The Norman Lykes House, also known as the Circle Sun House, was one of just 14 circular homes designed by famed architect Frank Lloyd Wright.
“Aimee and Norman Lykes commissioned Frank Lloyd Wright to design their house in Phoenix in 1959. It was the last structure built for an original client from Wright’s designs,” Barbara Gordon, the executive director of the Frank Lloyd Wright Building Conservancy, told Insider.
The house was constructed in 1967 under the supervision of architect John Rattenbury, who had worked with Wright on its design, Gordon said.
“It is reportedly one of the last designs Wright worked on before his death in 1959,” she added.
