One Hat One Hand is a San Francisco-based specialty general contractor licensed in California. We’re known for our work in public art, architectural placemaking, workplace design, experiential installations, and product prototyping.

Our team of designers, fabricators, artists, welders, and technologists collaborates with artisans, architects, developers, every day to create large-scale placemaking features for events, public art, architectural millworks and architectural metal. We thrive on building projects that are large, complex, or have never been attempted before.
