This luxury home in The Colony subdivision of the Canyons has been among the priciest listings in Park City for a while now — last listed at $15.9 million — but Friday it will hit the block at a no reserve auction. The 17,422-square-foot home on 4.63 acres has proven to be a favorite option for celebrities visiting Park City. Taylor Swift, Larry King and Ashton Kutcher and Demi Moore have all rented the home, according to Concierge Auctions, which is hosting Friday's auction. Justin Bieber posted a photo to Instagram from the home's deck just over a month ago. With nine bedrooms (one of those being a bunk room that sleeps eight) and 11 bathrooms, there's plenty of room for celebrity entourages or large family gatherings.
