This document discusses low cost housing and approaches to sheltering those with low incomes. It notes that low cost housing aims to save money on construction while maintaining building quality by using locally available, cheap materials and improved construction skills and technology. However, lower construction costs can mean higher utility bills from wasted energy. The document also outlines some of the challenges to developing low cost housing in India, such as land shortages, rising construction costs, lack of access to financing, and regulatory issues. It provides examples of materials that can reduce housing costs and recognizes the contributions of architect Laurie Baker to sustainable, low cost housing design.
