This case study examines the CIDCO Housing development in Belapur, Navi Mumbai, which was constructed between 1988-1993 to provide low-cost housing. The development consisted of 1048 apartments arranged into clusters on a 9.5 hectare site. The units ranged in size from 20-100 square meters to accommodate different income levels. The housing was designed with a network of courtyards, pathways, and terraces to foster community interaction while maintaining privacy.
