Rammed Earth House, designed by Designs Northwest Architects, stands on farmland in Western Washington. Completed in 2025, the project responds to its pastoral context with a focus on energy efficiency and modern, sustainable construction techniques.
The residence employs exterior walls formed from earth and cement, compacted in lifts to create a layered appearance, with an 8-inch polyisocyanurate insulation core embedded within each wall. This assembly combines the visual qualities of stone with the energy performance benefits of a super-insulated envelope. The substantial thermal mass provided by the rammed earth construction helps to moderate interior temperatures, reducing energy demands throughout the year.
