Living Large in 117 Square FeetForget the McMansion. Tumbleweed Tiny House Company offers 21 floor plans for houses starting at 117 square feet.

Steve Weissmann, a California restaurateur and real-estate investor, was already living in just 400 square feet of space when he met Jay Shafer, founder ofTumbleweed Tiny House Company. Shafer was a leading voice in a growing movement that encourages people to live in tiny homes. His fledgling company sold books and building plans for complete residences that started at 65 square feet.

Weissmann so loved the stylish Tumbleweed homes that in 2007 he bought into the venture and became its president. He quickly realized that the wee company needed a big makeover. "When I joined Tumbleweed," he says, "it was more of a product than it was a business."
