Shrinking space in housing units where a 1-BHK unit squeezed into less than 300 sqft or a 3-BHK flat is not exceeding the 700 sqft mark is turning out to be a big draw for top developers who entered in the affordable housing sector in and around Pune metropolitan region. This is said to be so because of the score of incentives available for the developers and they are opting for such nano units. They are not just only enjoying the tax benefits but also with the opportunity to get going in a market that is taking baby steps to recovery after a prolonged slowdown. In the region the top developers, who have so far only focused on big ticket projects in residential and commercial real estate, are increasingly announcing their foray into affordable housing sector to make the most out of the available benefits, said sources.
