIn its growth Paracity is follow-ing the organic design meth-odology of Open Form (Os-car Hansen Svein Hatloy) in which community level design is viewed as an open dialog with design actions generating spontaneous design reactions within the surroundings Open Form is close to the original Taiwanese ways of developing the self organized and often ldquoil-legalrdquo communities These mi-crourban settlements are con-taining a high volume of Local Knowledge which we also be-lieve will start composting in Paracity when opening up the community development to the citizens

Centralized architectural con-trol is opened up in order to let nature including human nature to step in The life providing volume of Paracity is 11 exist-ence maximum highest possi-ble life in the given conditions

and more

CLT SKELETONParacity provides the skeleton but citizens bring in the flesh Design should not replace re-ality Flesh is More The skel-eton the primary structure of

Paracity is constructed out of 6 meters long (50x50 cm profile) cross laminated timber CLT sticks which are used to form 6x6x6 m cubes that are piled up to 16 stories high (8 cubes) The CLT primary structure has a fine earthquake performance and it is fire resistant The structural elements sticks with wood joints are prefab-ricated and transported to the Paracity Island on barges The construction work ndash the growing of the Paracity prima-ry organism can be manually done by residents in teams of by professional parasite con-structors The CLT structure is just a landscape on which citizens will attach their own

houses and gardens

ENVIROMENTAL TECHNOLOGYThe biourban growth of the Paracity is supported by high environmental technology which is mounted on barges These modular bio-vessels are attached to the Paracity ser-vice harbour and can be ad-justed according to the needs of the evolving urban organ-ism The post-industrial fleet of bio-vessels can travel along the Taipei river system and is

ready to start the biourban restoration process also from other hot-spots of the river city The environmental technology barges provide solutions for

bull Waste water treatment of Paracity and of the sur-rounding Taipei

bull Water purification The in-frastructural water circula-tion is originated from the polluted Danshui River

bull Sludge treatment for ferti-lizer and bio-energy

bull Closed circuit aquaculture

bull Recycling of construction waste

bull Recycling of organic waste for fertilizer and bio-ener-gy

The barges have no problem with the flooding river

EXISTENCE MAXIMUMParacity is a seed of the Third Generation City the organ-ic ruin of the industrial city (2G) The modular biourban organism is designed to grow following the rule of nature existence maximum The pri-mary structure can be grown by people and after Paracity

has reached the critical mass the life providing system of the CLT structure will start es-calating It will cross the river and start rooting on the flood plains Then it will cross the 12 meters high Taipei flood wall and grow gradually into the city Seeds of the Paracity will start rooting in the urban acu-puncture points of Taipei ille-gal community gardens urban farms abandoned cemeteries and waste-lands From these acupuncture points the Parac-ity will start growing following the covered irrigation systems such as the Liukong Channel and eventually the biourban or-ganism and the static city will find a balance the Third Gen-eration Taipei

PARASITE URBANISMParacity is living off the ma-terial streams from the sur-rounding Taipei Even the pol-luted river is a resource for this biourban intestine Parac-ity is Medieval medicine using leaches to cure the circulation Paracity is letting off the bad blood of Taipei and it uses it a resource In fact it makes money out of the process Of-ficially 37 of the Taipei City

waste water goes untreated to the river Paracity wants it all And it wants all the other ma-terials which the industrial city is regarding as ldquowasterdquo Parac-ity and modern Taipei live in a similar kind of a symbiosis as a slum and the city the urban nomads will clean the static city from its ldquowasterdquo only in Paracity the cleaning and recy-cling process is boosted up by high environmental technolo-gy In a sense the Paracity is a high-tech slum

BIO-ENERGYThe main energy source for the Paracity is bio-energy which is using both treated organic waste and sludge from Parac-ity and surrounding Taipei and especially biomass that is harvested around Paracity and on the flood banks of the Taipei rivers The fertile flood banks flood plains and storm water channels provide ideal cultivation areas for fast grow-ing biomass plantations The vegetation will be harvested by boats and then shipped to Paracity Bio-Energy Facility The growing of the biomass on the river banks will also ben-efit on the natural river resto-ration through root cleansing of sediment pollution and the

biomass will have a positive impact on the Taipei micro cli-mate and urban ecology

MediatorAfter rooting on the riverside and gaining a critical mass the Paracity will climb over the 12 meters high reinforced con-crete flood wall which is sepa-rating modern Taipei from the rivers and nature The flood wall will remain in the guts of the Paracity but the new struc-ture enables Taipei citizens to fluently reach the river Parac-ity will reunite the river reality and the urban fiction Parac-ity is a mediator between the modern city and nature

BIOCLIMATIC ARCHITECTUREParacity has a lot of holes gaps and nature in-between houses The system is ventilat-ing itself like a large scale bee-hive of post-industrial insects The different temperatures of the roofs gardens water bod-ies and shaded platforms will generate small winds between them and the hot roofs will start sucking in breeze from the cooler river Also the indi-vidual houses should follow the traditional principles of bi-

oclimatic architecture and not rely on mechanical air-condi-tioning

FREE FLOODINGParacity is based on free flood-ing The whole city is standing on stilts allowing the river to pulsate freely with the frequent typhoons and storm waters The environmental technology of the Paracity is mounted on barges which have no problem with the flooding either Actu-ally the Paracity is an organic architectural flood itself ready to cross the flood wall of Taipei and spread into the mechani-cal city

BIOURBAN RESTORATIONParacity is a positive organic tumour in the mechanical tis-sue of Taipei While it is leach-ing and processing the indus-trial and organic waste of the city it is gaining momentum in its growth and becomes more and more important to the static industrial urbanism Paracity is an alternative real-ity within the industrial devel-opment and will start treating the city the same ways as the urban acupuncture points of illegal community gardens and

urban farms of Taipei do today Paracity has the ability to be-come a network of biourban acupuncture tuning the whole industrial city towards the or-ganic ruining the industrialism on its way to become part of nature the Third Generation City

ORGANIC LAYERSThe biourbanism of the Parac-ity is as much landscape as it is architecture The totalitari-an landscape-architecture of Paracity includes organic lay-ers for natural water purifica-tion and treatment community gardening farming and bio-mass production as an energy source Infrastructure and ir-rigation water originates from the polluted Danshui river and will be both chemically and bi-ologically purified before being used in the farms gardens and houses of the community The chemically purified water gets pumped to the roof parks on the top level of the Paracity from where the gravity will cir-culate the water into the three dimensional irrigation sys-tems

ADAPTABILITYThe pilot-project of the Paraci-ty is designed in Taipei but the solution is developed to work in different locations around the world Paracity offers an alter-native for the Chinese strategic urban planning to start ecolog-ically harmonizing the grow-ing river cities of China And Paracity can be used as urban acupuncture for the emerging cities of China and elsewhere Paracity can grow along the Oshiwara chain of slums in Mumbai providing better liv-ing conditions cleaning up the Oshiwara River and more effectively treating the urban waste that is flooding in from the surrounding city Paracity can parachute into Nairobi and start growing from the fertile top-soil of the slums Paracity should grow into the favelas of Brazil and start celebrating the local knowledge of these organic communities Paracity is organic adaptable and wel-comes local knowledge The city is built by hands of a high diversity of different people

LOCAL KNOWLEDGEParacity is inspired by the Lo-cal Knowledge of Taipei the original Taiwanese urban ele-

ments that include a high level of self-made ldquoillegalrdquo archi-tecture self-organized com-munities extensive networks of self-organized community gardens and urban farms fluid nomadic ways of using the city communicative collective sub-conscious in community and urban scale feeling of domi-nating the no-manrsquos land by human nature and other forms of constructive anarchy The Paracity basically only pro-vides the primary structure the three dimensional landscape for the Local Knowledge to be attached and grow The prima-ry structure and the environ-mental technology solutions will remain pretty much the same no matter in which cul-ture the Paracity starts to grow but the real human layer of DIY architecture and gardens will follow the Local Knowledge of the respective culture and site Paracity is always site-specific and it is always local

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

ldquoWe need a recognized certification system that in-corporates our specificities and realities promotes the value of our forest products and ensures an equal share of benefits along the value chain Our stakehold-ers are motivated by the bottom-up approach keen to participate in the creation of their own certification system and wanting to ensure they understand their system once it is readyrdquo

Christine Nkene PAFC Cameroon

ldquoPrivate forest owners in Hungary view PEFC certifi-cation as their only affordable option and everyone including those already involved with other systems value PEFC for respecting our natural economic and social environment Legislative developments like the European Union Timber Regulation have also drawn the stakeholdersrsquo attention towards certificationrdquo

ldquoCommunity forestry is successful here with over 18000 community forestry user groups managing about 17 million ha of forest We have proven our-selves in forest protection

but there is a need to enhance our rural livelihood op-portunities through sustainable forest management Developing a PEFC-endorsed national forest certifica-tion scheme will help us to build recognition through-out the country on the potential for managing forests sustainablyrdquo

Ghan Shyam Pandey Green Foundation Nepal

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

OPEN FORMIn its growth Paracity is follow-ing the organic design meth-odology of Open Form (Os-car Hansen Svein Hatloy) in which community level design is viewed as an open dialog with design actions generating spontaneous design reactions within the surroundings Open Form is close to the original Taiwanese ways of developing the self organized and often ldquoil-legalrdquo communities These mi-crourban settlements are con-taining a high volume of Local Knowledge which we also be-lieve will start composting in Paracity when opening up the community development to the citizens

Centralized architectural con-trol is opened up in order to let nature including human nature to step in The life providing volume of Paracity is 11 exist-ence maximum highest possi-ble life in the given conditions

and more

CLT SKELETONParacity provides the skeleton but citizens bring in the flesh Design should not replace re-ality Flesh is More The skel-eton the primary structure of

Paracity is constructed out of 6 meters long (50x50 cm profile) cross laminated timber CLT sticks which are used to form 6x6x6 m cubes that are piled up to 16 stories high (8 cubes) The CLT primary structure has a fine earthquake performance and it is fire resistant The structural elements sticks with wood joints are prefab-ricated and transported to the Paracity Island on barges The construction work ndash the growing of the Paracity prima-ry organism can be manually done by residents in teams of by professional parasite con-structors The CLT structure is just a landscape on which citizens will attach their own

houses and gardens

ENVIROMENTAL TECHNOLOGYThe biourban growth of the Paracity is supported by high environmental technology which is mounted on barges These modular bio-vessels are attached to the Paracity ser-vice harbour and can be ad-justed according to the needs of the evolving urban organ-ism The post-industrial fleet of bio-vessels can travel along the Taipei river system and is

ready to start the biourban restoration process also from other hot-spots of the river city The environmental technology barges provide solutions for

bull Water purification The in-frastructural water circula-tion is originated from the polluted Danshui River

bull Sludge treatment for ferti-lizer and bio-energy

bull Closed circuit aquaculture

bull Recycling of construction waste

bull Recycling of organic waste for fertilizer and bio-ener-gy

The barges have no problem with the flooding river

EXISTENCE MAXIMUMParacity is a seed of the Third Generation City the organ-ic ruin of the industrial city (2G) The modular biourban organism is designed to grow following the rule of nature existence maximum The pri-mary structure can be grown by people and after Paracity

has reached the critical mass the life providing system of the CLT structure will start es-calating It will cross the river and start rooting on the flood plains Then it will cross the 12 meters high Taipei flood wall and grow gradually into the city Seeds of the Paracity will start rooting in the urban acu-puncture points of Taipei ille-gal community gardens urban farms abandoned cemeteries and waste-lands From these acupuncture points the Parac-ity will start growing following the covered irrigation systems such as the Liukong Channel and eventually the biourban or-ganism and the static city will find a balance the Third Gen-eration Taipei

PARASITE URBANISMParacity is living off the ma-terial streams from the sur-rounding Taipei Even the pol-luted river is a resource for this biourban intestine Parac-ity is Medieval medicine using leaches to cure the circulation Paracity is letting off the bad blood of Taipei and it uses it a resource In fact it makes money out of the process Of-ficially 37 of the Taipei City

waste water goes untreated to the river Paracity wants it all And it wants all the other ma-terials which the industrial city is regarding as ldquowasterdquo Parac-ity and modern Taipei live in a similar kind of a symbiosis as a slum and the city the urban nomads will clean the static city from its ldquowasterdquo only in Paracity the cleaning and recy-cling process is boosted up by high environmental technolo-gy In a sense the Paracity is a high-tech slum

BIO-ENERGYThe main energy source for the Paracity is bio-energy which is using both treated organic waste and sludge from Parac-ity and surrounding Taipei and especially biomass that is harvested around Paracity and on the flood banks of the Taipei rivers The fertile flood banks flood plains and storm water channels provide ideal cultivation areas for fast grow-ing biomass plantations The vegetation will be harvested by boats and then shipped to Paracity Bio-Energy Facility The growing of the biomass on the river banks will also ben-efit on the natural river resto-ration through root cleansing of sediment pollution and the

biomass will have a positive impact on the Taipei micro cli-mate and urban ecology

MediatorAfter rooting on the riverside and gaining a critical mass the Paracity will climb over the 12 meters high reinforced con-crete flood wall which is sepa-rating modern Taipei from the rivers and nature The flood wall will remain in the guts of the Paracity but the new struc-ture enables Taipei citizens to fluently reach the river Parac-ity will reunite the river reality and the urban fiction Parac-ity is a mediator between the modern city and nature

BIOCLIMATIC ARCHITECTUREParacity has a lot of holes gaps and nature in-between houses The system is ventilat-ing itself like a large scale bee-hive of post-industrial insects The different temperatures of the roofs gardens water bod-ies and shaded platforms will generate small winds between them and the hot roofs will start sucking in breeze from the cooler river Also the indi-vidual houses should follow the traditional principles of bi-

oclimatic architecture and not rely on mechanical air-condi-tioning

FREE FLOODINGParacity is based on free flood-ing The whole city is standing on stilts allowing the river to pulsate freely with the frequent typhoons and storm waters The environmental technology of the Paracity is mounted on barges which have no problem with the flooding either Actu-ally the Paracity is an organic architectural flood itself ready to cross the flood wall of Taipei and spread into the mechani-cal city

BIOURBAN RESTORATIONParacity is a positive organic tumour in the mechanical tis-sue of Taipei While it is leach-ing and processing the indus-trial and organic waste of the city it is gaining momentum in its growth and becomes more and more important to the static industrial urbanism Paracity is an alternative real-ity within the industrial devel-opment and will start treating the city the same ways as the urban acupuncture points of illegal community gardens and

urban farms of Taipei do today Paracity has the ability to be-come a network of biourban acupuncture tuning the whole industrial city towards the or-ganic ruining the industrialism on its way to become part of nature the Third Generation City

ORGANIC LAYERSThe biourbanism of the Parac-ity is as much landscape as it is architecture The totalitari-an landscape-architecture of Paracity includes organic lay-ers for natural water purifica-tion and treatment community gardening farming and bio-mass production as an energy source Infrastructure and ir-rigation water originates from the polluted Danshui river and will be both chemically and bi-ologically purified before being used in the farms gardens and houses of the community The chemically purified water gets pumped to the roof parks on the top level of the Paracity from where the gravity will cir-culate the water into the three dimensional irrigation sys-tems

ADAPTABILITYThe pilot-project of the Paraci-ty is designed in Taipei but the solution is developed to work in different locations around the world Paracity offers an alter-native for the Chinese strategic urban planning to start ecolog-ically harmonizing the grow-ing river cities of China And Paracity can be used as urban acupuncture for the emerging cities of China and elsewhere Paracity can grow along the Oshiwara chain of slums in Mumbai providing better liv-ing conditions cleaning up the Oshiwara River and more effectively treating the urban waste that is flooding in from the surrounding city Paracity can parachute into Nairobi and start growing from the fertile top-soil of the slums Paracity should grow into the favelas of Brazil and start celebrating the local knowledge of these organic communities Paracity is organic adaptable and wel-comes local knowledge The city is built by hands of a high diversity of different people

LOCAL KNOWLEDGEParacity is inspired by the Lo-cal Knowledge of Taipei the original Taiwanese urban ele-

ments that include a high level of self-made ldquoillegalrdquo archi-tecture self-organized com-munities extensive networks of self-organized community gardens and urban farms fluid nomadic ways of using the city communicative collective sub-conscious in community and urban scale feeling of domi-nating the no-manrsquos land by human nature and other forms of constructive anarchy The Paracity basically only pro-vides the primary structure the three dimensional landscape for the Local Knowledge to be attached and grow The prima-ry structure and the environ-mental technology solutions will remain pretty much the same no matter in which cul-ture the Paracity starts to grow but the real human layer of DIY architecture and gardens will follow the Local Knowledge of the respective culture and site Paracity is always site-specific and it is always local

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ture the Peoplersquos Architecture or Weak Architecture The theory of urban acupuncture suggests that scores of small-scale less costly and localized projects is what cit-ies need in order to recover and re-new themselves

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Modernismi naumlkee kaupun-gin koneena ndash biourbanis-mille kaupunki on organismi Modernistisessa kaupunki-suunnittelussa joka on ollut vallitseva suunnittelupara-digma viimeiset 70-80 vuotta on vakavia puutteita joihin biourbaani kaupunkisuunnit-telu vastaa Paracity tarjoaa biourbaaneja suunnittelurat-kaisuja kaumlytaumlnnoumlssauml

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

OPEN FORMIn its growth Paracity is follow-ing the organic design meth-odology of Open Form (Os-car Hansen Svein Hatloy) in which community level design is viewed as an open dialog with design actions generating spontaneous design reactions within the surroundings Open Form is close to the original Taiwanese ways of developing the self organized and often ldquoil-legalrdquo communities These mi-crourban settlements are con-taining a high volume of Local Knowledge which we also be-lieve will start composting in Paracity when opening up the community development to the citizens

Centralized architectural con-trol is opened up in order to let nature including human nature to step in The life providing volume of Paracity is 11 exist-ence maximum highest possi-ble life in the given conditions

and more

CLT SKELETONParacity provides the skeleton but citizens bring in the flesh Design should not replace re-ality Flesh is More The skel-eton the primary structure of

Paracity is constructed out of 6 meters long (50x50 cm profile) cross laminated timber CLT sticks which are used to form 6x6x6 m cubes that are piled up to 16 stories high (8 cubes) The CLT primary structure has a fine earthquake performance and it is fire resistant The structural elements sticks with wood joints are prefab-ricated and transported to the Paracity Island on barges The construction work ndash the growing of the Paracity prima-ry organism can be manually done by residents in teams of by professional parasite con-structors The CLT structure is just a landscape on which citizens will attach their own

houses and gardens

ENVIROMENTAL TECHNOLOGYThe biourban growth of the Paracity is supported by high environmental technology which is mounted on barges These modular bio-vessels are attached to the Paracity ser-vice harbour and can be ad-justed according to the needs of the evolving urban organ-ism The post-industrial fleet of bio-vessels can travel along the Taipei river system and is

ready to start the biourban restoration process also from other hot-spots of the river city The environmental technology barges provide solutions for

bull Waste water treatment of Paracity and of the sur-rounding Taipei

bull Water purification The in-frastructural water circula-tion is originated from the polluted Danshui River

bull Sludge treatment for ferti-lizer and bio-energy

bull Closed circuit aquaculture

bull Recycling of construction waste

bull Recycling of organic waste for fertilizer and bio-ener-gy

The barges have no problem with the flooding river

EXISTENCE MAXIMUMParacity is a seed of the Third Generation City the organ-ic ruin of the industrial city (2G) The modular biourban organism is designed to grow following the rule of nature existence maximum The pri-mary structure can be grown by people and after Paracity

has reached the critical mass the life providing system of the CLT structure will start es-calating It will cross the river and start rooting on the flood plains Then it will cross the 12 meters high Taipei flood wall and grow gradually into the city Seeds of the Paracity will start rooting in the urban acu-puncture points of Taipei ille-gal community gardens urban farms abandoned cemeteries and waste-lands From these acupuncture points the Parac-ity will start growing following the covered irrigation systems such as the Liukong Channel and eventually the biourban or-ganism and the static city will find a balance the Third Gen-eration Taipei

PARASITE URBANISMParacity is living off the ma-terial streams from the sur-rounding Taipei Even the pol-luted river is a resource for this biourban intestine Parac-ity is Medieval medicine using leaches to cure the circulation Paracity is letting off the bad blood of Taipei and it uses it a resource In fact it makes money out of the process Of-ficially 37 of the Taipei City

waste water goes untreated to the river Paracity wants it all And it wants all the other ma-terials which the industrial city is regarding as ldquowasterdquo Parac-ity and modern Taipei live in a similar kind of a symbiosis as a slum and the city the urban nomads will clean the static city from its ldquowasterdquo only in Paracity the cleaning and recy-cling process is boosted up by high environmental technolo-gy In a sense the Paracity is a high-tech slum

BIO-ENERGYThe main energy source for the Paracity is bio-energy which is using both treated organic waste and sludge from Parac-ity and surrounding Taipei and especially biomass that is harvested around Paracity and on the flood banks of the Taipei rivers The fertile flood banks flood plains and storm water channels provide ideal cultivation areas for fast grow-ing biomass plantations The vegetation will be harvested by boats and then shipped to Paracity Bio-Energy Facility The growing of the biomass on the river banks will also ben-efit on the natural river resto-ration through root cleansing of sediment pollution and the

biomass will have a positive impact on the Taipei micro cli-mate and urban ecology

MediatorAfter rooting on the riverside and gaining a critical mass the Paracity will climb over the 12 meters high reinforced con-crete flood wall which is sepa-rating modern Taipei from the rivers and nature The flood wall will remain in the guts of the Paracity but the new struc-ture enables Taipei citizens to fluently reach the river Parac-ity will reunite the river reality and the urban fiction Parac-ity is a mediator between the modern city and nature

BIOCLIMATIC ARCHITECTUREParacity has a lot of holes gaps and nature in-between houses The system is ventilat-ing itself like a large scale bee-hive of post-industrial insects The different temperatures of the roofs gardens water bod-ies and shaded platforms will generate small winds between them and the hot roofs will start sucking in breeze from the cooler river Also the indi-vidual houses should follow the traditional principles of bi-

oclimatic architecture and not rely on mechanical air-condi-tioning

FREE FLOODINGParacity is based on free flood-ing The whole city is standing on stilts allowing the river to pulsate freely with the frequent typhoons and storm waters The environmental technology of the Paracity is mounted on barges which have no problem with the flooding either Actu-ally the Paracity is an organic architectural flood itself ready to cross the flood wall of Taipei and spread into the mechani-cal city

BIOURBAN RESTORATIONParacity is a positive organic tumour in the mechanical tis-sue of Taipei While it is leach-ing and processing the indus-trial and organic waste of the city it is gaining momentum in its growth and becomes more and more important to the static industrial urbanism Paracity is an alternative real-ity within the industrial devel-opment and will start treating the city the same ways as the urban acupuncture points of illegal community gardens and

urban farms of Taipei do today Paracity has the ability to be-come a network of biourban acupuncture tuning the whole industrial city towards the or-ganic ruining the industrialism on its way to become part of nature the Third Generation City

ORGANIC LAYERSThe biourbanism of the Parac-ity is as much landscape as it is architecture The totalitari-an landscape-architecture of Paracity includes organic lay-ers for natural water purifica-tion and treatment community gardening farming and bio-mass production as an energy source Infrastructure and ir-rigation water originates from the polluted Danshui river and will be both chemically and bi-ologically purified before being used in the farms gardens and houses of the community The chemically purified water gets pumped to the roof parks on the top level of the Paracity from where the gravity will cir-culate the water into the three dimensional irrigation sys-tems

ADAPTABILITYThe pilot-project of the Paraci-ty is designed in Taipei but the solution is developed to work in different locations around the world Paracity offers an alter-native for the Chinese strategic urban planning to start ecolog-ically harmonizing the grow-ing river cities of China And Paracity can be used as urban acupuncture for the emerging cities of China and elsewhere Paracity can grow along the Oshiwara chain of slums in Mumbai providing better liv-ing conditions cleaning up the Oshiwara River and more effectively treating the urban waste that is flooding in from the surrounding city Paracity can parachute into Nairobi and start growing from the fertile top-soil of the slums Paracity should grow into the favelas of Brazil and start celebrating the local knowledge of these organic communities Paracity is organic adaptable and wel-comes local knowledge The city is built by hands of a high diversity of different people

LOCAL KNOWLEDGEParacity is inspired by the Lo-cal Knowledge of Taipei the original Taiwanese urban ele-

ments that include a high level of self-made ldquoillegalrdquo archi-tecture self-organized com-munities extensive networks of self-organized community gardens and urban farms fluid nomadic ways of using the city communicative collective sub-conscious in community and urban scale feeling of domi-nating the no-manrsquos land by human nature and other forms of constructive anarchy The Paracity basically only pro-vides the primary structure the three dimensional landscape for the Local Knowledge to be attached and grow The prima-ry structure and the environ-mental technology solutions will remain pretty much the same no matter in which cul-ture the Paracity starts to grow but the real human layer of DIY architecture and gardens will follow the Local Knowledge of the respective culture and site Paracity is always site-specific and it is always local

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

ldquoWe need a recognized certification system that in-corporates our specificities and realities promotes the value of our forest products and ensures an equal share of benefits along the value chain Our stakehold-ers are motivated by the bottom-up approach keen to participate in the creation of their own certification system and wanting to ensure they understand their system once it is readyrdquo

Christine Nkene PAFC Cameroon

ldquoPrivate forest owners in Hungary view PEFC certifi-cation as their only affordable option and everyone including those already involved with other systems value PEFC for respecting our natural economic and social environment Legislative developments like the European Union Timber Regulation have also drawn the stakeholdersrsquo attention towards certificationrdquo

ldquoCommunity forestry is successful here with over 18000 community forestry user groups managing about 17 million ha of forest We have proven our-selves in forest protection

but there is a need to enhance our rural livelihood op-portunities through sustainable forest management Developing a PEFC-endorsed national forest certifica-tion scheme will help us to build recognition through-out the country on the potential for managing forests sustainablyrdquo

Ghan Shyam Pandey Green Foundation Nepal

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

OPEN FORMIn its growth Paracity is follow-ing the organic design meth-odology of Open Form (Os-car Hansen Svein Hatloy) in which community level design is viewed as an open dialog with design actions generating spontaneous design reactions within the surroundings Open Form is close to the original Taiwanese ways of developing the self organized and often ldquoil-legalrdquo communities These mi-crourban settlements are con-taining a high volume of Local Knowledge which we also be-lieve will start composting in Paracity when opening up the community development to the citizens

Centralized architectural con-trol is opened up in order to let nature including human nature to step in The life providing volume of Paracity is 11 exist-ence maximum highest possi-ble life in the given conditions

and more

CLT SKELETONParacity provides the skeleton but citizens bring in the flesh Design should not replace re-ality Flesh is More The skel-eton the primary structure of

Paracity is constructed out of 6 meters long (50x50 cm profile) cross laminated timber CLT sticks which are used to form 6x6x6 m cubes that are piled up to 16 stories high (8 cubes) The CLT primary structure has a fine earthquake performance and it is fire resistant The structural elements sticks with wood joints are prefab-ricated and transported to the Paracity Island on barges The construction work ndash the growing of the Paracity prima-ry organism can be manually done by residents in teams of by professional parasite con-structors The CLT structure is just a landscape on which citizens will attach their own

houses and gardens

ENVIROMENTAL TECHNOLOGYThe biourban growth of the Paracity is supported by high environmental technology which is mounted on barges These modular bio-vessels are attached to the Paracity ser-vice harbour and can be ad-justed according to the needs of the evolving urban organ-ism The post-industrial fleet of bio-vessels can travel along the Taipei river system and is

ready to start the biourban restoration process also from other hot-spots of the river city The environmental technology barges provide solutions for

bull Waste water treatment of Paracity and of the sur-rounding Taipei

bull Water purification The in-frastructural water circula-tion is originated from the polluted Danshui River

bull Sludge treatment for ferti-lizer and bio-energy

bull Closed circuit aquaculture

bull Recycling of construction waste

bull Recycling of organic waste for fertilizer and bio-ener-gy

The barges have no problem with the flooding river

EXISTENCE MAXIMUMParacity is a seed of the Third Generation City the organ-ic ruin of the industrial city (2G) The modular biourban organism is designed to grow following the rule of nature existence maximum The pri-mary structure can be grown by people and after Paracity

has reached the critical mass the life providing system of the CLT structure will start es-calating It will cross the river and start rooting on the flood plains Then it will cross the 12 meters high Taipei flood wall and grow gradually into the city Seeds of the Paracity will start rooting in the urban acu-puncture points of Taipei ille-gal community gardens urban farms abandoned cemeteries and waste-lands From these acupuncture points the Parac-ity will start growing following the covered irrigation systems such as the Liukong Channel and eventually the biourban or-ganism and the static city will find a balance the Third Gen-eration Taipei

PARASITE URBANISMParacity is living off the ma-terial streams from the sur-rounding Taipei Even the pol-luted river is a resource for this biourban intestine Parac-ity is Medieval medicine using leaches to cure the circulation Paracity is letting off the bad blood of Taipei and it uses it a resource In fact it makes money out of the process Of-ficially 37 of the Taipei City

waste water goes untreated to the river Paracity wants it all And it wants all the other ma-terials which the industrial city is regarding as ldquowasterdquo Parac-ity and modern Taipei live in a similar kind of a symbiosis as a slum and the city the urban nomads will clean the static city from its ldquowasterdquo only in Paracity the cleaning and recy-cling process is boosted up by high environmental technolo-gy In a sense the Paracity is a high-tech slum

BIO-ENERGYThe main energy source for the Paracity is bio-energy which is using both treated organic waste and sludge from Parac-ity and surrounding Taipei and especially biomass that is harvested around Paracity and on the flood banks of the Taipei rivers The fertile flood banks flood plains and storm water channels provide ideal cultivation areas for fast grow-ing biomass plantations The vegetation will be harvested by boats and then shipped to Paracity Bio-Energy Facility The growing of the biomass on the river banks will also ben-efit on the natural river resto-ration through root cleansing of sediment pollution and the

biomass will have a positive impact on the Taipei micro cli-mate and urban ecology

MediatorAfter rooting on the riverside and gaining a critical mass the Paracity will climb over the 12 meters high reinforced con-crete flood wall which is sepa-rating modern Taipei from the rivers and nature The flood wall will remain in the guts of the Paracity but the new struc-ture enables Taipei citizens to fluently reach the river Parac-ity will reunite the river reality and the urban fiction Parac-ity is a mediator between the modern city and nature

BIOCLIMATIC ARCHITECTUREParacity has a lot of holes gaps and nature in-between houses The system is ventilat-ing itself like a large scale bee-hive of post-industrial insects The different temperatures of the roofs gardens water bod-ies and shaded platforms will generate small winds between them and the hot roofs will start sucking in breeze from the cooler river Also the indi-vidual houses should follow the traditional principles of bi-

oclimatic architecture and not rely on mechanical air-condi-tioning

FREE FLOODINGParacity is based on free flood-ing The whole city is standing on stilts allowing the river to pulsate freely with the frequent typhoons and storm waters The environmental technology of the Paracity is mounted on barges which have no problem with the flooding either Actu-ally the Paracity is an organic architectural flood itself ready to cross the flood wall of Taipei and spread into the mechani-cal city

BIOURBAN RESTORATIONParacity is a positive organic tumour in the mechanical tis-sue of Taipei While it is leach-ing and processing the indus-trial and organic waste of the city it is gaining momentum in its growth and becomes more and more important to the static industrial urbanism Paracity is an alternative real-ity within the industrial devel-opment and will start treating the city the same ways as the urban acupuncture points of illegal community gardens and

urban farms of Taipei do today Paracity has the ability to be-come a network of biourban acupuncture tuning the whole industrial city towards the or-ganic ruining the industrialism on its way to become part of nature the Third Generation City

ORGANIC LAYERSThe biourbanism of the Parac-ity is as much landscape as it is architecture The totalitari-an landscape-architecture of Paracity includes organic lay-ers for natural water purifica-tion and treatment community gardening farming and bio-mass production as an energy source Infrastructure and ir-rigation water originates from the polluted Danshui river and will be both chemically and bi-ologically purified before being used in the farms gardens and houses of the community The chemically purified water gets pumped to the roof parks on the top level of the Paracity from where the gravity will cir-culate the water into the three dimensional irrigation sys-tems

ADAPTABILITYThe pilot-project of the Paraci-ty is designed in Taipei but the solution is developed to work in different locations around the world Paracity offers an alter-native for the Chinese strategic urban planning to start ecolog-ically harmonizing the grow-ing river cities of China And Paracity can be used as urban acupuncture for the emerging cities of China and elsewhere Paracity can grow along the Oshiwara chain of slums in Mumbai providing better liv-ing conditions cleaning up the Oshiwara River and more effectively treating the urban waste that is flooding in from the surrounding city Paracity can parachute into Nairobi and start growing from the fertile top-soil of the slums Paracity should grow into the favelas of Brazil and start celebrating the local knowledge of these organic communities Paracity is organic adaptable and wel-comes local knowledge The city is built by hands of a high diversity of different people

LOCAL KNOWLEDGEParacity is inspired by the Lo-cal Knowledge of Taipei the original Taiwanese urban ele-

ments that include a high level of self-made ldquoillegalrdquo archi-tecture self-organized com-munities extensive networks of self-organized community gardens and urban farms fluid nomadic ways of using the city communicative collective sub-conscious in community and urban scale feeling of domi-nating the no-manrsquos land by human nature and other forms of constructive anarchy The Paracity basically only pro-vides the primary structure the three dimensional landscape for the Local Knowledge to be attached and grow The prima-ry structure and the environ-mental technology solutions will remain pretty much the same no matter in which cul-ture the Paracity starts to grow but the real human layer of DIY architecture and gardens will follow the Local Knowledge of the respective culture and site Paracity is always site-specific and it is always local

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ture the Peoplersquos Architecture or Weak Architecture The theory of urban acupuncture suggests that scores of small-scale less costly and localized projects is what cit-ies need in order to recover and re-new themselves

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Modernismi naumlkee kaupun-gin koneena ndash biourbanis-mille kaupunki on organismi Modernistisessa kaupunki-suunnittelussa joka on ollut vallitseva suunnittelupara-digma viimeiset 70-80 vuotta on vakavia puutteita joihin biourbaani kaupunkisuunnit-telu vastaa Paracity tarjoaa biourbaaneja suunnittelurat-kaisuja kaumlytaumlnnoumlssauml

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

OPEN FORMIn its growth Paracity is follow-ing the organic design meth-odology of Open Form (Os-car Hansen Svein Hatloy) in which community level design is viewed as an open dialog with design actions generating spontaneous design reactions within the surroundings Open Form is close to the original Taiwanese ways of developing the self organized and often ldquoil-legalrdquo communities These mi-crourban settlements are con-taining a high volume of Local Knowledge which we also be-lieve will start composting in Paracity when opening up the community development to the citizens

Centralized architectural con-trol is opened up in order to let nature including human nature to step in The life providing volume of Paracity is 11 exist-ence maximum highest possi-ble life in the given conditions

and more

CLT SKELETONParacity provides the skeleton but citizens bring in the flesh Design should not replace re-ality Flesh is More The skel-eton the primary structure of

Paracity is constructed out of 6 meters long (50x50 cm profile) cross laminated timber CLT sticks which are used to form 6x6x6 m cubes that are piled up to 16 stories high (8 cubes) The CLT primary structure has a fine earthquake performance and it is fire resistant The structural elements sticks with wood joints are prefab-ricated and transported to the Paracity Island on barges The construction work ndash the growing of the Paracity prima-ry organism can be manually done by residents in teams of by professional parasite con-structors The CLT structure is just a landscape on which citizens will attach their own

houses and gardens

ENVIROMENTAL TECHNOLOGYThe biourban growth of the Paracity is supported by high environmental technology which is mounted on barges These modular bio-vessels are attached to the Paracity ser-vice harbour and can be ad-justed according to the needs of the evolving urban organ-ism The post-industrial fleet of bio-vessels can travel along the Taipei river system and is

ready to start the biourban restoration process also from other hot-spots of the river city The environmental technology barges provide solutions for

bull Waste water treatment of Paracity and of the sur-rounding Taipei

bull Water purification The in-frastructural water circula-tion is originated from the polluted Danshui River

bull Sludge treatment for ferti-lizer and bio-energy

bull Closed circuit aquaculture

bull Recycling of construction waste

bull Recycling of organic waste for fertilizer and bio-ener-gy

The barges have no problem with the flooding river

EXISTENCE MAXIMUMParacity is a seed of the Third Generation City the organ-ic ruin of the industrial city (2G) The modular biourban organism is designed to grow following the rule of nature existence maximum The pri-mary structure can be grown by people and after Paracity

has reached the critical mass the life providing system of the CLT structure will start es-calating It will cross the river and start rooting on the flood plains Then it will cross the 12 meters high Taipei flood wall and grow gradually into the city Seeds of the Paracity will start rooting in the urban acu-puncture points of Taipei ille-gal community gardens urban farms abandoned cemeteries and waste-lands From these acupuncture points the Parac-ity will start growing following the covered irrigation systems such as the Liukong Channel and eventually the biourban or-ganism and the static city will find a balance the Third Gen-eration Taipei

PARASITE URBANISMParacity is living off the ma-terial streams from the sur-rounding Taipei Even the pol-luted river is a resource for this biourban intestine Parac-ity is Medieval medicine using leaches to cure the circulation Paracity is letting off the bad blood of Taipei and it uses it a resource In fact it makes money out of the process Of-ficially 37 of the Taipei City

waste water goes untreated to the river Paracity wants it all And it wants all the other ma-terials which the industrial city is regarding as ldquowasterdquo Parac-ity and modern Taipei live in a similar kind of a symbiosis as a slum and the city the urban nomads will clean the static city from its ldquowasterdquo only in Paracity the cleaning and recy-cling process is boosted up by high environmental technolo-gy In a sense the Paracity is a high-tech slum

BIO-ENERGYThe main energy source for the Paracity is bio-energy which is using both treated organic waste and sludge from Parac-ity and surrounding Taipei and especially biomass that is harvested around Paracity and on the flood banks of the Taipei rivers The fertile flood banks flood plains and storm water channels provide ideal cultivation areas for fast grow-ing biomass plantations The vegetation will be harvested by boats and then shipped to Paracity Bio-Energy Facility The growing of the biomass on the river banks will also ben-efit on the natural river resto-ration through root cleansing of sediment pollution and the

biomass will have a positive impact on the Taipei micro cli-mate and urban ecology

MediatorAfter rooting on the riverside and gaining a critical mass the Paracity will climb over the 12 meters high reinforced con-crete flood wall which is sepa-rating modern Taipei from the rivers and nature The flood wall will remain in the guts of the Paracity but the new struc-ture enables Taipei citizens to fluently reach the river Parac-ity will reunite the river reality and the urban fiction Parac-ity is a mediator between the modern city and nature

BIOCLIMATIC ARCHITECTUREParacity has a lot of holes gaps and nature in-between houses The system is ventilat-ing itself like a large scale bee-hive of post-industrial insects The different temperatures of the roofs gardens water bod-ies and shaded platforms will generate small winds between them and the hot roofs will start sucking in breeze from the cooler river Also the indi-vidual houses should follow the traditional principles of bi-

oclimatic architecture and not rely on mechanical air-condi-tioning

FREE FLOODINGParacity is based on free flood-ing The whole city is standing on stilts allowing the river to pulsate freely with the frequent typhoons and storm waters The environmental technology of the Paracity is mounted on barges which have no problem with the flooding either Actu-ally the Paracity is an organic architectural flood itself ready to cross the flood wall of Taipei and spread into the mechani-cal city

BIOURBAN RESTORATIONParacity is a positive organic tumour in the mechanical tis-sue of Taipei While it is leach-ing and processing the indus-trial and organic waste of the city it is gaining momentum in its growth and becomes more and more important to the static industrial urbanism Paracity is an alternative real-ity within the industrial devel-opment and will start treating the city the same ways as the urban acupuncture points of illegal community gardens and

urban farms of Taipei do today Paracity has the ability to be-come a network of biourban acupuncture tuning the whole industrial city towards the or-ganic ruining the industrialism on its way to become part of nature the Third Generation City

ORGANIC LAYERSThe biourbanism of the Parac-ity is as much landscape as it is architecture The totalitari-an landscape-architecture of Paracity includes organic lay-ers for natural water purifica-tion and treatment community gardening farming and bio-mass production as an energy source Infrastructure and ir-rigation water originates from the polluted Danshui river and will be both chemically and bi-ologically purified before being used in the farms gardens and houses of the community The chemically purified water gets pumped to the roof parks on the top level of the Paracity from where the gravity will cir-culate the water into the three dimensional irrigation sys-tems

ADAPTABILITYThe pilot-project of the Paraci-ty is designed in Taipei but the solution is developed to work in different locations around the world Paracity offers an alter-native for the Chinese strategic urban planning to start ecolog-ically harmonizing the grow-ing river cities of China And Paracity can be used as urban acupuncture for the emerging cities of China and elsewhere Paracity can grow along the Oshiwara chain of slums in Mumbai providing better liv-ing conditions cleaning up the Oshiwara River and more effectively treating the urban waste that is flooding in from the surrounding city Paracity can parachute into Nairobi and start growing from the fertile top-soil of the slums Paracity should grow into the favelas of Brazil and start celebrating the local knowledge of these organic communities Paracity is organic adaptable and wel-comes local knowledge The city is built by hands of a high diversity of different people

LOCAL KNOWLEDGEParacity is inspired by the Lo-cal Knowledge of Taipei the original Taiwanese urban ele-

ments that include a high level of self-made ldquoillegalrdquo archi-tecture self-organized com-munities extensive networks of self-organized community gardens and urban farms fluid nomadic ways of using the city communicative collective sub-conscious in community and urban scale feeling of domi-nating the no-manrsquos land by human nature and other forms of constructive anarchy The Paracity basically only pro-vides the primary structure the three dimensional landscape for the Local Knowledge to be attached and grow The prima-ry structure and the environ-mental technology solutions will remain pretty much the same no matter in which cul-ture the Paracity starts to grow but the real human layer of DIY architecture and gardens will follow the Local Knowledge of the respective culture and site Paracity is always site-specific and it is always local

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ture the Peoplersquos Architecture or Weak Architecture The theory of urban acupuncture suggests that scores of small-scale less costly and localized projects is what cit-ies need in order to recover and re-new themselves

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

OPEN FORMIn its growth Paracity is follow-ing the organic design meth-odology of Open Form (Os-car Hansen Svein Hatloy) in which community level design is viewed as an open dialog with design actions generating spontaneous design reactions within the surroundings Open Form is close to the original Taiwanese ways of developing the self organized and often ldquoil-legalrdquo communities These mi-crourban settlements are con-taining a high volume of Local Knowledge which we also be-lieve will start composting in Paracity when opening up the community development to the citizens

Centralized architectural con-trol is opened up in order to let nature including human nature to step in The life providing volume of Paracity is 11 exist-ence maximum highest possi-ble life in the given conditions

and more

CLT SKELETONParacity provides the skeleton but citizens bring in the flesh Design should not replace re-ality Flesh is More The skel-eton the primary structure of

Paracity is constructed out of 6 meters long (50x50 cm profile) cross laminated timber CLT sticks which are used to form 6x6x6 m cubes that are piled up to 16 stories high (8 cubes) The CLT primary structure has a fine earthquake performance and it is fire resistant The structural elements sticks with wood joints are prefab-ricated and transported to the Paracity Island on barges The construction work ndash the growing of the Paracity prima-ry organism can be manually done by residents in teams of by professional parasite con-structors The CLT structure is just a landscape on which citizens will attach their own

houses and gardens

ENVIROMENTAL TECHNOLOGYThe biourban growth of the Paracity is supported by high environmental technology which is mounted on barges These modular bio-vessels are attached to the Paracity ser-vice harbour and can be ad-justed according to the needs of the evolving urban organ-ism The post-industrial fleet of bio-vessels can travel along the Taipei river system and is

ready to start the biourban restoration process also from other hot-spots of the river city The environmental technology barges provide solutions for

bull Waste water treatment of Paracity and of the sur-rounding Taipei

bull Water purification The in-frastructural water circula-tion is originated from the polluted Danshui River

bull Sludge treatment for ferti-lizer and bio-energy

bull Closed circuit aquaculture

bull Recycling of construction waste

bull Recycling of organic waste for fertilizer and bio-ener-gy

The barges have no problem with the flooding river

EXISTENCE MAXIMUMParacity is a seed of the Third Generation City the organ-ic ruin of the industrial city (2G) The modular biourban organism is designed to grow following the rule of nature existence maximum The pri-mary structure can be grown by people and after Paracity

has reached the critical mass the life providing system of the CLT structure will start es-calating It will cross the river and start rooting on the flood plains Then it will cross the 12 meters high Taipei flood wall and grow gradually into the city Seeds of the Paracity will start rooting in the urban acu-puncture points of Taipei ille-gal community gardens urban farms abandoned cemeteries and waste-lands From these acupuncture points the Parac-ity will start growing following the covered irrigation systems such as the Liukong Channel and eventually the biourban or-ganism and the static city will find a balance the Third Gen-eration Taipei

PARASITE URBANISMParacity is living off the ma-terial streams from the sur-rounding Taipei Even the pol-luted river is a resource for this biourban intestine Parac-ity is Medieval medicine using leaches to cure the circulation Paracity is letting off the bad blood of Taipei and it uses it a resource In fact it makes money out of the process Of-ficially 37 of the Taipei City

waste water goes untreated to the river Paracity wants it all And it wants all the other ma-terials which the industrial city is regarding as ldquowasterdquo Parac-ity and modern Taipei live in a similar kind of a symbiosis as a slum and the city the urban nomads will clean the static city from its ldquowasterdquo only in Paracity the cleaning and recy-cling process is boosted up by high environmental technolo-gy In a sense the Paracity is a high-tech slum

BIO-ENERGYThe main energy source for the Paracity is bio-energy which is using both treated organic waste and sludge from Parac-ity and surrounding Taipei and especially biomass that is harvested around Paracity and on the flood banks of the Taipei rivers The fertile flood banks flood plains and storm water channels provide ideal cultivation areas for fast grow-ing biomass plantations The vegetation will be harvested by boats and then shipped to Paracity Bio-Energy Facility The growing of the biomass on the river banks will also ben-efit on the natural river resto-ration through root cleansing of sediment pollution and the

biomass will have a positive impact on the Taipei micro cli-mate and urban ecology

MediatorAfter rooting on the riverside and gaining a critical mass the Paracity will climb over the 12 meters high reinforced con-crete flood wall which is sepa-rating modern Taipei from the rivers and nature The flood wall will remain in the guts of the Paracity but the new struc-ture enables Taipei citizens to fluently reach the river Parac-ity will reunite the river reality and the urban fiction Parac-ity is a mediator between the modern city and nature

BIOCLIMATIC ARCHITECTUREParacity has a lot of holes gaps and nature in-between houses The system is ventilat-ing itself like a large scale bee-hive of post-industrial insects The different temperatures of the roofs gardens water bod-ies and shaded platforms will generate small winds between them and the hot roofs will start sucking in breeze from the cooler river Also the indi-vidual houses should follow the traditional principles of bi-

oclimatic architecture and not rely on mechanical air-condi-tioning

FREE FLOODINGParacity is based on free flood-ing The whole city is standing on stilts allowing the river to pulsate freely with the frequent typhoons and storm waters The environmental technology of the Paracity is mounted on barges which have no problem with the flooding either Actu-ally the Paracity is an organic architectural flood itself ready to cross the flood wall of Taipei and spread into the mechani-cal city

BIOURBAN RESTORATIONParacity is a positive organic tumour in the mechanical tis-sue of Taipei While it is leach-ing and processing the indus-trial and organic waste of the city it is gaining momentum in its growth and becomes more and more important to the static industrial urbanism Paracity is an alternative real-ity within the industrial devel-opment and will start treating the city the same ways as the urban acupuncture points of illegal community gardens and

urban farms of Taipei do today Paracity has the ability to be-come a network of biourban acupuncture tuning the whole industrial city towards the or-ganic ruining the industrialism on its way to become part of nature the Third Generation City

ORGANIC LAYERSThe biourbanism of the Parac-ity is as much landscape as it is architecture The totalitari-an landscape-architecture of Paracity includes organic lay-ers for natural water purifica-tion and treatment community gardening farming and bio-mass production as an energy source Infrastructure and ir-rigation water originates from the polluted Danshui river and will be both chemically and bi-ologically purified before being used in the farms gardens and houses of the community The chemically purified water gets pumped to the roof parks on the top level of the Paracity from where the gravity will cir-culate the water into the three dimensional irrigation sys-tems

ADAPTABILITYThe pilot-project of the Paraci-ty is designed in Taipei but the solution is developed to work in different locations around the world Paracity offers an alter-native for the Chinese strategic urban planning to start ecolog-ically harmonizing the grow-ing river cities of China And Paracity can be used as urban acupuncture for the emerging cities of China and elsewhere Paracity can grow along the Oshiwara chain of slums in Mumbai providing better liv-ing conditions cleaning up the Oshiwara River and more effectively treating the urban waste that is flooding in from the surrounding city Paracity can parachute into Nairobi and start growing from the fertile top-soil of the slums Paracity should grow into the favelas of Brazil and start celebrating the local knowledge of these organic communities Paracity is organic adaptable and wel-comes local knowledge The city is built by hands of a high diversity of different people

LOCAL KNOWLEDGEParacity is inspired by the Lo-cal Knowledge of Taipei the original Taiwanese urban ele-

ments that include a high level of self-made ldquoillegalrdquo archi-tecture self-organized com-munities extensive networks of self-organized community gardens and urban farms fluid nomadic ways of using the city communicative collective sub-conscious in community and urban scale feeling of domi-nating the no-manrsquos land by human nature and other forms of constructive anarchy The Paracity basically only pro-vides the primary structure the three dimensional landscape for the Local Knowledge to be attached and grow The prima-ry structure and the environ-mental technology solutions will remain pretty much the same no matter in which cul-ture the Paracity starts to grow but the real human layer of DIY architecture and gardens will follow the Local Knowledge of the respective culture and site Paracity is always site-specific and it is always local

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

The legitimation and restoration process (2003-2010) of Treasure Hill is now completed Some of the old community has moved back and some have moved away Now the next step is to inject new blood into the hill The organism is ready and willing to live Missis Chen is still in charge

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

biomass will have a positive impact on the Taipei micro cli-mate and urban ecology

MediatorAfter rooting on the riverside and gaining a critical mass the Paracity will climb over the 12 meters high reinforced con-crete flood wall which is sepa-rating modern Taipei from the rivers and nature The flood wall will remain in the guts of the Paracity but the new struc-ture enables Taipei citizens to fluently reach the river Parac-ity will reunite the river reality and the urban fiction Parac-ity is a mediator between the modern city and nature

BIOCLIMATIC ARCHITECTUREParacity has a lot of holes gaps and nature in-between houses The system is ventilat-ing itself like a large scale bee-hive of post-industrial insects The different temperatures of the roofs gardens water bod-ies and shaded platforms will generate small winds between them and the hot roofs will start sucking in breeze from the cooler river Also the indi-vidual houses should follow the traditional principles of bi-

oclimatic architecture and not rely on mechanical air-condi-tioning

FREE FLOODINGParacity is based on free flood-ing The whole city is standing on stilts allowing the river to pulsate freely with the frequent typhoons and storm waters The environmental technology of the Paracity is mounted on barges which have no problem with the flooding either Actu-ally the Paracity is an organic architectural flood itself ready to cross the flood wall of Taipei and spread into the mechani-cal city

BIOURBAN RESTORATIONParacity is a positive organic tumour in the mechanical tis-sue of Taipei While it is leach-ing and processing the indus-trial and organic waste of the city it is gaining momentum in its growth and becomes more and more important to the static industrial urbanism Paracity is an alternative real-ity within the industrial devel-opment and will start treating the city the same ways as the urban acupuncture points of illegal community gardens and

urban farms of Taipei do today Paracity has the ability to be-come a network of biourban acupuncture tuning the whole industrial city towards the or-ganic ruining the industrialism on its way to become part of nature the Third Generation City

ORGANIC LAYERSThe biourbanism of the Parac-ity is as much landscape as it is architecture The totalitari-an landscape-architecture of Paracity includes organic lay-ers for natural water purifica-tion and treatment community gardening farming and bio-mass production as an energy source Infrastructure and ir-rigation water originates from the polluted Danshui river and will be both chemically and bi-ologically purified before being used in the farms gardens and houses of the community The chemically purified water gets pumped to the roof parks on the top level of the Paracity from where the gravity will cir-culate the water into the three dimensional irrigation sys-tems

ADAPTABILITYThe pilot-project of the Paraci-ty is designed in Taipei but the solution is developed to work in different locations around the world Paracity offers an alter-native for the Chinese strategic urban planning to start ecolog-ically harmonizing the grow-ing river cities of China And Paracity can be used as urban acupuncture for the emerging cities of China and elsewhere Paracity can grow along the Oshiwara chain of slums in Mumbai providing better liv-ing conditions cleaning up the Oshiwara River and more effectively treating the urban waste that is flooding in from the surrounding city Paracity can parachute into Nairobi and start growing from the fertile top-soil of the slums Paracity should grow into the favelas of Brazil and start celebrating the local knowledge of these organic communities Paracity is organic adaptable and wel-comes local knowledge The city is built by hands of a high diversity of different people

LOCAL KNOWLEDGEParacity is inspired by the Lo-cal Knowledge of Taipei the original Taiwanese urban ele-

ments that include a high level of self-made ldquoillegalrdquo archi-tecture self-organized com-munities extensive networks of self-organized community gardens and urban farms fluid nomadic ways of using the city communicative collective sub-conscious in community and urban scale feeling of domi-nating the no-manrsquos land by human nature and other forms of constructive anarchy The Paracity basically only pro-vides the primary structure the three dimensional landscape for the Local Knowledge to be attached and grow The prima-ry structure and the environ-mental technology solutions will remain pretty much the same no matter in which cul-ture the Paracity starts to grow but the real human layer of DIY architecture and gardens will follow the Local Knowledge of the respective culture and site Paracity is always site-specific and it is always local

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ture the Peoplersquos Architecture or Weak Architecture The theory of urban acupuncture suggests that scores of small-scale less costly and localized projects is what cit-ies need in order to recover and re-new themselves

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Modernismi naumlkee kaupun-gin koneena ndash biourbanis-mille kaupunki on organismi Modernistisessa kaupunki-suunnittelussa joka on ollut vallitseva suunnittelupara-digma viimeiset 70-80 vuotta on vakavia puutteita joihin biourbaani kaupunkisuunnit-telu vastaa Paracity tarjoaa biourbaaneja suunnittelurat-kaisuja kaumlytaumlnnoumlssauml

Biourbanismille ihminen ei ole kone Ihminen on organismi kaupunki on organismi kau-punkien verkosto on orga-nismi Kaupunki muodostuu useista toisiinsa dynaamisesti linkittyneistauml kerroksista mut-ta linkit eivaumlt ole suoraviivaisia Kaupungin orgaaninen raken-ne aiheuttaa sen ettauml kaupun-gin kehittyminen ja ihmisten toiminta kaupungissa ei ole ennustettavissa Kaupunki ja sen ihmiset ovat rationaalisia vain osittain sattuma on kont-rollia arvokkaampaa Tarpeet ja halut vaihtelevat niin per-soonien vaumllillauml kuin ajallisesti Emme tiedauml miltauml maailma naumlyttaumlauml 2020-luvulla Kuinka voisimme tietaumlauml millaisessa kaupungissa ihmiset haluavat silloin elaumlauml Kaupungin taumlytyy pystyauml korjaamaan itsensauml biologisen organismin tavoin

Biourbaani kaupunki (kuten Paracity) tarjoaa rungon johon kaupunki voi kasvaa Paracity on kaupungin luuranko joka antaa tuen elaumlmaumllle Se ei nojaa arkkitehtien ja kaupunkisuun-nittelijoiden taitoon ennakoida tulevaa Sen sijaan Paracityn pohjana on paikallinen traditio Taipeissa elaumlauml edelleen vah-va perinne rakentaa ja viljellauml urbaanin kaupungin jakojaumlaumln-noumlsalueita Taipeissa kaikkiin

COMMEDIA

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

from Andrei Tarkowskirsquos Stalker (1979 Mosfilm)

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

Text Marco Casagrande First generation city was the human settlement in straight connection with nature and dependent on nature The fertile and rich Taipei basin provided a fruitful environment for such a settlement The rivers were full of fish and good for transportation and the mountains protected the farmed plains from the straight-est hits of the frequent typhoons

The second generation city is the industrial city Industri-alism granted the citizens in-dependence from nature ndash a mechanical environment could provide everything needed for hu-mans Nature was seen as some-thing unnecessary or as some-thing hostile ndash it was walled away from the mechanical reality

Third Generation City is the or-ganic ruin of the industrial city The community gardens of Taipei are fragments of the third generation urbanism when they exist togeth-er with the industrial surround-ings Local Knowledge is present in the city and this is where Ruin Academy focuses its research Among the urban gardeners are the local knowledge professors of Taipei Third Generation City is true when the city recognizes its local knowledge and allows itself to be part of nature

The way towards the Third Gen-eration City is a process of be-coming a learning and healing or-ganization and to reconnect the

urbanized collective conscious with nature In Taipei the wall be-tween the city and the river must be gone This requires a total transformation from the city infra-structure and the centralized pow-er bureaucracy Citizens on their behalf are ready and are breaking the industrial city by themselves already Local knowledge is oper-ating independently from the offi-cial city and is providing punctu-al third generation surroundings within the industrial city and by doing that providing self organ-ized urban acupuncture for the stiff official mechanism

The weak signals of the unofficial collective conscious should be recognized as the futures emerg-ing issues futures that are already present in Taipei The official city should learn how to enjoy acu-puncture how to give up industri-al control in order to let nature to step in The local knowledge based transformation layer of Taipei is happening from inside the city and it is happening through self organized punctual interventions These interventions are driven by small scale businesses and alter-native economies benefiting from the fertile land of the Taipei Basin and of leaching from the material and energy streams of the official city This acupuncture is making the city weaker softer and readier for a larger change

RUIN ACADEMY

The Ruin Academy (Taipei 2010-2012) is set to re-think the indus-

trial city and the relationship be-tween the modern man and nature in the urbanized Taipei Basin It is looking from the local knowledge for the seeds of the Third Gener-ation City

Ruin is when man-made has be-come part of nature This is the subconscious desire of the indus-trial city and the collective trau-ma of the modern man Taipei is currently presenting the most ad-vanced industrial co-existence of a modern city and uncontrollable organic anarchy nature including human nature is pushing through the industrial surface and turning the city towards the organic ac-cording to a post-human design and ecological sensibility To un-derstand this force the reinforced and divided academic disciplines are of no use Neither is central-ized politics providing any tools Communication needs to find an-other way

Ruin Academy has focused its re-search on the unofficial life-pro-viding systems within the official mechanical city These sponta-neous and citizen-generated sys-tems are constantly ruining the official Taipei These are systems that are through punctual inter-ventions fermenting and com-posting the city From the organic top-soil produced by these com-posts will emerge the Third Gen-eration City the organic ruin of the industrial city an organic machine In Erik Swyngedouwrsquos terms rdquoNa-ture and society are in this way combined to form an urban po-

litical ecology a hybrid an urban cyborg that combines the pow-ers of nature with those of class gender and ethnic relationsrdquo The smelliest parts of unofficial Taipei contain the highest level of ener-gy and life still in connection with nature at the same time the offi-cial industrialism aims for a ster-ile and fully controlled condition This brings to mind Andrei Tark-ovskyrsquos maxim in Stalker ldquoWhen a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never winrdquo These urban composts are the corners that are maintaining the essence of the Local Knowledge a constructive interaction of na-ture and human nature in the built human environment This local knowledge is suggesting the ways of the ruining processes for Taipei towards the Third Generation City

Different disciplines of art and science are meeting in the Ruin Academy following the multidis-ciplinary research + design meth-odology of the Aalto Universityrsquos SGT Sustainable Global Technol-ogies centre Cross-disciplinary knowledge building has proven vital on the research of the Third Generation City Ruin Academy co-operates with the architec-ture department of the Tamkang University sociology department of the National Taiwan Universi-ty and with the SGT centre of the Aalto University Besides these

teams and individuals have been joining the work from various dif-ferent backgrounds Ruin Acade-my is unofficial pliant and weak in contrast to academic strength and hardness The Ruin Acade-my is a basic shelter for academic squatting stripped down from dis-ciplinary focusing and institution-al strength Most important is the connection to the Local Knowl-edge the site-specific wisdom of sustainable human presence in the Taipei Basin This knowledge seems to be in straight connec-tion with the collective memory of the First Generation City when the built human environment was de-pendent on nature and dominated by nature The Local Knowledge is the driving force for the organic penetrations through the industri-al layer of the Taipei Basin today Local Knowledge is the force tun-ing the city towards the organic Our communication center is the public sauna on the 5th floor of the Ruin Academy building4

We are looking for the seeds of the Third Generation City

What are the processes that are ruining the industrial Taipei turning it towards the organic third gener-ation city

What are the systems that are bringing life into the modern ma-chine

What is the life-force Chi that keeps the city alive and how can this Chi be negotiated with by means of Urban Acupuncture

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

ldquoCommunity forestry is successful here with over 18000 community forestry user groups managing about 17 million ha of forest We have proven our-selves in forest protection

but there is a need to enhance our rural livelihood op-portunities through sustainable forest management Developing a PEFC-endorsed national forest certifica-tion scheme will help us to build recognition through-out the country on the potential for managing forests sustainablyrdquo

Ghan Shyam Pandey Green Foundation Nepal

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

THE ELEMENTS OF THE THIRD GENERATION TAIPEI

1 Urban Acupuncture

Urban acupuncture is charac-terized by punctual interventions through the official surface of the city which aim to establish con-tact between the urban collective conscious and the life-providing systems of nature including hu-man nature The networks of ille-gal community gardens and ur-ban farms of Taipei present a fine example of urban acupuncture These gardens are the urban acu-puncture needles that manipulate and manifest the collective un-derlying organic Chi of the indus-trial city and turn the mechanical city towards an organic machine The spontaneous unofficial and self-organized community gar-dens are strong representations of anarchy through gardening The collective gardens are reflections of life world vs the surrounding city as the system world

2Illegal Architecture

The Instant Taipei is self-made architecture using the official city as a growing platform and energy sourceattaching itself like a par-asite in order to leach electricity and water The illegal architecture is so widespread and deep rooted as a culture in the Taiwanese city-scape that we could almost speak about another city on top of the ldquoofficialrdquo Taipei a parallel cityndashor a Para-City This DIY built human environment is tied directly to hu-man nature and motivated by ba-sic human instinct and mandated only by desire and availability Par-adoxically the illegal settlements such as Treasure Hill are living in a more balanced relationship with the natural environment

2 Urban Nomad

The urban nomad is the antithe-sis of Walter Benjaminrsquos flacircneur who is numb and absent in the capital-driven urban surround-ings The urban nomad is on the move harvesting and trapping in a city that he views as a landscape wherein seasons and energy con-centrations are constantly chang-ing The urban nomad can oper-ate alone or in larger camp-like concentrations such as the night markets He is faster and light-er than the official control mech-anism of the city which tries to prevent him from operating Be-sides trading the urban nomads are also harvesting the city of its trash and left-over goods for re-cycling This hit-and-run unofficial economy is leaching on the steady material streams of the structur-al city and is presenting a form of street-level anarchy through busi-ness exchange A series of activi-ties are on the move or popping up and disappearing in Taipei these include the night markets un-der-bridge activities street ven-dors spontaneous karaoke gam-

bling puppet theatre massage barber monks beetle-nut booths and even moving godsndashall very sensitive to the urban energy flows and hot-spots of urban ac-upuncture

4 River Urbanism

Taipei (1G) exists because of the river and the fertile flood plains The industrial city (2G) claimed independence from nature and turned the river into an industri-al sewage site A reinforced con-crete wall 12 meters high was constructed in-between the built human environment and the riv-er nature Third Generation City aims to reunite the river and city through the natural restoration of the river environment The river shall run as an ecological corridor through a city that is pulsating to-gether with its hydraulics The city will be re-developed from the view point of the river Local knowledge still remembers the time when the water of the rivers was drinkable and people washed themselves in the rivers Every family had a row-ing boat and the river was full of harvest This is still a living mem-ory for some in Taipei but for the industrial generations the river has become a fiction

The Phoenix bird has not yet come and the River has not yet revealed its divine nature this is the end of me - Confucius

5 Ultra-Ruin

Ruin is when man-made has be-come part of nature The ruining processes of Taipei are keeping the city alive A weed will root into a crack in the asphalt and eventu-ally ruin the city The crack is the acupuncture point and the weed is the needle The mechanical sur-face of Taipei is dotted with ruins and holes reflecting a larger vision of an organic machine the organ-ic ruin of the industrial city People are constantly ruining the totali-tarian control architecture of the industrial mind which they sub-consciously feel as a threat to the human nature To understand the dynamics of the ruining processes of a city is essential for the grow-ing of the Third Generation built human environment Treasure Hill is a high-density ruin a frag-ment of the Third Generation City In the settlement the same space is shared by people and jungle and the complex three-dimensional power balances between the dif-ferent species including humans is delicately changing day by day Treasure Hill also lives on a flood bank and does not view the river as a threat It is inhabited by urban nomads who are harvesting the surrounding city The whole set-tlement is an urban acupuncture needle for Taipei

Local knowledge is an element that is pushing through all the lay-ers of the 3G City a connection between the modern man and na-

ture Following Fritz Lang in Me-tropolis ldquoThe mediator between the head and the hands must be the heartrdquo Local knowledge is the mediator that is tying the Third Generation citizen with nature and which operates as the subcon-scious natural agent on the col-lective conscious of the civilized man

BIOURBAN ACUPUNCTURE

Urban acupuncture is an urban environmentalism theory which combines urban design with tra-ditional Chinese medical theo-ry of acupuncture This process uses small-scale interventions to transform the larger urban con-text Sites are selected through an aggregate analysis of social eco-nomic and ecological factors and developed through a dialogue be-tween designers and the commu-nity Acupuncture relieves stress in the body urban acupuncture re-lieves stress in the environment Urban acupuncture produces small-scale but socially catalytic interventions into the urban fabric

This strategy views cities as liv-ing breathing organisms and pin-points areas in need of repair Sus-tainable projects then serve as needles that revitalize the whole by healing the parts By perceiving the city as a living creature thor-oughly intertwined ldquourban acu-puncturerdquo promotes communitar-ian machinery and sets localized nucleus ―similar to the human bodyrsquos meridians Satellite tech-nology networks and collective in-telligence theories all used to sur-gically and selectively intervene on the nodes that have the biggest potential to regenerate

Originally coined by Barcelonan architect and urbanist Manuel de Sola Morales the term has been re-cently championed and developed further by Finnish architect and social theorist Marco Casagrande this school of thought eschews massive urban renewal projects in favour a of more localised and community approach that in an era of constrained budgets and limited resources could demo-cratically and cheaply offer a res-pite to urban dwellers Casagrande views cities as complex energy or-ganisms in which different over-lapping layers of energy flows are determining the actions of the citizens as well as the develop-ment of the city By mixing envi-ronmentalism and urban design Casagrande is developing meth-ods of punctual manipulation of the urban energy flows in order to create an ecologically sustain-able urban development towards the so-called 3rd Generation City (post-industrial city) The theory is developed in the Tamkang Univer-sity of Taiwan and at independent multidisciplinary research center Ruin Academy With focus on en-vironmentalism and urban design Casagrande defines urban acu-puncture as a design tool where

punctual manipulations contribute to creating sustainable urban de-velopment such as the commu-nity gardens and urban farms in Taipei

Casagrande describes urban acu-puncture as

[a] cross-over architectural ma-nipulation of the collective sen-suous intellect of a city City is viewed as multi-dimensional sen-sitive energy-organism a living environment Urban acupuncture aims into a touch with this nature

And Sensitivity to understand the energy flows of the collective chi beneath the visual city and react-ing on the hot-spots of this chi Ar-chitecture is in the position to pro-duce the acupuncture needles for the urban chi

And A weed will root into the smallest crack in the asphalt and eventually break the city Urban acupuncture is the weed and the acupuncture point is the crack The possibility of the impact is to-tal connecting human nature as part of nature

Casagrande utilized the tenets of acupuncture treat the points of blockage and let relief ripple throughout the body More imme-diate and sensitive to community needs than traditional institutional forms of large scale urban renew-al interventions would not only re-spond to localized needs but do so with a knowledge of how city-wide systems operated and con-verged at that single node Re-lease pressure at strategic points release pressure for the whole city

The theory of urban acupuncture opens the door for uncontrolled creativity and freedom Each cit-izen is enabled to join the crea-tive participatory planning pro-cess feel free to use city space for any purpose and develop his environment according to his will This ldquonewrdquo post-industrialized city Casagrande dubs the 3rd Genera-tion City characterized by its sen-sitive citizens who feel the call-ing of a sustainable co-operation with the rest of the nature sensi-tive citizen who are aware of the destruction that the insensitive modem machine is causing to na-ture including human nature In a larger context a site of urban ac-upuncture can be viewed as com-municating to the city outside like a natural sign of life in a city pro-grammed to subsume it

Urban acupuncture focuses on local resources rather than capi-tal-intensive municipal programs and promotes the idea of citi-zens installing and caring for in-terventions These small chang-es proponents claim will boost community morale and cata-lyse revitalization Boiled down to a simple statement ldquourban ac-upuncturerdquo means focusing on small subtle bottom-up inter-

ventions that harness and direct community energy in positive ways to heal urban blight and im-prove the cityscape It is meant as an alternative to large top-down mega-interventions that typical-ly require heavy investments of municipal funds (which many cit-ies at the moment simply donrsquot have) and the navigation of yards of bureaucratic red tape The mi-cro-scale interventions targeted by ldquourban acupuncturerdquo appeal to both citizen-activists and cash-strapped communities

Jaime Lerner the former mayor of Curitiba suggests urban acu-puncture as the future solution for contemporary urban issues by focusing on very narrow pres-sure points in cities who can ini-tiate positive ripple effects for the greater society Urban acupunc-ture reclaims the ownership of land to the public and emphasizes the importance of community de-velopment through small interven-tions in design of cities It involves pinpointed interventions that can be accomplished quickly to re-lease energy and create a positive ripple effect

He described in 2007 ldquoI believe that some medicinal ldquomagicrdquo can and should be applied to cities as many are sick and some near-ly terminal As with the medicine needed in the interaction between doctor and patient in urban plan-ning it is also necessary to make the city react to poke an area in such a way that it is able to help heal improve and create positive chain reactions It is indispensa-ble in revitalizing interventions to make the organism work in a dif-ferent wayrdquo

Taiwanese architect and academ-ic Ti-Nan Chi is looking with micro urbanism at the vulnerable and in-significant side of contemporary cities around the world identified as micro-zones points for recov-ery in which micro-projects have been carefully proposed to involve the public on different levels aim-ing to resolve conflicts among property owners villagers and the general public

A loosely affiliated team of ar-chitects Wang Shu Marco Casagrande Hsieh Ying-chun and Roan Ching-yueh (sometimes called WEAK Architecture) are describing the unofficial Instant City or Instant Taipei as architec-ture that uses the Official City as a growing platform and energy source where to attach itself like a parasite and from where to leach the electricity and waterhellip [The In-stant Cityrsquos] illegal urban farms or night markets is so widespread and deep rooted in the Taiwan-ese culture and cityscape that we could almost speak of another city on top of the ldquoofficialrdquo Taipei a par-allel city ndash or a para-city WEAK is calling urban acupuncture de-pending on the context as Ille-gal Architecture Orchid Architec-

ture the Peoplersquos Architecture or Weak Architecture The theory of urban acupuncture suggests that scores of small-scale less costly and localized projects is what cit-ies need in order to recover and re-new themselves

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

ldquoCommunity forestry is successful here with over 18000 community forestry user groups managing about 17 million ha of forest We have proven our-selves in forest protection

but there is a need to enhance our rural livelihood op-portunities through sustainable forest management Developing a PEFC-endorsed national forest certifica-tion scheme will help us to build recognition through-out the country on the potential for managing forests sustainablyrdquo

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

ParacityText Katie Cramer Fish Marco Casagrande

A paracity is an organic structure which can encom-pass a large number of human individuals It has some things in common with our current urbanised areas however a paracity is not bound to space It can live off a currently existing city and inhabit the same space It can be seen as a second layer on top of a society A paracity lives off another city like a parasite off its host

How will a paracity affect the city it is leaching from If you imagine an actual leech and how it sticks onto your leg and sucks from your body Not only does it take away a re-source from your body it can also pump actual parasites back into it which will harm your body However if you im-agine it as a structure leeching onto the main city it will pull resources from the city but also provide to the city and will grow through these actions Local knowledge can spread through the fabric and infil-trates the city The resources it takes from the city will how-ever depend more on what the city is able to provide rather than what the paracity wish-es to take from it This will then develop into an organic rela-tionship providing a physical structure where a community may begin to form The parac-ity would ideally be where old is combined perfectly with the new without having to be old but simply by acknowledging the old The paracity can do this as it attaches onto it and takes from the city what is no longer desired

The structure of a paracity is unique in its construction method but also in the way that it chooses to move away from conventional tradition-al planning and architecture It offers a personalized archi-tectural identity in which indi-

viduals may develop their own space and transform a struc-ture into a place The parac-ity as a space is interesting similar to nature which grows around what is built a paraci-ty will grow according to what is already present and what can be found to add onto that Where nature may strug-gle a paracity will find innova-tive solutions to incorporate something into the structure or simply build around or on top of it It is this biourban ap-proach to design which al-lows for the development of a unique structure in which indi-viduals will form a communi-ty These individuals will nat-urally come together as they have the will to create some-thing which is their own which they can appropriate and share with others In a growing soci-ety one must also consider ac-cess provision and capacity How will the design of a space cope with something which is completely unpredictable The answer is found in how nature copes with growth and change in provision The paracity has no limits which are not defined by nature itself The paracity offers a place with new aims and thoughts With a new sys-tem of thought we can forge a new place which creates the space for a new society to combine with what already ex-ists and the organic growth of nature

The structure must offer or-ganic growth and thereby give access to as much as it can The structure may fold itself around what is currently pres-ent and thereby incorporate it in its design How will individ-uals travel through this struc-ture once it has become more than just a structure The paracity seeks to be a point of play between the individual and the structure As Foucault has said as humans we need this play to help us enhance who we are and what we deliv-er This play will feed the struc-ture as well as relationships between the individual and the structure and others living in the city This play will form at the moment where the individ-ual becomes a part of a great-

er picture when an individual has invested in the city is the point where they will form a re-lationship which is constantly changing in order to accom-modate others as well as the change in nature

A crucial aspect for the suc-cess of a paracitic society in my view depends on how quickly a society will form and the pace at which it will grow Societies and relationships form organically over time and are dependent on the detailed design of the structure If one would put a very large num-ber of strangers together the chance of success at form-ing a society will be lower than when a group naturally forms to subsequently slowly ex-pands This will be dependent on the initial structure present but also on what comes readily available from the city If there is too much available for the paracity to leech on then there will be more chance for a fast growing structure which will not accommodate the natural growth we are seeking

A place will also depend on growing organically in order to function as a society Plac-es have rules and communi-ty engagement Elders often play an important role in being in charge and enabling a com-munity to grow around them according to unwritten rules like in Treasure hill In a parac-ity it is necessary for this hier-archy to form itself in order for the rest of the society to trea-cle down from this in such a way that there is no room for altruism and only co-depend-encies This allows a society to grow organically mimicking natural growth Where in na-ture a tree will not grow under another tree or too near anoth-er tree because they would be fighting for each others light ground and water in society we must live according to similar innate rules whereby we prove selfless and show an interest in the well-being of others A paracity must therefore grow according to need rather than desire When the city needs new labour or when relation-ships become complicated we

must envisage that new peo-ple will come and help to form a greater community

A community network of-ten refers to an online form of community whereby individ-uals become linked through interest and other personal-ity traits rather than accord-ing to location This changes the way our day to day society works If you think of a city no matter the scale we often do not interact with those in our close proximity If we are lucky enough to live in an area where people spend a lot of time we may get to know some famil-iar faces however we still wonrsquot often reach out for help or of-fer help as easily as we would if we were a part of a defined community network or living in a small village where every-one knows each other As indi-viduals we have the innate trait to want to help others whether it be because we care or sim-ply because it makes us feel good This gets lost in an in-dividualistic city where we find it more difficult to extend help to a stranger but also where there is often no one to rec-ognise and praise your efforts The paracity offers a solu-tion for this which is rooted in its design The paracity offers a communication which lies beyond the current systems whereby the city itself be-comes a form of communica-tion Those living in the parac-ity will communicate through the design and what they can offer to it

The paracity defines itself in its origin as reliant on another liv-ing structure in order to forge its existence Without another living structure it is unable to survive It leaches off society in order to make its own Through this act of leeching off another society it becomes to a certain extent dependent on it This dependency is what creates a community network in the par-actiy as individuals become reliant on one another to de-velop this complex structure The structure of this paracity will depend on what is readi-ly available and how different users come together and as-

semble these unique pieces It is this act of coming togeth-er which will help different us-ers to become more assimilat-ed with one another and begin to develop a network This net-work will then create a com-munity with co-dependencies In such a society where we are dependent on others it is more natural for individuals to form a society where they come in aid to one another The soci-ety will then evolve naturally according to this pattern and what nature makes available to them It is expected that the actual structure of the parac-ity will play a significant role in how the community inter-acts and creates links between one another Dependent on the structure and how easy it is to create links between different sections will depend on how easy it becomes to forge rela-tionships across different sec-tions of the design

Living in a close environment it becomes necessary to hold contact with one another as we are so dependent on what another individual chooses to do How someone else choos-es to expand or build their structure will directly affect those surrounding that struc-ture Whether it be through sound changing of available daylight or access All these things will come into play with the changing structure of the paracity A strong communi-ty network will help individu-als to form a social structure in which they aid one another to create a friendly more organic place to live It is this friendly more organic structure which will then allows the communi-ty to continue to live according to parasitic rules and not to re-vert to the destructive ways of a traditional society

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

Rigid fabricText Menno Cramer Picture Joni Virkki

The empowerment of novelty flexibility and change will cre-ate an environment in which humans can grow and live in a natural manner They will not be constrained by the current rigid fabric of urbanised areas that doesnrsquot allow for natural growth to occur

Many of the issues urban soci-eties are facing are caused by the lack of provision of life af-forded by current cities The rig-id urban fabric of urbanized ar-eas does not allow for natural evolution to occur Natural evo-lution within and amongst hu-man beings is crucial for a truly sustainable society The rede-sign and re-evaluation of urban areas can alter and improve the provision however this will only be a temporary solution as for a new rigid fabric a new static state is induced It is not natu-ral for humans to be in such a rigid dead fabric We are forced to move around in order to fulfil our basic needs Natural evolu-tion only occurs in places where the speed of urban sprawl ex-ceeds the planners or govern-ments influence on where soci-ety starts to fall apart and from within the ruins life can spread

Negative aspects of the current city structure are caused par-tially by the inflexibility of urban areas whereas a river moves over time cities are snapshots of pathways frozen in time Whereas tribal structures were in place to increase the social well being of a group the current urban metropolis seems to have lost this function User experi-ence design and human cen-tred design flourish more than ever However where are these views amongst the planners and architects Humans are and should be the center point of any architectural design So what does the concrete giant do for me What does it bring me

Studies have shown that city life is positively correlated with in-creases in depression burnout health problems obesity eco-nomic disproportions racism and a steep increase in nega-tive social interaction The cur-rent urban fabric has managed to evolve into a framework for a relatively sustainable capital-istic individualism where hu-mans mutually agree to ignore each other and avoid any major human interaction

However society as a whole is suffering from this Urbaniza-tion allows for the cohabitation of multiple social classes and groups however it does not en-courage natural social and indi-vidual well-being

Survival of the fittest has been eliminated in the physical terms however the battle for men-tal and physical space is even more ruthless Causing social discomfort and eg increased stress which is a dangerous threat to life in current socie-ty We all strive for superiority over other human beings Let it be economic physical phys-iological or mental We have constructed an urban fantasy of social cohabitation without ever intending to acknowledge the society one is a part of The discrepancy between personal well-being and social admira-tion is larger than ever

Humans are biological they come from nature and they are nature Humans need a space to live in because they canrsquot exist without being The current place present in a space where most of the earthrsquos human population inhabites is what we call urban areas An urban environment does not have the same quali-ties as a natural environment Todayrsquos society and social class has evolved from the neander-thalers and therefore we do not feel like caveman and wom-en anymore However everyone has neglected the fact that the current exposure to a non-natu-ral environment will harm us as human beings We have noticed negative consequences as list-ed above however thus far they have not outweighed the ben-efits Seeing as that urban ar-

eas are growing more rapid-ly than ever I believe we need to re-evaluate the urban fabric as such and propose a biolog-ical solution for urban growth

It is this biological solution which will host a new way of life which will address some of the issues presented above in a natural biourban man-

ner It is the way the issues are addressed through a this non-rigid structure which will aid society to develop and look at a new way of life The social interactions which are forged are there purely to empha-size the individual We work hard and network to grow per-sonally in a paracity this is the city and we can grow from it

around it with it and within it

Modernismi naumlkee kaupun-gin koneena ndash biourbanis-mille kaupunki on organismi Modernistisessa kaupunki-suunnittelussa joka on ollut vallitseva suunnittelupara-digma viimeiset 70-80 vuotta on vakavia puutteita joihin biourbaani kaupunkisuunnit-telu vastaa Paracity tarjoaa biourbaaneja suunnittelurat-kaisuja kaumlytaumlnnoumlssauml

Biourbaani kaupunki (kuten Paracity) tarjoaa rungon johon kaupunki voi kasvaa Paracity on kaupungin luuranko joka antaa tuen elaumlmaumllle Se ei nojaa arkkitehtien ja kaupunkisuun-nittelijoiden taitoon ennakoida tulevaa Sen sijaan Paracityn pohjana on paikallinen traditio Taipeissa elaumlauml edelleen vah-va perinne rakentaa ja viljellauml urbaanin kaupungin jakojaumlaumln-noumlsalueita Taipeissa kaikkiin

COMMEDIA

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

COMMEDIA

DELLrsquoARCHITETTURA

Text Marco Casagrande Picture Niilo Tenkanen

Architecture gives the com-mands and architects listen Actually nature gives the com-mands and architecture takes form Architect is a design shaman that communicates with this reality Design cannot replace reality nature Human control must be opened up in order to let nature step in Ar-chitecture must be ruined Ruin is when man-made has be-come part of nature

To be present is the key of all art Architect is a site-specif-ic instrument through whom the great voice of architecture starts to resonate and find form This great voice is weak and needs great presence sacrifice and sensitivity to be heard Architect is one of the sensitive beings to hear this voice and protect the sound Architecture either is or it isnrsquot It cannot be speculated Archi-tecture is a real reality

ldquoWhat really happened to Porcupinerdquo

ldquoOne day he came back from the Zone and be-came amazingly rich amazingly rich The next

week he hanged him-selfrdquo ndash Stalker Tark-ovsky

People live in space and this connection can be art a higher thing than what could be de-signed Architecture is an ac-cident which is a higher thing than human control In order to understand the accident and to let life run through it one must be present To be present is the key of all art This crack in human control is the acupunc-ture point through which the organism of architecture can grow Biourbanism is the city of cracks Architecture is a medi-ator between man and nature connecting human nature with the rest of nature reality Archi-tecture is the art of reality

ldquoLet everything that has been planned come truerdquoLet everything thatrsquos been planned come true Let them believe And let them have a laugh at their passions Because what they call passion actually is not some emotional energy but just the friction between their souls and the outside world And most important let them believe in themselves

Let them be helpless like children because weakness is a great thing and strength is nothing

When a man is just born he is weak and flexible When he dies he is hard and insensitive When a tree is growing itrsquos tender and pliant But when itrsquos dry and hard it dies

Hardness and strength are deathrsquos companions Pliancy and weakness are expressions of the freshness of being Because what has hardened will never win

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

Ghan Shyam Pandey Green Foundation Nepal

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Local Nordic rootsCLTrsquos origins reach back to the early 1990rsquos when it was first pro-duced in Austria As the home of early CLT development Austria still produces most of the worldrsquos CLT today with countries such as Germany and Switzerland occu-pying a fair share of the market CrossLam responds to a void in the market for Northern Europe-an CLT The quality of timber in the Nordic countries is renowned world-wide ndash Finnish wood is famed for its strength endurance and aesthetics and compares favorably with most other timber produce

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

Energy efficiency and ecological footprintsThe potential of CLT in creating energy-efficient buildings is excel-lent CLT panels trump concrete and steel structures in terms of their thermal properties CLT pan-els have extremely low thermal conductivity and the softwoods used for CLT production generally have high heat storage capacities Finished CLT panels are therefore naturally sensitive to seasonal variations in climatic conditions responding to their exteriors and creating pleasant microclimates in interior spaces for the occupants

Manufacturing CLT not only pro-duces less GHG emissions than the creation of steel or concrete el-ements but catches green house gases into the products them-selves making CLT a leading op-tion for the creation of carbon zero architecture Because CLT panels are made to custom dimensions and patterns for each client the production process produces little waste

Timber high-rise ndash responding to urbaniza-tion and housing needsFrom the onset of the Modern Movement pre-fabrication and elemental construction have not only been considered revolution-

ary developments in building con-struction but also powerful agents of social change

Although the adverse effects of in-famous rapidly-constructed con-crete towers loom in recent mem-ory CLT rises to the challenge of using pre-fabrication and ele-mental construction to more hu-mane ends We have taken many lessons from the rapid spread of modularized and pre-fabricated architecture in the 20th century but by virtue of timberrsquos manifold qualities as a building material have avoided the pitfalls associat-ed with countless concrete or steel buildings erected as panelized systems CLT challenges the per-ception that creating spaces with the warmth of home is mutually exclusive with rapid construction its manufacturing and construc-tion processes recall the easiness of concrete elements but its aes-thetic material and acoustic qual-ities mirror more more comforting values that help create comforta-ble spaces for occupants

Emergency housing amp catastrophe-proof architectureThanks to its uncontestedly quick erection time CLT panels are an excellent choice for areas affected by natural disasters where quick construction is the prime concern in addressing large-scale loss of housing

Thanks to its structural qualities new builds erected to replace destroyed housing need not re-main temporary CLT can be used to construct catastrophe-proof buildings that resist seismic im-pacts and provide for long-term shelter from natural disasters in a range of climatic conditions CLT has been proven to resist seismic effects better than most other ma-terial options

CrossLam ndash paving the way to the futureThanks to our strong local roots we have the audacity to reach out to a global scale to tackle todayrsquos most serious challenges in archi-tecture and construction Cross-Lam is proud to collaborate in the PARACITY initiative a bold con-temporary scheme that has the potential to revolutionize urban and architectural development in todayrsquos world Innovative thinking flourishes when it is supported by powerful technologies and as partners of a project as daring as PARACITY we are excited to follow CLTrsquos role in transforming the cit-ies and buildings of tomorrow

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality

CrossLam manufactures each CLT panel exclusively according to the clientrsquos needs The panels can be used to construct walls floors and ceilings for a range of archi-tectural projects CLT is a struc-turally stable and environmentally conscious material that combines the ease of prefabricated con-struction with the inherent beauty and atmospheric qualities of tradi-tional timber building

Rapid production and constructionBy virtue of its rapid manufactur-ing process and simple raw-ma-terial-to-end-product sequence there is no need to allow for sev-eral weeks of production and transportation time as drawings for desired CLT panels can be sub-mitted to CrossLam as little as a week before intended production in most cases Since changes can be made to the size and cut of the CLT panels up to a week before production there is more room for end-of-design changes to take place and the risk of outdated in-formation leading to mismatched end products is minimized

The speed of construction also significantly reduces the risk of moisture-associated problems which have plagued schools and hospitals built out of reinforced steel and concrete in the past dec-ades Although special care must be taken to keep CLT elements dry on the construction site the sim-plicity and speed of the erection process ensures moisture-free end results leading to healthier and stabler buildings Due to its high degree of pre-fabrication CLT is produced in highly controlled interior environments reducing the window in which climatic fac-tors can impact the product in the construction chain The effortless construction sequence of CLT also means the demand for highly skilled labour in the erection pro-cess is lower than in many other types of construction since the

panels are set together in a clear assembly-ready fashion with min-imal jointing and other work re-quired on site

Although the production costs of CLT are of the same class as for concrete or steel the rapidity of the construction process makes it compare favorably to other mate-rials It is by far the quickest mate-rial to erect on site drastically cut-ting the time needed to complete the construction phase of a given project

Customization and craft-ednessWith CLT the simplicity of the manufacturing procedure shifts the focus from standardisation to liberation as no elements are pro-duced en masse to sit in storage literally each piece is produced ac-cording to its own unique require-ments leading to a perfect line from demand to supply rather than the other way around Demand as defined by designers and contrac-tors themselves sets the bound-aries for subsequent supply CLT panels maximize the degree of control undertaken by the design-er in essence the simplification of process leads to the maximization of design opportunity

The designer becomes as much as maker as a draftsman respon-sible for the production of every single element in the CLT building design The designer can examine each panelindividually in the man-ufacturing process ensuring the final look of the panels matches stringent expectations

Paradigm shift in constructionWe believe that in producing CLT we are in fact weaving together not only timber boards but strands of the future We sit at the vertex of a paradigmatic shift in the way timber is understood in architec-ture today wood is a solid build-ing material not merely a skele-tal frame structure or decorative element CLT nullifies the need to distinguish between a structur-al frame and building technology components that infill the struc-tural backbone for it satisfies a range demands at once making detailing both easier and more re-liable

Superior technical quali-ties and engineering per-formanceThe most ingenious ideas are often the simplest By gluing to-gether layers of timber with alter-nating grain directions the natural advantages of timber as a build-ing material are magnified and strengthened even further

CLT transforms timber into a high-ly fire retardant solid end product Unlike thin timber elements that catch alight in traditional skele-

tal or balloon frame construction systems the mass and density of CLT panels allows for the fire to char the surface layers at slow speed thus significantly deceler-ating the process of burning Addi-tional coatings on the layers ofCLT panels can provide more rigorous fire resistance Thanks to its tight-pressed solidity CLT is not subject to shrinkage or swelling during its lifecycle which makes it a high-ly reliable material of choice The moisture problems that plague concrete and steel buildings of the 20th century are not a risk factor in CLT buildings due to the high de-gree of pre-fabrication that takes place in highly controlled interior environments

The home-like warmth of timber interiors can now be achieved by using the time previously neces-sarily dedicated to design frame column and slab systems to focus on the most intimate details of the finish Simplifying the construc-tion flow to a part-by-part erection process in CLT construction allows more time effort and concern to be dedicated to the final finish of the spaces being designed Donrsquot let the ldquohouse-of-cardsrdquo analogy fool you the construction process is indeed simplified to setting pieces together as easily as a house of cards but the end result is a sturdy and steady building with as much strength and force resistance as any concrete- or steel-construct-ed equivalent

ldquoWe need a recognized certification system that in-corporates our specificities and realities promotes the value of our forest products and ensures an equal share of benefits along the value chain Our stakehold-ers are motivated by the bottom-up approach keen to participate in the creation of their own certification system and wanting to ensure they understand their system once it is readyrdquo

Christine Nkene PAFC Cameroon

ldquoPrivate forest owners in Hungary view PEFC certifi-cation as their only affordable option and everyone including those already involved with other systems value PEFC for respecting our natural economic and social environment Legislative developments like the European Union Timber Regulation have also drawn the stakeholdersrsquo attention towards certificationrdquo

Endre Schiberna Hungarian Forest Certification Non-profit Ltd

ldquoCommunity forestry is successful here with over 18000 community forestry user groups managing about 17 million ha of forest We have proven our-selves in forest protection

but there is a need to enhance our rural livelihood op-portunities through sustainable forest management Developing a PEFC-endorsed national forest certifica-tion scheme will help us to build recognition through-out the country on the potential for managing forests sustainablyrdquo

Ghan Shyam Pandey Green Foundation Nepal

PEFC (Programme for the Endorsement of Forest Certifica-tion schemes) is an international forest certification system promoting ecologically socially and economically sustainable forestry throughout the world Approximately ten percent of the worldrsquos forests are certified and of these two thirds - about 250 million hectares - to PEFC standards PEFC certified forests are found in tens of different countries

To meet PEFC certification requirements forest management must satisfy certain standards with regard to biodiversity for-est health and maintenance as well as recreational use In ad-dition there are requirements for following the passage of

raw materials and wood-based products throughout the whole supply chain These guarantee that raw materials are from cer-tified forests

Approval for certification requires audit by an independent and qualified certifier to ensure that forest management wood raw material sources and follow-up meet PEFC standards

PEFC certified products their packaging and documentation can be recognized through the PEFC logo A company can ob-tain a PEFC logo license when the companyrsquos activities have been certified

Introducing CrossLam Finlandrsquos first CLT manufacturer

Text Sofia Singler

CrossLam is the first Finnish man-ufacturer to produce CLT panels out of local raw material with lo-cal know-how We stand firmly on our Finnish roots in order to reach out to solve global problems and are immensely excited to collabo-rate in the PARACITY initiative and shape the future of architecture As the first Finnish CLT producer we are proud to be part of a para-digm shift that challenges the sta-tus quo of the construction indus-try today and rise to face the most weighty challenges of our time We believe in responsibility inno-vativeness and open-mindedness as our core values

What is cross-laminated timberCross-laminated timber or CLT is a massive timber element consist-ing of layers of timber planks glued and pressed together at right an-gles This process of cross-lam-ination is what ensures the sta-bility and strength of CLT panels CLT takes timber construction to a new level timber is now not only a skeletal frame material or decora-tive component but a solid build-ing material that can be used for purposes as variable as concrete or steel A single CLT panel can satisfy multiple demands at once combining structural strength and stability with aesthetic beauty CLT is a massive material that nullifies the need to distinguish between a structural frame and building technology components that infill the structural backbone ndash it can be left exposed in interior spaces meaning it can bear the load of the building as well as function as an aesthetic wall inside

Manufacturing process outlineCLT panels are composed of an odd number of layers ranging from three to eleven usually resulting in a final thickness of around 30 cm The maximum dimensions of a finished panel can reach around 3 x 12 m

Timber planks are set on top of each other at right angles to cre-ate a large wood mat which is then glued and pressed together After moving through the glueing station the mat is pressed to-gether in a single session to form a complete solid CLT panel The glue used in the manufacturing process is formaldehyde-free and environmentally friendly Once pressing is complete the panel can be cut into the necessary di-mensions specified by the client and the product is ready to go

CLT agrave la KuhmoWe craft our CLT panels entirely in Finland which allows for shorter and more flexible delivery times than competitors leading to lower

overall costs The Northern Finn-ish Scots pine and spruce we use for our panels is especially suita-ble to be left exposed indoors due to its high aesthetic quality
