Circular Sun House, the last residence designed by America's pre-eminent 20th-century architect Frank Lloyd Wright, will be offered at auction next month. One of 14 circular homes Wright created, and his last design before he died in April 1959, the residence will be sold at a live, on-site unreserved auction in the desert outside Phoenix on Oct. 16.

The estate was previously listed at $3.6 million in 2016 and later for sale at $2.65 million with The Agency. Heritage Auctions will sell the property without a reserve price.

At age 91, Wright designed the Arizona house for Norman and Aimee Lykes, prior to his completion of the iconic Guggenheim in New York. Known for pioneering the Prairie School movement, Wright created a low profile, with clean lines and elements that blend into the Palm Canyon views at Phoneix Mountains Preserve.

The 3,095-square-foot, two-story house comes with mid-century furnishings, including some designed by Wright.

Wright's own beloved 1930s-era Sonoran desert home, Taliesin West, where he wintered until the end of his life, is now a museum, architecture school and UNESCO World Heritage Site.
