The S.F. mansion that made waves In 1962, developers shipped a Pacific Heights mansion across the bay. It was a bold move to create denser San Francisco housing. There was no sequel. It looked like a surreal scene from a Pixar film, more than three decades before Pixar films existed. A Pacific Heights mansion, chain-sawed into two 85-ton pieces, was rolled through several city blocks and then shipped across the bay on a barge to a new home in Belvedere. It was a refugee of a changing San Francisco, captured in 1962 by Chronicle photographers as it floated away from Coit Tower, Alcatraz and the Golden Gate Bridge.
