Andreas collaborated deeply with the architect to develop the resulting two-story, 1,120-square-foot unit, which is "much more than a garage," says Zünkeler. "It’s an extension of the yard." Glass doors surround the ground floor, creating a seamless visual flow between courtyard and parking space. For even more room to play, the family can move their camper van out of the way to use the light and airy open room as a studio space.
