Rochester, New York
This may look a still from a science fiction film, but it's actually just a mushroom-looking abode in upstate New York. Designed by architect James H. Johnson in the late 1960s as his take on organic architecture, the elevated structures are connected by a network of halls. A "cave" addition, made in 2002, features intricate interior tile mosaics on walls and floors. Though the house is commonly known as the Pod House, or even the Mushroom House, its design was inspired by the Queen Anne's lace plant.
