Every home Frank Lloyd Wright designed is special. But you have to imagine the one he built for his son carried a little more weight. If you’re not sure that’s the case, drop the $12,950,000 and find out, as the home is on the market. Constructed in 1952, the concrete abode sits in Phoenix, Arizona, on 5.9 acres of land and is highlighted by the circular main area that offers incredible views of the Camelback Mountains. You’ll find plenty of expose concrete throughout the home, a 360-square-foot guesthouse, and one hell of an eye-catching carpet. The home was occupied by David, Frank Lloyd Wright’s son, and Gladys, his wife, until they both passed away, and it’s commonly referred to as the David and Gladys Wright House. We can’t afford the house, but we’re very interested in an affordable version of the rug.
