Earthship. The concept of an 'earthship' was developed by American architect, Michael Reynolds. Most are single aspect with glazing to the south & a north rammed earth filled tyre retaining wall. He built two for actors Dennis Weaver & Keith Carradine. The Weaver house in Ridgeway, Colorado came up for sale in 2004, hence many images. They generally feature recycled materials & self-sufficiency in energy & water.
