Sixty years after his death, Frank Lloyd Wright’s Circular Sun House, also known as the Norman Lykes House, was the last home design he worked on before he died in 1959. Built in 1967 and later restored in 1994 by his apprentice John Rattenbury, the 3,095-square-foot, three-bedroom, three-bath contemporary house is located in Phoenix on 1.3 acres on the edge of the Phoenix Mountains Preserve. It will go to auction on October 16th with no reserve. Wright designed over 1,000 structures during his 73-year career including many of America’s most famous buildings such as Fallingwater, the Guggenheim Museum and the Johnson Wax Headquarters.
