Earth Works: SIREWALL

B.C.-based Meror Krayenhoff has surely been warned about building castles in the sky. Sandcastles, to be precise. In the 1990s, he began experimenting with an ancient building technique called rammed earth, in which a moistened blend of sand, gravel and clay is compacted and formed into walls. His goal was to adapt this technique for the Canadian climate and modernize it to create homes that were healthier and more sustainable. The result of his efforts was SIREWALL—for Stabilized, Insulated Rammed Earth. Dozens of sustainable homes and commercial buildings around the world have since been built using SIREWALL.

Nk’Mip Desert Cultural Centre (pictured), in Osoyoos, B.C., is the first commercial building in the world to use the SIREWALL technique.
