Prefabricated homes have come a long way since the days when modular meant mobile to home buyers. Today, buyers can find a wide selection -- from studio units to single-family homes -- for a variety of prices. The cost per square foot for a typical modular home is $76.80, according to the National Association of Home Builders. The average stick-built home costs $94.34 per square foot.

The prefab houses we profile here are far from average and definitely aren't cheaper quality. They range in size from 2,200 to 4,400 square feet, are constructed using high-end "green" materials and, in some cases, have been custom-built to owners' exact specifications. Take a look.
