A modern architectural triumph in Old Palo Alto. Conceived by master architects Steven Ehrlich, FAIA, and Takashi Yanai (EYRC), custom estate spans 8,000+ sq ft across three elevator-served levels, merging Bauhaus discipline with California modernism. Anchored by a 30-inch cast-concrete spine wall, German Rheinzink ceilings, and bespoke Zeluck mahogany pocketing doors that dissolve into four landscape quadrants by CMG. The main level features 11.5-ft ceilings, an expansive Great Room, an acoustic formal dining room, a Bulthaup kitchen with Viking and Miele appliances, and a private executive study. Upstairs features a primary retreat, 3 en-suite bedrooms, loft library, and a suspended glass bridge. The sunlit lower level delivers an art gallery, wine cellar, tasting room, and private cinema with Sony 4K laser projection and CAT audiophile sound. Engineered to commercial standards: 14-zone radiant heat, 5-zone Trane A/C, 400A service with isolated AV panel, 18kVA UPS backup, Acme elevator, lap pool with subterranean vault, and 2-car garage with 3 EV chargers. Published globally on five continents, including Architectural Digest and GA Houses, and winner of the Custom Home Grand Award. Replacement Cost: $61M total budget (excluding land/FF&E) to replicate this home today.
