Property Description
A comprehensive transformation by Alamo-based RSR Development, bringing together sophisticated design, significant structural engineering, and high-quality construction. Direct Mt. Diablo views, expansive windows, and energy efficiency. The entry pivot door sets the tone immediately, opening to the huge view-framing window capturing the mountain through floating maple stair treads. A striking architectural moment designed by noted Architect Martin Hammer. The main living level centers around an open gathering area with soaring vaulted wood ceilings, stunning kitchen representing sea, earth and sky, formal dining, exposed beams, expansive Fleetwood windows, and access to an outdoor seating area overlooking Mt. Diablo. The kitchen anchors the home with quartzite island, Wolf/Sub-Zero appliances, steam oven, custom hood and walk-in pantry. A refined mix of stone, glass, metal, and natural warmth. Extensively remodeled with an emphasis on architecture, systems, and symmetry, the home includes steel beams, double shear, owned solar, updated HVAC, maple hardwood, modern railings, upgraded lighting, and a media room / 5th bedroom. Set on 1.17 acres on one of Alamo’s friendliest streets, the flexible floor plan offers two ensuite bedrooms with one on the main level, two living areas, and easy access to two 2-car garages (total 4). Close to downtown WC, BART, Iron Horse Trail, and 680.
