A style of residential architecture created in the 1930s by Frank Lloyd Wright (1867–1959). Usonian houses were designed to be efficient and affordable, single-storied, constructed of natural materials, and integrated with the landscape. Usonian houses typically featured open floor plans, central hearths, built-in furniture and shelving, skylights, and cantilevered carports. Beginning in 1936, Wright designed about 60 Usonian houses.
