Many people commented on the North Napa seed library annex and asked, “How was it built?” Jeff explained how he put it all together.

“The seed library was built around a repurposed bathroom cabinet. The particleboard cabinet was not weather-resistant so the project simply involved constructing a weatherproof shell around the cabinet—essentially a “jacket” and a “hat.” Finally, it was mounted on two 4x4 posts at the build site near the sidewalk for easy public access.”
