Sustainable Architecture

Built from the earth, built to last.

The most sustainable buildings ever made were built before synthetic materials existed. We apply those same lessons today.

Sustainable Architecture

Sustainable doesn't mean synthetic.

The most durable, least toxic, most environmentally honest buildings ever constructed were built before synthetic materials existed. Timber, lime, clay, hemp, straw, and wool — these are the materials that have housed humanity for millennia, and they remain the best answer to a building that should last, breathe, and return cleanly to the earth at the end of its life.

Our sustainable practice is not defined by certifications or points systems, though our buildings typically meet or exceed those standards. It is defined by a commitment to materials that are honest: grown from the earth, permeable to moisture, free of petrochemicals, and capable of aging gracefully.

What We Use

Traditional materials with centuries of evidence.

Linseed oil paint — Penetrates rather than films; has protected timber, masonry, and metal for centuries. Original applications on 500-year-old Scandinavian structures remain intact.

Lime plaster and hempcrete — Hygroscopic wall systems that absorb excess humidity and release it, actively regulating the interior environment.

Straw and wool insulation — Biogenic, deeply permeable, and excellent thermal performers that regulate moisture rather than simply resisting it.

Locally sourced and reclaimed timber — Old-growth timber with tight grain and intact natural resins outlasts any laminated substitute.

Questions

About sustainable and biogenic construction.

Are biogenic materials more expensive than conventional ones?

Some are, some are not — and the relevant comparison is lifecycle cost, not upfront cost. Linseed paint lasts significantly longer than acrylic and requires no stripping before reapplication. A breathable wall assembly that lasts 200 years without replacement costs far less than a sealed assembly that fails in 30. We help clients make these comparisons honestly.

Do you build to Passive House standard?

We design for very low energy use and share Passive House's emphasis on thermal performance. However, we do not use the closed, sealed assemblies that standard Passive House certification requires, as these are incompatible with a breathable building strategy. Our buildings typically perform comparably in energy use with significantly lower material toxicity and better long-term durability.

Can I get a healthy home without a large budget?

Yes. The most powerful tool we have is efficiency of plan. A smaller, well-designed house with honest materials costs less to build and maintain than a larger one with conventional materials. We believe in this deeply and design accordingly.
