Raj Rewal designed the Sheikh Sarai housing complex in New Delhi in 1970 as his first large-scale social housing project. The 550-unit complex was structured according to regulations to provide affordable self-housing and technical standards. Rewal drew inspiration from the dense, interconnected urban fabrics and narrow shaded streets of historical cities in Rajasthan like Jaisalmer and Udaipur. The complex features clusters of buildings organized around intimate courtyards and roof terraces, with segregated pedestrian and vehicular access. Materials and construction methods were chosen to be locally sourced and affordable.
