This modernist hillside masterpiece reveals dynamic views of the Briones Reservoir and vistas beyond. Located on 1+ acre on a private road in the coveted Sleepy Hollow neighborhood of Orinda, this 5-bedroom, 5-bathroom home was designed with one purpose: to live and entertain harmoniously amidst the natural beauty of the trees and hillside. Featuring oversized windows, viewing decks, and terraces, the home's versatile layout blends indoor and outdoor living. In the living room, sliding walls of glass open to a spacious deck with sunset views of the reservoir. At the heart of the home, an open-layout kitchen is highlighted by an 18' waterfall island of engineered stone, complemented by a glass-enclosed wine cellar. The dining area accommodates a 12-person table and is set against a backdrop of sliding glass walls leading to the expansive, multi-level entertaining deck. The primary suite includes a spa-like bath, private deck, and outdoor hot tub with water views. A 1-bed, 1-bath au pair unit with a private entrance is located on the lower level. Advanced infrastructure includes a Savant system with iPad controls, a multi-zone security system, triple-zoned HVAC, dual tankless water heating systems, and irrigation. Property is owner occupied.
