Core materials

Three materials, chosen with intent

Each material is sourced regionally and selected for its structural role, thermal behavior, and how it returns to the earth.

Structure

Structural timber

Regionally sourced timber forms the frame, giving each building a load-bearing skeleton that is workable, repairable, and grounded in local forestry.

Mass

Stabilized rammed earth

Compacted local soil, stabilized with a minimal natural binder, creates thick walls that store heat and buffer temperature swings through the seasons.

Finish

Breathable lime plasters

Natural lime plasters manage moisture and protect the walls without sealing them, keeping the envelope vapor-permeable and free of synthetic coatings.

Passive performance

Thermal mass and natural air exchange

Passive solar geometry orients each structure to the seasonal sun, minimizing energy demand. Thick earthen walls absorb daytime warmth and release it slowly through the night.

Vapor-permeable wall systems let moisture move through the envelope, supporting healthy indoor air without synthetic chemical barriers. The details shift with each site and climate.
