First, developing EWS flats requires a hefty quantum of direct subsidies as well as cross-subsidisation. The minimum cost of developing a 400 sq ft flat at a realistic construction cost of ₹ 3,000 per sq ft is ₹12 lakh, excluding land. Households usually contribute around ₹3 lakh, leaving a subsidy gap of ₹9 lakh. The subsidy required increases when land cost is factored in. The required subsidy has to come from government funding and/or cross-subsidisation supported through the “affordable housing” policies and slum redevelopment schemes. But the quantum of subsidy required is daunting and hence EWS flats are not developed at scale. It deters private developers from venturing into EWS projects. Public developers have limited bandwidth, and government coffers have limited funds. As a result, few EWS flat projects are sanctioned and undertaken.
