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.

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.
