Wright spent much of the latter part of his career designing functional, cost-effective Usonian houses like the Rosenbaum House, a 1,540-square-foot residence built at a cost of $12,000. In 1948, Wright designed an addition to the house, providing a larger kitchen, a playroom and guest quarters. Southern cypress and red brick from northern Alabama clay form a nearly solid wall on the street side of the house. The rear is remarkably open, with floor-to-ceiling windows and doors opening to the terrace, a Japanese garden and the woods beyond. The house underwent a complete restoration and was opened as a city-owned museum in 2002 with regular tours.
