Lake Berryessa Custom Home

Located on a 95-acre parcel along the northwestern shore of Lake Berryessa, this weekend home beckons recreational activities with sweeping views from every angle. Up a half-mile driveway from Knoxville Road running along the lakeshore, this home is off the grid, not connected to municipal utilities, with a spring on the property providing fresh water, photovoltaic solar panels providing electricity. The weekend home’s systems include on-demand hot water and in floor radiant heating to help on days when the passive cooling might need assistance. The structure consists of four blocks arrayed around a central rhombus-shaped court to take advantage of 360 panoramic views of the nearby lake and surrounding mountains, while simultaneously focusing inward to a glass-walled diamond shaped courtyard at the house’s center. The panorama that wraps the house differs significantly on each side, enabling the perception and experience of a place that changes dramatically as one moves throughout the space. The house and freestanding garage are situated atop one of a series of meadows surrounded by Oak, Pine and Manzanita covered hills. Totaling 2,300sf, the home includes a living area, dining and kitchen space, master bedroom, kid’s bedroom, and yoga room. The design engages spatial dynamics through experiential activation of negative space relative to conditions of surface, material, view and landscape.
