This striking custom home, designed by San Francisco architect John Klopf, features a modern aesthetic inspired by the simple sophistication of Japanese design. Located in Green Valley Highlands (one of the area's best-kept secrets) on the edge of Suisun Valley AVA, it sits on a serene 1-acre lot at the end of a cul-de-sac. This elegant house is a study in the efficient use of space while providing a comfortable and easy-to-maintain home that is highly livable, indoors and out. An open breezeway between the main house and master bedroom offers a space for outdoor relaxation and transforms the master bedroom into a private sanctuary, while adding to the sense of openness that connects the indoor space with the beautiful outdoor setting--an essential characteristic of the house. Key features include a low-maintenance metal roof, FSC-certified redwood siding, radiant-heated stained concrete floors, and an owned 7.56kW solar system with backup batteries. The expansive 962sf garage, complete with plumbing, heat, storage, and a 240v/50A outlet, provides versatile use. A tool shed provides additional storage for garden supplies. Local activities incl wine tasting, road and mountain biking, hiking, golf, tennis, and Lake Berryessa. Easy access to I-80 & I-680.
