    Living Large

    These days, buyers dreaming of moving into large homes may be disappointed to find that properties are getting smaller, a result of modesty in the economic downturn and increased attention to efficient homes. The average size of single-family homes declined slightly to 2,377 sq. ft. last year from a peak of 2,521 sq. ft. in 2007, according to U.S. Census Bureau estimates. By 2015, builders surveyed by the National Association of Home Builders expect the average home to shrink by another 10 percent to 2,152 sq. ft. Luckily for those who won't settle for a place with less than seven bathrooms, colossal homes have not disappeared. Listing data from Altos Research, a real-time real estate data company based in Mountain View, Calif., show many residential areas outside of urban centers have an ample supply of large homes, most measuring at least twice the national average. Based on the median square footage of homes for sale in 20,000 Zip Codes and 200 metro areas, Greater Pittsburgh had the largest number of areas with big houses, followed by Rancho Santa Fe, Calif., and Coral Gables, Fla.
