A rustic modern Tahoe-inspired retreat with direct Mt. Diablo views, expansive windows, elevated materials, energy efficiency, and everyday livability. 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. 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 reimodeled 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 Walnut Creek, BART, trails, the Iron Horse Trail, and 680. Open Sat 1-4pm Sun 2-4pm
