New homes in 2015 will be smaller, greener and more casual.

The average home will be 10 percent smaller in 2015 than the average size of single-family homes built in the first three quarters of 2010.

In addition to floor plan changes, 68 percent of respondents said that homes of the future will include more green features and technology, including low-emissivity windows; engineered wood beams, joists or tresses; water-efficient features such as dual-flush toilets or low-flow faucets; and an Energy Star rating for the whole house.

Even among homeowners whose house has lost value in the current recession, 82 percent of homeowners who say their home is worth less now than before the recession still believe that homeownership is the best long-term investment a person can make.

The top interior projects for resale value included an attic bedroom and a basement remodel. Both add living space without extending the footprint of the house. An attic bedroom addition is estimated at more than $51,000 and recoups an estimated 72.2 percent nationally upon resale; a basement remodel can cost upwards of $64,000 and recoups an estimated 70 percent.
