This Hillsborough iconic landmark, seen from highway 280, is on the market for the first time in 20 years. In 1976 Bay Area architect William Nicholson designed the multiple domed home that is nestled into the hillside overlooking Crystal Springs Reservoir. Architect, Eugene Tsui, designed the biologic kitchen. Interesting rooms include a game room, the conversation pit, and the 3rd bedroom with a loft. This is an amazing opportunity for buyers who appreciate the architecture and design. Great event home.
