The Sunridge Earthship is a residence designed by Michael Reynolds in his “Earthship Biotecture” style. It was designed for the actor Dennis Weaver and his wife, who wanted their house to demonstrate environmentally friendly living. The walls are made of three thousand recycled tires packed with dirt and covered with adobe. The interior is temperature-controlled by strategically placed windows, and by the tires, which are so heavy that they absorb the outside heat. In keeping with Reynolds’ theme of sustainability, some of the windows allow for food to be grown indoors—even in winter. Dennis Weaver and his wife were very happy with the residence, which continues to attract the admiration of bloggers and journalists.
