Average sizes of flats in most big cities have shrunk in the last five years, largely driven by realtors’ efforts to tap a larger customer base, especially millennials who have shown preference for affordable homes at good location over larger flats in the far-flung suburbs. According to real estate consultancy firm Anarock, properties costing below Rs 40 lakh saw 23% fall in average sizes in the 2014-2018 period. In absolute terms, sizes reduced from 750 sqft in 2014 to 580 sqft in 2018 for such houses.
