It's a sci-fi geek's wet dream: A 2,000-square-foot UFO house replete with three bedrooms, two full bathrooms, a bar and an entertainment area. It's actually kinda sweet. All of the rooms are round and there's a retractable staircase should you ever find yourself besieged behind its sturdy concrete and steel walls (unfortunately, the staircase is broken and remains in the down position, so you'll have to fix that).
