The Robert Llewellyn Wright House in Bethesda, Maryland, is a historic Frank Lloyd Wright design created in 1953 and completed in 1957 for his son Robert Llewellyn Wright. A two-story, 1,800-square-foot concrete-block house, it is one of only two Wright-designed structures in Maryland. Its Usonian plan uses intersecting and concentric hemicycles to create an unusually fluid arrangement of space. Earlier designs were set aside because they were too costly, and the final version adapted Wright’s vision to practical construction. Built on a sloping site above a stream, the grounds were landscaped in 1960 by Lloyd Wright.
