The Golden Gate Bridge and the city of San Francisco are seen in the distance in this view from a 15,000 square-foot custom built home on Belvedere Island in Marin County, California, U.S., on Wednesday, Dec. 19, 2012. The builder couldn't find a buyer for the brand-new waterfront mansion he listed in January for $45 million. He hopes one will turn up at a Dec. 30 auction, where the starting bid will be $25 million. Photographer: David Paul Morris/Bloomberg
