OWATONNA — A Minnesota guesthouse designed by architect Frank Gehry that was once valued at $4.5 million has sold for $905,000 at auction in Chicago.

The Star Tribune reports the Winton Guest House was estimated to sell for as much as $1.5 million Tuesday. An auctioneer declared the building sold to an unidentified telephone bidder for $750,000, plus fees, after less than five minutes of bidding.

The guesthouse currently sits in a field outside Owatonna. It was sold by the University of St. Thomas, which moved the house from its original location overlooking Lake Minnetonka after acquiring it as a gift in 2007. It was designed by Gehry for Twin Cities art patrons Mike and Penny Winton.

The new owner, who is from outside Minnesota, has to move the house.
