The Largest and Most Diverse Fabrication Capabilities and Services in the Bay Area

At One Hat One Hand, we don’t just fabricate — we elevate. As a leading name in public art and a trusted fabrication partner, we offer one of the most extensive and comprehensive ranges of capabilities in the Bay Area. From public art and sculpture to workplace and interior design, architectural millwork, and immersive experiential environments, we unite every facet of craftsmanship and innovation in one shop.

Our multidisciplinary team of designers, fabricators, artists, and technologists collaborates seamlessly with architects, developers, and visionary brands. From initial concept through meticulous installation, we masterfully deliver custom design, scenic fabrication, precision lighting, and architectural metals — transforming bold visions into enduring landmarks.
 

Complex, daring, boundary-pushing projects? That’s our playground. If it needs to be bold, custom, or seemingly impossible, One Hat One Hand is your trusted partner to make it happen. When you want the largest, most versatile fabrication expertise in the Bay Area, you want us.

We're excited by new technologies that help us imagine and visualize our work and the tools that help us stay on track, communicate with our clients and deliver beautiful results. What's the 'secret sauce?' Creative Director and Co-Founder Marcus Guillard shares the secrets of One Hat One Hand.
