We featured Jack Olsen’s multifunctional 1972 Porsche 911 during the very early days of Petrolicious films, and for this episode of Master Mechanics we met up with Jack again, this time to put the spotlight on the other Swiss Army knife that he’s built. Like the 911 that lives inside of it, the 12-Gauge Garage—named after the thickness of the steel cabinetry within—is a study in maximum utility extraction. In this case, a typical 20’ x 20’ two-car garage in Los Angeles that’s been rethought and redesigned to function as a respectable workshop for Jack’s Porsche.
