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, and builders to create large-scale placemaking features, art fabrication, and specialty installations. We thrive on building projects that are big, complicated, or have never been done before.
