I’m looking for motivated volunteers to join a participatory building project in beautiful rural Brittany!

If you’re interested in bioclimatic design, natural building, or simply want to learn by doing, this is the place for you. Whether you’re available for a few days or several months, you’ll be warmly welcomed.

The construction starts in April 2026 and will last... well, as long as it takes.

Keywords: bioclimatic architecture, timber frame, straw bale, earth plaster, natural building, rainwater harvesting, permaculture, self-build.

🌿 About the "QG" Project

I’m building an eco-friendly house using:

• Double timber frame structure with straw bale infill (GREB method)

• Earthen and clay–straw interior plasters, and lime plastering on the outside

• Rainwater harvesting and natural wastewater treatment (phyto or soil-based system)

The house sits on a one-hectare plot (2.5 acre) of former farmland, surrounded by countryside.
Future plans include two small eco-studios (straw or earth construction), a forest garden, ponds, and a mini-forest.
