Before you reach out
- Clay sourcing for cob is often its own project — not every site has workable clay. Cob section →
- Timelines follow the material, not the calendar. Drying and curing can't be rushed. Build phases →
- Gathering materials ahead of a build — clay, sand, straw — makes everything smoother. Materials sourcing →
- We prioritize projects where quality clay is on site or the client is ready to source it.
- Permits depend on what you're building, where, and how it's classified. Worth understanding early. Permits & codes →

→ [email protected]A note on cob and clay
Cob requires good clay soil — and while Portland is known for it, finding a workable source isn’t always straightforward. Not every site has usable clay on it, and we don’t have a standing supplier we can order from. Clay sourcing is often its own project, and it’s one of the real reasons we’re selective about what we take on. Priority goes to projects where quality clay is already on site, or where the client is prepared to source and deliver it. If you’re thinking about a cob house or a larger cob structure specifically, this is one of the first things we’ll want to talk about.
