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 homes under 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 allocated 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 extent with the size of the home.
