There's a trend in US housing, 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 many cases, to spaces no larger than 500 square feet. `Tiny House, Big Living' celebrates this movement, spotlighting the small-dwelling dreams-turned-reality for couples, families and singles across the country. They either take on the builds themselves or hire contractors who cater to unique personalities by creating custom furniture and layouts. Either way, viewers follow the adventures through the construction process until the minihomes are complete.
