New homes 5,000 square feet or more increased both as a share of all new construction and in absolute number  in 2015, according to the Census Bureau’s Survey of Construction. In 2015, the share of new homes this size reached a post-recession peak of about 4% of new homes started nationwide, a number of around 28,000 units. The extent to which the 5,000+ square foot homes have recovered through the end of 2015 – to roughly to where they were in 2008, shows growing strength at the top of the market.
