'A collective approach to design and fabrication'

One Hat One Hand is a local production company that has become one of San Francisco’s finest design and fabrication shops, providing scenic designs for Bay Area ad agencies, feature films, large and small scale events, and custom interiors.

We began as a custom fabrication shop with a lot of folks from event production backgrounds, and the discipline and attention to detail learned in production design translated incredibly well to creating high-end sets, props, and installations. We expanded to include full service metal fabrication, prototyping, carpentry and woodworking, as well as design services like 3D modelling. From exhibit designs and trade show booths to full-service interior design and custom furniture, One Hat One Hand is a truly one stop shop for all your creative production needs. Ready to get started? Let us know! We can bring your ideas to life.


One Hat One Hand’s 25,000 square foot shop is equipped with a wood shop, metal shop, paint shop with spray booth, CNC router facility, outdoor yard for large projects and a day light studio for a variety of functions.

The tree house design offices perch high above the shop. Up here is where the magic begins. Working in Rhino, CAD and SketchUp our designers imagine, sketch model and render.

All of this together allows them the ability to take on multiple projects at one time.
