Case Study of the Income Tax Colony, CBD Belapur

A.D. 4.2
Group 8

3. 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

4. • 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

The system of connecting the blocks is an important feature of the pattern.
The form of every block is different and it is patterned in different
formations based on the typology of the site, to create squares and
pathways.
A sense of enclosure and continuity of movement is maintained throughout
the scheme.
The division of site is accentuated by different types of building blocks
designed on the basis of dwelling unit areas.

B-25 sq. m
C-34 sq. m
D-40 sq. m
E-50 sq. m
F-70 sq. m
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

12. 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.

13. 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.

floor and a smaller unit

the 1st flr.
 Private roof terrace for
each unit.
 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

24. - 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
maintained
Some of the pathway
provided in the residential
- The spaces around the
residential blocks which are
not used were converted into a
waste disposal area.

25. -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.

26. 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

HOUSES WERE CONVERTED
TO STORE ROOMS DUE TO
WHICH THE CARS HAD TO
