INTRODUCTION TO THE SITEpage 4

A city in transformation

As part of Southbank, the Borough area is undergoing a massive process of transformation, that will in the close future completely redefine its character. The present study is testing different development options, aiming to provide fruitful indication for the time to come.

PLANNING FOR THE COMMUNITYpage 5

Common issues, community solutions

Any radical urban transformation risks to compromise the life of the commu-nity of residents. The main challenge of the redevelopment is to respond to the strong demand of new housing in the area, without compromising the provision of green areas and public open space.

EXPLOITABLE AREApage 6

Where to intervene?

Matters of fragmented land owner-ship and pre-existing restriction often compromise the viability of radical de-velopment schemes. For this reason in this study it was chosen to intervene only on the sites that have been iden-tified as more likely to be changing in the next future.

RESTRICTIONS

DEMOLITION

Most of the buildings demolished will be redeveloped in place maintaining the same function. As for the former Brandon House, in this scheme it has been adopted the redevelopment by Allies and Morrison, whose planning consensus has already been given by the local authority.

DEFINING THE SITEpage 7

One area, different sites.

Due to the current complexity and fragmentation of the area, it was cho-sen to divide what has been identified as exploitable area into three different sites. As for the main one, the evalua-tion will consider both the entire site and the net area of intervention.

site 30.24 HA

site 15.2 HA

The proposed scheme allows the re-developement of the three sites as dif-ferent operetions in terms of time and management. Nevertheless, this brief suggests design elements and prin-ciples in order to achieve a cohesive transformation for the entire area.

DESIGN PRINCIPLESpage 8

Development guidelines

The transformation of the area is led by few simple principles making the new development cohesive with the pattern of buildings and spaces of the exsisting urban fabric, and refer ing at the same time to forms and typologies occurring in similar contemporary de-velopment in London

Considering options

The area currently presents buildings and spaces that vary dramatically from the two stories Red Cross cottages to the planned eight stories redevelop-ment of Brandon House. At the same time, it belongs to a broader area in London where skyscrapers coexist with suburban-like elements.

MASSING AND SCALE

View of the study model

The different options presented in this study take in consideration the diverse context of the area, proposing on a similar spatial layout three different approaches in terms of the scale and the impact of the new development.

Page 10: Southwark Development Appraisal

MASSING AND SCALE: OPTION 1page 10

Climbing over the top

The current guidance from the local planning authority suggests that the ideal height for any new development should be between six and eight sto-ries, reflecting the current state of the area. At the same time several high rise buildings appeared recently in the surroundings of the sites.

View of the study digital model

This created a precedent in the area for development over the guidance standards, changing the local charac-ter and expanding the range of height difference between buildings. The first option takes this into account, testing the impact of medium rise elements up to fifteen stories height.

Page 11: Southwark Development Appraisal

MASSING AND SCALE: OPTION 2page 11

Six to seven storeys

The second option presented sets a limit of six stories for the new develop-ment, allowing an extra level for roof top houses. The general height varies according to the context, down to two to four stories for new building adja-cent to listed buildings such as the Red Cross cottages.

Page 12: Southwark Development Appraisal

MASSING AND SCALE: OPTION 3page 12

Refurbishment vs demolition

In the third presented option the two existing housing estates on the site (formerly social housing) are retained and refurbished. While mitigating the visual an social impact of the new de-velopment, this option drastically re-define the amount of total units that the scheme can deliver.

PARAMETERS: PUBLIC SPACEpage 13

Publicly accessible open space

Developing an area with a high pro-portion of unbuilt space is always per-ceived as a loss from the residents.It is therefore of extreme importance to distinguish generic unbuilt space from the open space that is publicly accessible and presents a high envi-ronmental quality.

Pubblicly accessible open space currently on site

The new scheme takes this into max-imum consideration, not only main-taining and increasing the area dedi-cated to gardens and urban squares, but also improving the streetscape by introducing shared surfaces and enlarged pavements, reclaiming the streets as public space.

Space for everyone

Parallel to the increasing of public open space, the current scheme rede-fines the amount and the quality for the provision of shared private space. This constitutes not only a strate-gic environmental component of the scheme, but also a significant visual amenity for the residents.

At the same time, it provides an amount of doorstep open space that can potentially be turned into play-ground for up to 270 new children in the area. The access to these spaces, limited to the residents of the singu-lar blocks, guarantees safety and con-trolled maintainance costs.

PARAMETERS: PERMEABILITYpage 15

A breathing city

Permeable surfaces are a key factor in preventing the overloading of the city drainage system in case of heavy rain. At the same time, they contribute in collecting and filtering pollutant ele-ments from the air, they mitigate the heath-island effects and provide habi-tat for urban wildlife.

Green roofs have been adopted on most of the scheme in order to com-pensate the limited provision of per-meable surface at ground level, due to the buildings footprint and matters of maintainance and cost for the paving of the circulation areas.

SPATIAL LAYOUTpage 16

Different blocks, different scale

The definition of the form and scale of the proposed new blocks takes in con-sideration the fragmented and diverse carachter of the area. Where possible, big scale blocks where introduced, in order to allow the introduction of dif-ferent functions and flexibility in the range of units.

Completing the scheme is a series of small scale infill interventions, filling the gaps in between existing and new buildings, contributing not only to achieve higher density standards, but also to redefine the spatial layout of the area.

More open space, more light

The increased public and private open space, and the general orientation of the buildings, guarantees an optimal provision of direct sun light to the area. The impact of the medium-rise buildings is limited by their location and position setting back from the main street front.

Active streets, active city

In the general outline for the development of the area, a great attention has been given to deliver a constantly active ground floor, embracing the gardens and the other public spaces with active building fronts, limiting back service areas and avoiding blind spaces.

A place called home

The provision of residential space is an answer to the current high demand for homes in the area, and a legacy to the carachter of the area. Nevertheless, new office and hotel space has been inserted in proximity to the most ac-tive sides of the site, such as Borough High Street and London Bridge.

Over the top

Rather than just being a roof, the use of the top of most of the buildings have been optimised by introducing extra concentrated residential space and rows of penthouse, at the same time an ironic tribute to a typical typology of the area and a response to a local high demand for luxury units.

SECTION 1

The scale of the new intervention reduces

drastically in proximity of listed buildings,

such as the Red Cross cottages.

The school is enclosed by double storey

maisonettes, allowing a continuously active

front on the perimetral street.

Inserted at the core of the central mixed

use block, the new school and the residential

upper floors share the same courtyard at

different levels.

Small scale infill interventions mediate

the relationship between the new

development and the existing context.

Another role of the infill intervention is

to complete existing blocks, redefining

their fronts.

Roof top penthouses contribute to define

the character of the area. The North-

South orientation of the streets provides

sufficient sun light even in the narrower

sections.

By covering the main parking areas inside

FUTURE ARMATUREpage 29

Visions for the future

The proposed development scheme is a fundamental step supporting the transformation of the entire Borough area. It will promote the regeneration of the High Street by consolidating the inner part of the block, providing more living space and new commercial space in strategic locations.

Future armature for the area

At the same time, it will enrich the lo-cal environment through the redesign of the existing open spaces, the crea-tion of new ones, and the promotion of Union Street as part of a network of quality leisure urban spaces for res-idents and visitors.

note 2

The abitable rooms ratio was used to calculate the amount of abitable rooms for the retained residential area.

note 1

The total amount of new units is listed separately in this database, that is used in the main spreadsheet to generate automatically the number of afforda-ble and for sale units, according to the rate of the rate of affordable housing given as an input. This allows a quick-er and more flexible way to evaluate different options.

Playing with the numbers

Having linked all the calculations to the rate of affordable housing allowed an easy comparison of the different options. In particular, it is interesting to note the different amount of af-fordable housing allowed by the three schemes, having as a result the same value per hectare for the area.
