Toll Brothers is a national builder of new multigenerational homes with flexible design options. According to their website, the U.S. Census Bureau defines a multigenerational home as a household with more than two adult generations living under the same roof or grandparents living with grandchildren under age 25. Toll Brothers states multigenerational homes allow families equal space to live harmoniously under one roof, with distinct architectural design and open floor plan concept providing versatile space where grandparents can spend time with grandchildren while parents prep dinner.
