◦Neighbourhood an “area” within which residents
share common services, social activities and facilities
in vicinity of the dwellings
IDEA OF NEED:
◦The necessity thought was because of the
automobiles in the early 20
th
century
◦Road sense was not proper with the social conscious,
thus street fatality rayes were increased
◦Idea was to generate islands locked amidst a wide
sea of vehicular traffic, a dangerous obstacle which
prevented children and adults from safely walking to
nearby playgrounds and amenities
◦Ultimately , if evolved to serve a much broader
purpose, of providing anneighbourhood

were around these design ideals

2.Place arterial streets along the perimeterso that they
define and distinguish the “place” of the
neighbourhood
3.Design internal streets using a hierarchy that easily
distinguishes local streets from arterial streets
4.Restrict local shopping areas to the perimeter
5.Dedicate at least 10% of the neighbourhood land
area to parks and open spaces
OPEN SPACES

8. Principles of neighbourhood unit
1.Size:
◦The town is divided into self contained units or sectors of population
◦This is further divided into smaller units called neighbourhood with 2000 to 5000 based on
the required of one primary
◦The size of the units is therefore limited to about 1 to 1.5 sq within walkable distance of 10
to 15 min
2.Boundaries:
◦The unit should be bounded on all its sides by main roads enough for traffic
3.Protective strips:
◦These are necessary to protect the neighbourhood from traffic and to provide suitable
facilities for developing parks, playgrounds and road widening scheme in future.
◦These are called Minor Green Belts

9. 4.Internal streets:
◦The internal streets are designed to ensure safety to the people school going children in particular
◦The internal streets should circulate throughout the unit with easy shops and community centres
5.Layout of buildings:
◦To encourage neighbourhood relation and secure social stability and balance
◦The houses to suiy the different income group should be provided single family houses, double family
house, cottages ,flats ,etc.
6.Shopping centres:
◦Each shop should be located on the circumference of the unit, preferably at traffic junctions and
adjacent to the neighboucircumferenc
7.Community centres:
◦Each community will have its centre with social cultural and recreational amenities
8.Facilities
◦All public facilities required for the family, for their comfort and convenience should be within easy reach
◦These include the primary school, temple , club , retail shop, sports hub
◦These should be located within 1km in the central place so as to nucleus to develop social life of the unit

12. Grouping of three neighbourhood
units served by a high school and
one or two major commercial
centres, the radius for walking
distance to these facilities being
one mile clarence Stein
determination of proper areas to
be included in the neighbourhood
Elementary school is the centre of unit and within a
one half mile radius of all residents in the
neighbourhood. A small shopping centre for daily
needs is located near the school. Most residential
streets are suggested as dead end roads to
eliminate though traffic , and park space flows
through the neighbourhood ina manner reminiscent
of the res burn plan

13. Neighbourhood unit of the 1920 New York Regional plan, Clarence defines the
neighbourhood as a component of a town and defines its size based upon a 5 min
walking radius . The radius is measured from the centre and the centre holds the cultural
uses such as a school
In 1920’s and 1940’s the centres and anchors of neighbourhood’s were the schools.
More recently, the quarter mile walking radius haß been expanded to a half mile with
the addition of a transit hub.
Traditional neighbourhood size works well in the towns, village , and urban city scales.

15. Importance:
◦Neighbourhood planning is quickly
becoming a high priority for the city
planning department, and even
hjman service providers
◦Neighbourhood planning is effective
and provide inspire those creative
strategies that can increase the
capacity of residents in chatting out
their shared future
◦It’s a vision of better future
