PRE-DESIGN STAGE ANALYSIS<br />
Objectives:<br />
• To improve and upgrade the existing slum area<br />
• To provide serviced sites for new housing developments instead of<br />
building complete houses.<br />
• To provide for 6,500 residential plots ranging in size from 35m 2 for<br />
EWS to 475m 2 for high income groups<br />
Financial Aspects:<br />
• The idea was to mix some middle income plots with EWS plots to<br />
use the profits to raise capital towards development of local trades.<br />
• Funding – 100% public sources.<br />

OBJECTIVES<br />
The general objectives of Aranya were to:<br />
• Create a township with a sense of continuity and fundamental<br />
values of security in a good living environment.<br />
• Achieve a community character by establishing harmony between<br />
the built environment and the people.<br />
• Create a balanced community of various socio-economic groups to<br />
evolve a framework through design.
EVOLUTION OF MASTER PLAN<br />

N<br />
Initial stage of proposed plan<br />
with distributed open spaces and<br />
street hierarchy<br />
N<br />
Later stage of development to with<br />
rectified orientation to minimize heat<br />

THE NEIGHBOURHOOD CONCEPT<br />
Concept<br />
• Slum development project<br />
• Inspiration from existing slum<br />
settlements in Indore<br />
Characteristics<br />
• Mixed and multiple land use<br />
• Formation of small<br />
neighborhoods and houses<br />
extending to the outdoors.<br />
• Small shops operating within<br />
congested areas.<br />
• Trees planted in public places<br />
• Streets accommodating social,<br />
economic and domestic activities.
SITE ANALYSIS<br />
• Urban Indore city 214 sq. km.<br />
• Major development along Delhi –<br />
Mumbai highway running through the<br />
city in the north south direction<br />
• Surroundings: - Delhi-Mumbai<br />
highway on the east<br />
- Developing industrial areas on the<br />
north, south and west.<br />
- Internal city roads to the north,<br />
south and west.<br />
• Approach through the Delhi –<br />
Mumbai highway<br />
• Site selection criteria:<br />
- Linkages to the city<br />
- Employment generating industrial<br />
areas in the surroundings.
Existing features:<br />
• 1.85 hectares allotted for<br />
existing light industries.<br />
Geographical features:<br />
• Flat site<br />
• A natural water channel<br />
running diagonally across the<br />
SW corner.<br />
• Top strata of the black cotton<br />
soil 2-2.5 m thick.<br />
• Gradually sloping (Gradient :<br />
1:110 approx.) towards the<br />
north-west corner.
Township level:<br />
•The aim was to create a central spine. The master plan was informal with<br />
interlinked space of cultural context, maintenance of hierarchy of road,<br />
open spaces, a central location of basic community services.<br />
•The central spine was a focus of the converging six sectors<br />
Six Sector level:<br />
•This enabled segregation of pedestrian and vehicular movement, good<br />
distribution of built and unbuilt spaces by promoting interactive land use.

ROADS<br />
• Segregation of vehicular and<br />
pedestrian traffic<br />
• Offsets break visual monotony<br />
• Hierarchy is based on the<br />
volume of the traffic and<br />
activities<br />
•The roads suit human scale<br />
•Use of cul-de-sacs to avoid<br />
traffic
CIRCULATION AND LINKAGES<br />
For clear segregation of vehicular<br />
and pedestrian traffic:<br />
•Vehicular access in the form<br />
rectilinear and formal roads in the<br />
hierarchy of 4.5m wide to 15m<br />
wide road draw the vehicles<br />
outwardly.<br />
•Pedestrian access in the form of<br />
informal interlinked open spaces<br />
draws people inwardly.<br />
Vehicular roads<br />
Informal pedestrian pathways and open<br />
spaces
HIERARCHY OF OPEN SPACES<br />
• Interlinked informal spaces<br />
• Continuous system of open spaces is<br />
provided<br />
• Staggered roads create spaces for<br />
community congregation<br />
• A single large open space is avoided<br />

CLIMATE RESPONSIVE FEATURES<br />
• Most of the plots small in size and clustered in low rise blocks<br />
• Longer side façade oriented in the north-south axis to reduce the solar<br />
radiation on the building.<br />
• Each house has minimum exposure to wall surface and a common wall.<br />
The north south orientation of<br />
clusters<br />
The building height to street width<br />
ratio is such that streets are<br />
shaded except when the sun is<br />
overhead
CLIMATE RESPONSIVE FEATURES<br />
• The two openings on the north and south permit light and cross<br />
ventilation.<br />
• Courtyards within the houses, cul-de-sacs, public squares and small<br />
activity areas shaded adequately by adjacent buildings.<br />
• Use of locally available building materials.<br />
• Topography used for orientation of major infrastructure network and<br />
spatial organization.

SITE AND SERVICE SCHEME OF DESIGN<br />
•In this scheme services like<br />
water tap, toilets and street lights<br />
and a plinth are provided around<br />
which houses can have different<br />
configurations.<br />
•Longer side of a block of row<br />
house was oriented north south<br />
to reduce solar radiation<br />
•Provision of vertical expansions<br />
•Housing was seen more as a<br />
process than a product
SERVICES<br />
SITE AND SERVICE APPROACH<br />
• Cost-effective<br />
• Progressive development of facilities.<br />
• Houses built by the people themselves to<br />
suit their needs.<br />
• Each family provided with a plot having a<br />
water tank, sewerage connection, paved<br />
access with street lighting, storm water<br />
drainage<br />
• Service cores - key to this site and<br />
service scheme.<br />
- nuclei around which<br />
houses were built.<br />
• Houses were clustered in groups of 10.<br />
• Septic tank provided for every 2 clusters.<br />
• Water drawn from 3 local reservoirs.<br />
•To economize, 20 toilets are connected to<br />
1 manhole.<br />
• One service line serves four rows of<br />
houses
SEWERAGE SYSTEM<br />
• Major alternatives:<br />
- Sewer-less sanitation.<br />
-Conventional sewerage system.<br />
• The soil being impermeable<br />
black soil of 2m depth,<br />
conventional sewerage system<br />
was adopted.<br />
• Designed after thorough<br />
analysis of topography –<br />
naturally slopes towards NW<br />
• Higher income groups, using<br />
more water were located at high<br />
ground level to generate large<br />
flow..<br />
• Lower income groups, using<br />
less water located at lower<br />
ground level<br />
• This resulted in 10-15%<br />
savings.
TREATMENT SYSTEM<br />
• For conveyance system, a wet well and lift station was constructed near<br />
the final manhole.<br />
• Oxidation pond<br />
- located on the NW corner of the site.<br />
- removes biological oxygen<br />
- simple in operation<br />
- effluent suitable for disposal<br />
STORM WATER DRAINAGE SYSTEM<br />
• Very efficient and facilitates healthy and clean living.<br />
• Combination of underground and surface drainage system.<br />
• Underground used for wider roads<br />
• Surface drainage used for internal roads<br />
ELECTRICITY<br />
• High income and middle-income groups were provided with overhead<br />
cables.<br />
• Economically Weaker Sections were provided with underground cables
CONSTRUCTION DETAILS<br />
•Foundation: Under rimmed piles in concrete, cast in situ locally was used<br />
as the soil was black cotton soil.<br />
•Structural members: Reinforced concrete plinth beams, load bearing<br />
brick walls, reinforced concrete slabs.
• Exterior finishes: Bright colour in the façade, railing, grills and cornices<br />
seen in the old houses of Indore used in some houses in the township.<br />
• Residents were free to use any material like brick or stone that were<br />
locally available
LANDSCAPE<br />
• Landscape and green areas include flowering and shade giving trees<br />
with thick ground cover, including lantana, an ever-green tree , that<br />
requires little maintenance.<br />
• Trees include casuarinas, bottle brush and eucalyptus
• Consistency in every aspect<br />
• Staggered roads, prevent<br />
thorough traffic, reduce<br />
speed of vehicles<br />
• Climate responsive and site<br />
responsive design<br />
CONCLUSION<br />
• It understands the traditional Indian habits<br />
• Planning and design is in accordance with<br />
the prevailing socio-economic and<br />
technological conditions<br />
• Cost –effective construction materials and<br />
techniques have been adopted<br />
• Planning is “whole to part” – i.e. From<br />
township level to dwelling unit level.<br />
• Accessibility has been an essential factor for<br />
designing.
