21. Waterfall House
In 1935, architect Frank Lloyd Wright designed this incredible house (Fallingwater) that re-ignited his architectural career. It’s a home that presents architecture conforming to nature. In an effort to appease his clients’ requests for a house that accommodates large groups for parties, as well as three bedrooms and a guest house, on a plot of land that was far too small for an ordinary design, Wright designed a cantilevered home that was built partially over a waterfall on Bear Run in Pennsylvania.

22. Gypsy Wagon
This 160-square-foot micro home on wheels is designed to look like something from the past or perhaps a work of fiction. Its unique style is the result of hard labor and expert salvaging. The entire compact home is created through recycled and reclaimed materials. Even the furniture and appliances inside the mobile home are all found and reused objects.
