Arizona

It took less than five months for architect David Hovey Jr. to build this prefab home in Arizona's Paradise Valley, a rectangular pavilion with a shell of laminated glass, a perforated Cor-Ten steel roof, and an indoor courtyard where Hovey Jr.'s family take dips in the Olympic-size swimming pool. Polished concrete floors, Nakashima furniture, and a large black walnut bar are all found indoors.
