Home Delivery

Prefab houses are as varied as the people who purchase them: There are round homes, Georgian homes, log homes, conventional homes and detached studios. But they all have one thing in common-most prefab homes are an energy-efficient and environmentally sound alternative to traditional homes. In prefab factories, excess wood is used for other projects. "In 'stick building,' [traditional on-site building] material is wasted and tossed into a dumpster," says Tony Gacek, executive director of the Building Systems Councils of the National Association of Home Builders. Prefab homes also tend to be more efficient and better insulated post-construction and often feature Energy Star-rated appliances.
