The network

Three manufacturers making panels today, six more on the way

New Frameworks built the first straw panels in the country, then went looking for people to build them with. Rare Forms and Building Integrity picked it up, and the three of them founded the Collaborative together. A new cohort has joined every year since.

Seed Collaborative member manufacturers across the United States A map of the United States. Manufacturers active today are marked in Vermont, Massachusetts and Missouri. Manufacturers setting up are marked in Washington, Oregon, California, Colorado, Minnesota and Maryland. Field Assembly, also in the 2026 cohort, is searching for a shop site across Ohio, Rhode Island, and the western Catskills of New York, and is not shown on the map until a location is set.

The Seed Collaborative network A honeycomb with the Seed Collaborative at the centre. The inner ring holds New Frameworks, Building Integrity and Rare Forms, which are manufacturing today, together with the 2025 cohort: Earth-Bound Building with POM Studio, Living Craft, and A1 Design Build. The outer ring holds the 2026 cohort — BrightBale, Earth Light Build with Sol Design Build, and Field Assembly — with empty cells left for the manufacturers that join next.

Every manufacturer has a cell, including the pairs that joined the Seed Program together. Green is manufacturing today; blue joined in 2025 and amber in 2026, both setting up now. The dashed cells are held for whoever comes next.

Shared ground

What every manufacturer holds in common

Independent manufacturers, one set of terms. Whichever member makes your panels, they work to the same six commitments — and that is what makes this a network rather than a directory.

  • We refuse the trade-off between low carbon and high performance.
  • We build to the drawing, exactly.
  • We treat the trades as skilled work, and pay accordingly.
  • We buy from farms and mills close to the shop.
  • We teach the method, because it was taught to us.
  • What one manufacturer learns, every manufacturer gets.
What each one means

Regional specifics stay with each manufacturer. For pricing, lead times, and local availability, we’ll put you in touch with the manufacturer nearest your site.
