There's a trend in the U.S. housing market, albeit a very small one. Drawn to the prospect of financial freedom, a simpler lifestyle, and limiting one's environmental footprint, more buyers are opting to downsize -- in some cases, to spaces no larger than 300 square feet -- and this series celebrates the "tiny house" movement. Hosts and renovation professionals John Weisbarth and Zack Giffin travel across America to show ingenious small dwellings and their creative inhabitants. They also help families design and construct their own dream minihomes.
