If India needed any more proof that it was in the midst of a huge housing boom, it got in this week's GDP data, heightening expectations that the industry will continue to power the economy for years to come. The construction sector grew 13.3% in July-September from a year earlier, up from 7.9% in the previous quarter and its best performance in five quarters, the data released on Thursday showed. That helped India expand at a forecast-beating 7.6%, making it one of the world's fastest-growing major economies.
