background Between 1951 to 1961 the increasing

population of Mumbai rapidly outgrew its capacity for infrastructural development and projections for next decade indicated a much higher pressure on city unless it was properly addressed .The idea of satellite town –Navi Mumbai was bred to effectively decongest the population growth and the city and industrial development cooperation of maharastra pvt ltd. Conceived as its principal city planning organization to adequately support the shift

The CIDCO Housing(1988-93) in Belapur Central Business district was planned as a scheme that would provide extremely low cost accommodation for the lowest income groups.

The programme requirement of 1048 apartments was varied mostly comprising of one to two room units and some larger two bedroom units that could be sold individually.

Allowing an overall density of 55 units per acre ,the unit sizes range from 18 to 105 square meters with nearly 77 percent having an area of 42 sqm or less.

The smaller units of 20 to 35 square meters are grouped within a precinct defined by two surrounding roads giving access to inner pedestrian pathways and courtyards

• Raj Rewal, on his housing solutions: “The prototype is regard as the cluster system, and not the project itself. We incorporated more than 16 types of individual flats and house designs within the scheme, but the system we designed to create public space, semi-public space and private space - important features in our climate and in our culture. is what is prototypical. These different spaces correspond to different relationships among people. One category of acquaintance is greeted on the street, but not taken into the privacy of the home. Another category belongs to the mohalla, and with them, one has a closer relationship. Each category of relationship has its corresponding category of social space. Whenever one designs mass housing one has to have some sort of prototype like this in mind .Otherwise, one will again end up with the block and slab invented by the West and repeated throughout the world, or terrace housing

BUILDING TYPOLOGY

Building materials

Materials

Rough cast plaster punctuated with bands of cheap handmade tiles was chosen as the building finish keeping in the mind the meagre budget and the brunt of Mumbai monsoons.

Lower portions of the building along with flanking walls use quartzite stone and a honeycomb lattice distinguishes parapet walls

CLUSTER

Use of cross wall and grouping of toilets has resulted in cost reduction Have attached terraces at upper floor. The units are arranged in such a way that it creates a network of courtyards and roof

terraces fostering community interaction. Courtyards turn individual blocks into chains, modules are set very close together,

blocks with courtyards are grouped as quarters The Project was designed as a high density settlement to overcome the challenges of

the limited land but also to create a high quality urban space derived from a largely naturally developed traditional village (which usually consists of squares, courtyards, terraces and balconies).

When planning the chain of ‘molecules’ , great emphasis was laid on the connections implied by communally used spaces. Open staircases

Reduce covered area of circulation to minimum Inconvenient during rainy season

Parking space Since it was build for lowest income group the architect assumed that the necessity

of parking space would be bare minimum

Pedestrian circulation Width of pedestrian pathway = 3m The creation of the traditional narrow street , linking all housing units, provides

intimate encounters between people and a sense of belonging to the neighbourhood square.

Vehicular circulation The internal spaces are free from vehicular traffic Width of vehicular road =6m

Courtyards

The interlocking courtyards accommodate different functions and create a micro climate within the site.

Children's play areas

Children's play area was not provided.

The open staircase linking the 1st flr

connecting 2 units reduces the cost of circulation area.

The pattern of this cluster is based on joining L type units in several ways on a steep sloping part of a hillock.

The method of joining blocks is based on the contours of the site. At the entry points, the edges of joined together to define TYPE 1

- The area on which the blocks were built had a lot of levels.Some on the houses were built above the road level some were built below it.

- Except for block F proper parking spaces were not provided for the rest.

- The window sizes are very small (0.5m*1.2m).

- The buildings which were not in use are not properly maintainedSome of the pathway provided in the residential areas are in very poor condition.

- The spaces around the residential blocks which are not used were converted into a waste disposal area.

-The changes in the buildings over time.

-Verandahs and terraces converted in to rooms.

-Due to no department store provided so a room was converted into a store.Balconies were built randomly.

POSITIVE POINTS NEGATIVE POINTS• PRESENCE OF OPEN

COURTYARDS, PARKING SPACES GIVING A FEELING OF OPENESS. THESE SPACES ALSO HELPS A GREAT DEAL IN THE VENTILLATION.

• ABSENCE OF MARKETS AND HOSPITALS IS THE MAJOR CONCERNS OF THE RESIDENTS AS THEY HAVE TO TRAVEL ALL THE WAY TO NERUL FOR EMERGENCIES.

• TREES PLANTED ON BOTH SIDES OF THE STREETS CREATE A CANOPY FOR THE RESIDENTS TO WALK UNDER.

• LEAKAGE ISSUES DURING THE MONSOONS AND SECURITY ARE THE OTHER WOES OF THE RESIDENTS.

• OPENINGS SUCH AS DOORS AND BALCONIES WELL-PLANNED, SO AS TO PROVIDE GOOD LIGHTING AND VENTILLATION.

• THE DISTANCE BETWEEN 2 BUILDINGS AT SOME PLACES WAS BARELY 3 MTRS. WHICH RESTRICTED LIGHT AND VENTILATION.

• THE NEGETIVE SPACES CRESTED DUE TO THE ARRANGEMENT OF BUILDINGS WERE MADE GREEN SPACES .

• THE ELDERLY OR HANDICAPPED FACED PROBLEMS DUE TO THE NO. OF STEPS .

• RETAINING THE CONTOUR LAND,HELPED IN THE DRAINAGE AND ALSO AVOIDED WATER LOGGING PROBLEMS.

• THE GARAGE SPACE ALLOTED TO THE ROW HOUSES WERE CONVERTED TO STORE ROOMS DUE TO WHICH THE CARS HAD TO PARKED ON THE ROADS.

• THE PARSIK HILLS, BEHIND THE COLONY, CREATS A PICTURESQUE VIEW.
