rammed earth

Packed dirt construction

Rammed earth is a building technique where moist soil is compacted into forms to create dense, sturdy walls.

The method dates back thousands of years and remains valued for its durability, thermal mass, and low environmental impact.

The rammed earth walls kept the house cool in summer and warm in winter.
