Modi seeks to construct 20m homes across India

Prime Minister's ambitious plan could hold the key to boosting nation's economic growth

Faced with increased living costs in 2012, Suresh Kumar sent his wife and children back to their village in eastern India and took in two migrant workers to share his one-room apartment on the fringes of Delhi.

That brought his rent down to 3,000 rupees ($50), about a third of what he earns each month as a chauffeur in India's capital. Despite that, he still needs to dodge puddles of sewage in the neighborhood, battle with an erratic power supply and vie with about 10 other people to use an external bathroom.
