How space is distributed in a new home is a frequently asked question. To collect information on this, NAHB (the National Association of Home Builders) recently surveyed its single-family builder members. The average percent distribution of finished space in the typical new home built by NAHB’s members is illustrated below.
In addition to an average breakdown of space in all new homes, NAHB looked at the breakdown for a small home (based on averages for home sunder 2,000 square feet) and a large home (based on homes with at least 3,000 square feet).
Findings include the following:
Bedroom space accounts for just under 29 percent of floor space in new homes, irrespective of the overall size of those homes.
Bathroom space is allotted 12.3 percent of total floor area on average, with more space allotted in larger homes, and less in smaller ones.
The share of space covered by the laundry room- which is present in the vast majority of homes, irrespective of their size- is 3.7 percent and varies only to a minor extenct with the size of the home.
Entry foyers account for 3.4 percent of the finished area on average.
Kitchens get about 11.9 percent of the space in small homes, versus 11.1 percent of the space in larger ones.
Dining areas account for 7.8 percent of the space in small homes and 7 percent of the space in larger ones.
The family room accounts for just over 11 percent of floor space in small, average, and large size homes, while the living room accounts for nearly 12 percent of the space in the small home and 7.5 percent in the large one.
Complete details, including tables showing how often builders include various types of rooms in new homes and the size of rooms in square feet, are available in the October 1 Special Study published by NAHB on HousingEconomics.com.
