The Spin MasterCars, tables, massive sculptures--you name it, John Thomson will have it rotating in no time.

A treacherous 200-foot driveway, a $750,000 garage and one too many busted rearview mirrors drove John Thomson into major problem-solving mode.

Back in 2004, Thomson was a successful bond trader in Los Angeles when he built a lavish combination garage, guest house, wine cellar and media room. It was nicknamed the "Garage Mahal," but it had near-fatal flaws: Thomson couldn't get his car out of it without moving his wife's car, and his wife couldn't back out without bashing a mirror or two.
