FOREWORThis Indian Standard was adopted by the Bureau of Indian Standards after the dra ft finalized by the

o u s ~ n Sectional o m m ~ t t e e had been approved the Civil Engineering Division Council.Cluster planning is recognised to be consistent with traditional Indian life style. This bas also been anaccepted traditional practice all over the world. In the recent years however cluster planning has beenlargely neglected. The traditional changes of the modern age which made people more individualisticand self centred the large city anonimity the loosening of family and community ties the advent ofthe automobile and the desire to bring it almost in the house tended to make cluster planningirrelevant.In the recent years there has been an upsurge of projects to resettle slum dwellers and provide housingfor the urban poor. Several studies have been carried out of spontaneously developed settlements. Wehave now rediscovered the virtues of low rise high density development in the context of affordabilityand incremental growth. There have been number of innovative projects being developed. The clusterconcept has been accepted now as economic necessity and desirable socially to promote desired lifestyle.Cluster planning has proved to be a powerful urban design tool yet number of conventional byelawprovisions such as set back and coverage binder efficient planning based on cluster concept. It hastherefore become necessary to devise guidelines that willpermit imaginative cluster planning.The composition of the committee responsible for the formulation of this standard is given inAnnex A.
