11 Glorious Rammed Earth Homes That Celebrate the Landscape
A true expression of the landscape they rest on, rammed earth homes are constructed of compacted soil molded in plywood forms. A robust and energy-efficient material, rammed earth also has a striking, striated appearance, taking on natural color variations. The residences below demonstrate how the impressive building technique has been adapted to environments all over the world.

"We originally proposed using concrete for the walls because we like the plain style and directness," the owners say. Instead of concrete, Smith suggested rammed earth, a material that combines some of the physical properties of concrete, but is less "psychologically cold." The 16-inch-thick walls' thermal mass helps to insulate the interior from heat in the summer and cold in the winter.
"A well-performing house extension facing south on a small inner-city block built in rammed earth is not easy to achieve," says architect Steffen Welsch. "However, in this challenge was our opportunity: We decided that our extension will curl around to capture the sun, creating a communal courtyard and allowing the occupants to look at their own house rather than a paling fence."
Set in a valley in Wanaka, New Zealand, the home of winemaker Nigel Greening was conceived as a series of "tubes" that disappear at one end into the sloped landscape. Architect Andrew Simpson of WireDog Architecture worked with Dunlop Builders to create the 3,390-square-foot house, which features rammed earth walls both inside and out, a reflection of the owner’s connection to the soil. The kitchen features a mix of rammed earth walls, strandboard-and-bamboo cabinets, and stainless-steel counters. The appliances are by Fisher & Paykel, the faucet is by Plumbline, and the pendants are by Bruck.
