According to a recent survey of builders and consumers by the National Association of Home Builders (NAHB), by 2015 half of all builders think the living room will be merged with other rooms in the home. Nearly a third say it will vanish entirely. The entryway and dining room will also likely decrease, and the family room will become larger, likely incorporating the kitchen, living room and entryway. The recent housing crisis will lead new home builders to reduce the overall size by more than 200 square feet. Sixty-eight percent of the builders said the homes of 2015 will feature more energy and water efficient systems with an Energy Star rating for the entire house.
