SFist commenter jacksevanroo's facetious reference to buying a geodesic dome in response to Larry Ellison's questionable tax break on his "functionally obsolete" compound, reminded us about this Silicon Valley geodesic dome home ("Brigadome") that went up for sale last month. If we could buy it, we would -- hippie stigma be damned! (Buckminster Fuller was the most under-rated genius of the 20th century, as far as we're concerned.)

Located in the San Francisco peninsula foothills in the heart of Silicon Valley, this 20-year-old dome in a country/urban setting has three bedrooms, two baths, cathedral living room, front and back decks, and a two-car garage in a large basement including a wine storage room. Walk-in closet, custom vanity, mezzanine office area, and built-in vacuum; custom solid white oak cabinets throughout. Two-by-six construction with R30 insulation saves energy costs. Five extensions (kitchen is 12-footer) lead to 2000 sq ft of living space. Stairway from back yard brings you to master bedroom in loft. All this just 25 minutes from San Francisco, San Jose, and Pacific Ocean Beaches. Request more information at 650 364 3663 or fogdome@sbcglobal.net. $1,295,000 (houses on either side valued at $2M – location, location, location).

There's an even bigger dome for sale in Livermore that's going for $1,119,000. It's 3400+ square feet, with four bedrooms, a gourmet kitchen, large living room, family room, sun room, formal dining room, and a studio retreat. The property is located on five acres with its own Petite Syrah vineyard!

Two even more affordable domes are for sale near Santa Cruz and way up in Taylorsville.
