The Thunderbird Heights neighborhood in Rancho Mirage, California is so hoity-toity that rumors that the president is moving in actually seem plausible (but ultimately are untrue). It's in that ultra-wealthy corner of Rancho Mirage that this effortlessly hip spaceship house is located. The circular house includes a circular patio surrounded by a circular pool. (Wait, is there a theme here?) The interior feels kind of like it could be the outside, thanks to large expanses of curved, floor-to-ceiling windows that afford views of the 1.17-acre property. Minimal white decor and terrazzo floors run throughout the house, which has a 90-foot diameter and four bedrooms. It's now listed for $4.5 million.
