The Berryessa Lake House is a breathtaking fusion of architectural innovation and engineering precision. Situated on 95 acres in Napa County, this award-winning, IwamotoScott-designed residence is a steel & glass marvel offering panoramic views of Lake Berryessa & the surrounding valley landscape. The home's bold hexagonal design and cantilevered concrete foundation appear to hover above the natural terrain. Massive European glass doors slide seamlessly into wall pockets, opening the living area to the outdoors. While the exterior boasts a dramatic silhouette, the interior is thoughtfully designed with rectangular living areas, prioritizing comfort and functionality. The home includes three bedrooms, an office, two full baths, and a dramatic great room surrounding a central glass courtyard, a serene focal point that brings natural light deep into the home. The detached garage, with aircraft hangar doors, serves as the command center for the property's infrastructure. Designed to be fully self-sufficient with its own solar energy system, spring-fed water supply and commercial generator. The vast acreage offers several potential building sites for expansion. This one-of-a-kind property is ideal for a discerning buyer seeking privacy, sustainability, and impeccable modern design.
