And indeed there was, like this rotating dome house. Solalaya, the American distributor of the Domespace home, like the one owned by the Vencat family, says, "Our planet rotates, why not your home?" One can probably think of a few good reasons right off the top, but there are also some real advantages, notably that it can follow the sun (or turn away from it.) The owner explains in Metro Green: "In winter, most of the windows can be facing the sun," says Shiva. "And in summer, the part where there are less windows will face the sun. Or you can program by computer to follow the sun; it turns very slowly." The passive solar is unbelievable, he says, and in winter it's a very efficient house. TreeHugger has shown a few rotating houses before: Solaleya Makes Weird Houses Feel Normal Our Jaymi wants one: "I have to admit I totally wanted to live in one by the time I finished listening in about their designs at their booth on the tradeshow floor." Rotating Shed Follows the Sun Team Spain proposed a rotator for its Solar Decathon entry this year. (well, actually only the roof rotated, which isn't quite so much fun). If you build small enough, you don't even need a motor; Susanne Watzeck & Jörg Sturm designed this shed that "may be rotated depending on the sunlight and desired orientation to enable both- climatic conditions." 1935: Villa Girasole: Rotating House Follows the Sun My favourite is always the Villa Girasole. "A revolving house is challenge to gravity, weitght and statics and to the very idea of rootedness." Rotating House by François Massau is 50 Years Old 50 years ago François Massau built this rotating house so that his sickly wife could enjoy sunshine and warmth any time of the year. Everingham Rotating House: Thinking Outside the Square In Australia, the Everingham House rotates around a central pivot point. "It also encapsulates many aspects of ecologically sound building principles, such as optimising on natural light and heat, while rotating 180o to take advantage of sunshine and shade at different times of the day and year." Rolf Disch's Heliotrop House And then, there is Rolf Fisch, architect of Vauban and so many other projects we love. He "built his own home as a test bed for solar systems. The house tracks the sun, so that its triple-glazed front can face the warming sun in winter and show its well insulated back in summer."
