PHOENIX, ARIZ. — The last house designed by Frank Lloyd Wright, the Norman Lykes’ House, sold for $1,677,500 at a live, public auction conducted on October 16 by Heritage Auctions. The auction was held inside the iconic contemporary home with no minimum starting bid and was sold without reserve.

Bidding opened at a conservative $750,000 and response from the 19 registered bidders was immediate. The price was quickly bid to $1.5 million before ending at $1.67 million.

The winning bidder does not wish to be identified at this time, but the winning bid came from a man who lives out of state who plans to keep the home intact and use it as a vacation home, director of luxury real estate for Heritage Auctions, Nate Schar, said.

Also known as “The Circular Sun House,” the iconic, 3,095-square-foot estate is located on more than 1.3 acres on the edge of the Phoenix Mountains Preserve.

The home was sold fully furnished, complete with the original furniture and fixtures Wright designed specifically for this house. It was commissioned by the Lykes family and required eight years to complete.

A hallmark of Wright design, the home was built to embrace organic architecture and take full advantage of the views afforded by its mountainside location. Its curved lines in the home play off the curves of the Phoenix Mountains. Wright designed the home so that the windows would never see direct sun, yet the house would remain flush with natural light. For further information, www.ha.com or 877-437-4824.
