With its octagonal design that’s part Jetsons, part Bond, John Lautner’s Chemosphere House is considered a masterpiece of California Modernism. Perched on concrete poles, the home is reached via an inclined cable railway. Wiki link.
Lautner ingeniously solved the problem of the 45-degree slope by siting the entire house off the ground atop a 50-foot (15 m) concrete pillar that rests on a massive concrete pad 20 feet (6.1 m) in diameter and 3 feet (0.91 m) thick, buried into the rocky hillside. Halfway up the pillar, eight angled steel “spokes” — bolted onto bosses formed onto the surface of the column — splay out and up, supporting and stabilizing the outer rim of the house, and the center of the pillar also houses the utility cables and pipes.
Lautner provided access from the driveway up the steep hillside by installing a funicular, which terminates at a short sloping gangway that leads up to the entrance. The house is octagonal in plan and lozenge-shape in section, and is often described as a “flying saucer”.
