DISTRIBUTION OF AMENITIES
•Community facilities grouped in
local sub centers.
•Formal organization
•Community amenities distributed
evenly
•Informality created
•Accessibility improved
•Lower level community facilities
organized in green spaces
•Even distribution
•Maintains link with town centre
•Pedestrian access easier.

THE NEIGHBOURHOOD CONCEPT
Concept
•Slum development project
•Inspiration from existing slum
settlements in Indore
Characteristics
•Mixed and multiple land use
•Formation of small
neighborhoods and houses
extending to the outdoors.
•Small shops operating within
congested areas.
•Trees planted in public places
•Streets accommodating social,
economic and domestic activities.

SITE ANALYSIS
•Urban Indore city 214 sq. km.
•Major development along Delhi –
Mumbai highway running through the
city in the north south direction
•Surroundings: -Delhi-Mumbai
highway on the east
-Developing industrial areas on the
north, south and west.
-Internal city roads to the north,
south and west.
•Approach through the Delhi –
Mumbai highway
•Site selection criteria:
-Linkages to the city
-Employment generating industrial
areas in the surroundings.

Existing features:
•1.85 hectares allotted for
existing light industries.
Geographical features:
•Flat site
•A natural water channel
running diagonally across the
SW corner.
•Top strata of the black cotton
soil 2-2.5 m thick.
•Gradually sloping (Gradient :
1:110 approx.) towards the
north-west corner.

Township level:
•The aim was to create a central spine. The master plan was informal with
interlinked space of cultural context, maintenance of hierarchy of road,
open spaces, a central location of basic community services.

•Segregation of vehicular and
pedestrian traffic
•Offsets break visual monotony
•Hierarchy is based on the
volume of the traffic and
activities
ROADS
•The roads suit human scale
•Use of cul-de-sacs to avoid
traffic

CIRCULATION AND LINKAGES
For clear segregation of vehicular
and pedestrian traffic:
•Vehicular access in the form
rectilinear and formal roads in the
hierarchy of 4.5m wide to 15m
wide road draw the vehicles
outwardly.
•Pedestrian access in the form of
informal interlinked open spaces
draws people inwardly.

HIERARCHY OF OPEN SPACES
Access to open spaces in minutes
•Interlinked informal spaces
•Continuous system of open spaces is
provided
•Staggered roads create spaces for
community congregation
•A single large open space is avoided

CLIMATE RESPONSIVE FEATURES
•Most of the plots small in size and clustered in low rise blocks
•Longer side façade oriented in the north-south axis to reduce the solar
radiation on the building.
•Each house has minimum exposure to wall surface and a common wall.
The north south orientation of
clusters
The building height to street width
ratio is such that streets are
shaded except when the sun is
overhead

CLIMATE RESPONSIVE FEATURES
•The two openings on the north and south permit light and cross
ventilation.
•Courtyards within the houses, cul-de-sacs, public squares and small
activity areas shaded adequately by adjacent buildings.
•Use of locally available building materials.
•Topography used for orientation of major infrastructure network and
spatial organization.

Plan showing varied houses with backyards (private open spaces)

•In this scheme services like
water tap, toilets and street lights
and a plinth are provided around
which houses can have different
configurations.
•Longer side of a block of row
house was oriented north south
to reduce solar radiation
•Provision of vertical expansions
•Housing was seen more as a
process than a product

CONSTRUCTION DETAILS
•Foundation: Under rimmed piles in concrete, cast in situ locally was used
as the soil was black cotton soil.
•Structural members: Reinforced concrete plinth beams, load bearing
brick walls, reinforced concrete slabs.

•Exterior finishes: Bright colour in the façade, railing, grills and cornices
seen in the old houses of Indore used in some houses in the township.
•Residents were free to use any material like brick or stone that were
locally available

LANDSCAPE
•Landscape and green areas include flowering and shade giving trees
with thick ground cover, including lantana, an ever-green tree , that
requires little maintenance.
•Trees include casuarinas, bottle brush and eucalyptus

CONCLUSION
•It understands the traditional Indian habits
•Planning and design is in accordance with
the prevailing socio-economic and
technological conditions
•Cost –effective construction materials and
techniques have been adopted
•Planning is “whole to part” –i.e. From
township level to dwelling unit level.
•Accessibility has been an essential factor for
designing.
•Consistency in every aspect
•Staggered roads, prevent
thorough traffic, reduce
speed of vehicles
•Climate responsive and site
responsive design
