When San Francisco artist and builder Jay Nelson sees someone tearing down a redwood fence in his neighborhood he asks if he can take it home with him.

With a stockpile of salvaged, old growth redwood fencing, he recently built a tiny studio for his friend, and neighbor, Lana to use as a home office. It’s just under 100 square feet and that means it’s small enough so that San Francisco doesn’t require a permit.

In this video, Nelson shows us his stockpile of wood, the studio made of nearly all salvaged materials (doors, windows, flooring included) and how it nearly melts into the yard because of its rounded shape. He also gives us a peek at the greenhouse he’s building out of some of his recycled redwood just next to the studio (see his blog for more finished photos with decking).
