A Modern Masterpiece in a Coveted Los Altos Hills Setting. Set along one of the most prestigious and tightly held corridors, 27600 Altamont Rd. offers a rare, fully approved, shovel-ready estate opportunity. Situated on 1.2 acres, the property includes finalized plans and permits from acclaimed Humphreys & Partners Architects, allowing construction to begin immediately, eliminating years of entitlement risk and delay. A rare advantage is the existing residence on site, which may be occupied or leased for income during construction, offering flexibility, carry-cost offset, and an easier financing path. The approved design features a 5,800-square-foot modern main residence with seamless indoor-outdoor living, a gourmet kitchen with a butler's pantry, a private guest suite, a home office, and expansive entertaining spaces. A lower level includes wellness amenities such as a fitness room, sauna, and wine cellar. A separate 1,200-square-foot ADU provides ideal space for guests, multigenerational living, or a private executive retreat. Resort-style grounds include a pool/spa, bocce court, and multiple outdoor living areas designed for privacy, natural light, and west-hill views. Ideally located with easy access to downtown Palo Alto, Los Altos, and nearby open-space preserves.
