Designer Hans Warner remodeled the home’s existing 24- by 24-foot garage (above, left). For budgetary reasons, the team needed to keep the foundations of the old structure. “At that point it became more of an experiment in how far could we push the geometry to generate something that truly had barn- like proportions,” he says. The first floor contains a garage and entrance passage to the front door, and above it there is a bunkroom for visiting children.
