Rad Rammed Earth
11645 Alder Hill Rd, Truckee CA (below)
For sale: $2,750,000
Although building a home out of rammed earth is a recognized green practice, it's by no means new. Homes with thick, earthen walls have dated back thousands of years and are long recognized as a sustainable and energy-efficient way to construct a home. Despite the more ancient technique of construction, this Truckee home for sale is by no means outdated. The house features a gourmet kitchen, geo-thermal fired heating system, as well as a planted roof and lawn with a robot mower.
