About This Home
Fold House is a striking new construction residence by award-winning women-led architect duo Artifact Collaborative, set dramatically in the lower Berkeley Hills. West-facing windows and doors frame sweeping 180-degree views of San Francisco and the Golden Gate Bridge. The home’s name reflects its defining design concept—interlocking planes and articulated volumes—expressed through sculptural two-story floating staircases and a distinctive folded roofline. A triangulated clerestory window draws in abundant natural light throughout the interiors. Thoughtfully designed to inspire and endure, Fold House offers a forward-thinking, all-electric lifestyle with solar PV and battery, high-efficiency heat pumps, EV charging, seismic-resistant foundations, and fire-hardened construction with standing seam metal roofing, plaster exterior, and a full fire sprinkler system. A rare architectural offering where form and function exist in perfect balance. With panoramic vistas and light-filled interiors, every day feels extraordinary. This is Berkeley Hills living at its very best.
