1. RUOCHEN YANG Oct. ~ Nov. 2012 OF MUMBAI ANALYSIS
2. GEOGRAPHY -The city of Mumbai is situated on Indias west
coast, on the Arabian Sea, roughly 500 km south of the Tropic of
Cancer. Originally, the city rested upon seven small islands. These
islands are now connected to one another by reclaimed land.THE CITY
MUMBAI ECONOMY -Mumbai is Indias largest city (by population) and
is the financial and commercial capital of the country as it
generates 6.16% of the total GDP.

4. THE CLIMATE The Climate of Mumbai is a tropical wet and dry
climate. Mumbais climate can be best described as moderate
temperatures with high level of humidity. Its average temperature
is 27.2 C and averageTHE CITY MUMBAI precipitation of 242.2cm. The
temperatures in average about 30 C in summer and 18 C in winter.
Between June and September, the south west monsoon rains lash the
city.
5. CAUSE OF FORMATION -The growth of immigration: according to
the official survey in 2001, the population of Mumbai reached
12million. The rapid population growth is one of the main reasons
of Mumbais housing tension. -Severe gap between the rich and the
poor: the colonial malformed economic rule left, as well as uneven
economic development, resulting in the severe gap between the rich
and the poor. Table of The Poor Population in India 1960 1970 1980

those new planes could not be realized well.

16. EXISTING TYPES OF HOUSE 1. Chawls & Patra chawls:
-constructed in abundance in the early 1900s, now facing the
threaten of collapse. 1.1 Chawl They are often 4 to 5 stories with
about 10 to 20 tenements; A usual tenement in a chawl consists of
one all-PROPOSED POSITION purpose room, that functions both as a
living and sleeping space, and a kitchen that also serves as a
dining room; People living in a chawl have little privacy. Due to
the close nature of the quarters, trivial news and gossip travels
quickly. On the other hand, however, this intimate living situation
also leads to a friendly atmosphere, with support networks akin to
familial relationships. 1.2 Patra chawl Consists mainly of
semi-permanent structures both authorized and unauthorized.

settlements falling under the category of slum. Consist of various

18. 3. Pavement dwellings: Pavement dwellings are shanties
built on footpath alongside the road, close to workplace. The
living conditions in pavementPROPOSED POSITION dwellings are worse
than those in squatters. Most of the pavement dwellers pay rents to
local strongmen who informally control the pavements.
19. OBJETIVES -Propose the restructuring and reorganization of
these places to improve their basic needs, referring to their
culture, environmental factors, climate, materials, structure and
infrastructure; -To find feasible house forms for slum
dwellers;PROPOSED POSITION -Definite habitable green spaces,
focusing on methods involving sustainable technologies; -Creating
multifunctional places to enrich the city life of the slum
dwellers.
20. GENERAL SITUATION Chawl buildings typically have two to
four stories with ten to twenty units on each floor. Each unit has
one or two rooms and opens in a common corridor. These units are
typically 15- 20m each. Each roomHOUSE FORM PROTOTYPE of 2.75m2.75m
are used as multifunctional areas. The toilets are outside the
units. The overall placement of the toilets differ from chawl to
chawl but typically, four to five toilets are located towards the
end of the chawl. There is one common bathing area or a common
washing area. Every unit also has one bathing area called mori.

21. -The overall layout of this chawl CHAWL FORM A is a C. At
one end of the C shaped chawl are the four common toilets on each
floor. -The internal courtyard inHOUSE FORM PROTOTYPE formed by the
C shape of the building was originally used by children to play.
Now it is mostly used by the residents to hang clothes, park cycles
and carry out other daily chores. Activities like cultural events
also happen in the courtyards. The internal courtyards form a very
significant parts of the chawl complexes from a social as well
CHAWL as spatial point-of-view.
22. CHAWL FORM B -This chawl is linear and has toilets on
either ends of the chawl. There are two toilets onHOUSE FORM
PROTOTYPE each end for eight units in all. -- -Although the shapes
of the chawls are slightly different, their overall layouts are
very similar in that they have common corridors that circle
internal courtyards and provide access to individual dwelling units
as well as shared toilets and staircases. CHAWL

25. MULTIFUNCTION The corridors or balconies at least 1.8m wide
are ideal but in fact the balconies or corridorsHOUSE FORM
PROTOTYPE of 0.9-1.2m wide are used the most. This is true in the
case of chawl corridors that are less than 1.8m wide, yet are one
of the most multi-functional areas in the buildings. It is used for
sitting, sleeping, reading, storing and playing. The families often
make a sitting cabinet with storage in it and keep it in the CHAWL
corridor.
26. MULTIFUNCTION Other multi-functional areas of the chawls
are the rooms of the unitsHOUSE FORM PROTOTYPE themselves. -The
living room is typically used for entertaining, sitting, studying ,
sleeping, watching TV, chatting and so on. -The kitchen is used for
cooking, dining, bathing, slee ping, sitting, changing and storing.

27. STRENGTHS -Social network The analysis shows that a dense
social-network between theHOUSE FORM PROTOTYPE residents is one of
the main reasons for them to live in the chawls. The building form
of the chawls contributes substantially to the close-knit social
life that the residents lead. The combination of all common areas
like courtyards, corridors, staircases and so on provide ample
scope for social interaction in these cohesive chawl communities.
This social network is the support system of the residents and
CHAWL needs to be maintained.
28. Research has shown that social The combination of spaces
like the networks often play an important corridors, courtyards,

where the social in life and that their connections are created. If

rent is not more than Rupees (Rs) 250. The rents ofHOUSE FORM
PROTOTYPE newer one bedroom 710 square feet apartments in the same
case study areas are anywhere from Rs. 25000 to Rs. 50000. In a
dense city like Mumbai, with a lack of affordable housing, chawls
provide a sustainable model for middle class housing that should be
maintained and can potentially serve as a model for future housing
projects. -Good location. Everyday amenities lie within walking
distance of chawls. CHAWL
30. WEAKNESS The residents do find using the common toilets
awkward and inconvenient, especially the women, but they have
become accustomed toHOUSE FORM PROTOTYPE this condition. Including
the toilets in the units of the existing structure would be
difficult because this would require significant structural and
utility changes. If these changes were possible, many chawls in
Mumbai would have already made them. This suggests that simply
adding a toilet in each unit is not possible unless it is
reconstructed or is a new chawl building. It is very inconvenient
for the person living on the other end of the C to pass all the
units CHAWL just to reach the other end to use the toilets.
31. WEAKNESSHOUSE FORM PROTOTYPE Many of the original timber
ceiling joists have been replaced with steel members. In some
places, steel W-sections are used as additional columns. These
structural additions were the result of strengthening work
conducted by an engineer ten to fifteen years ago when cracks were
seen in the original CHAWL timber columns and beams.

concerned that the old chawl sustainable living for the middle has

get pulled down one day.
33. SUPPORT Both DB Realty and Lokhandwala Builders are looking
forward for redevelopment of this huge slum of about 1.68 acres and
residents areHOUSE FORM PROTOTYPE tired of waiting since last 8
years now. Many have sold out their homes in less cost because of
need of money. In Worlis Jijamata Nagar, a hut costs Rs 45 lakh. DB
Realty and Lokhandwala Builders are eyeing this slum settlement
spread over 68,400 square metres. DB Realty has already spent Rs 16
crore on buying several shanties. "The land will be worth Rs 1 lakh
a square foot after redevelopment so they can afford to spend
crores," says Datta Navghane, chairman of the slum society. A
builder has already offered Rs 45 lakh per shanty in Worlis Mahatma
Phule Nagar. CHAWL
