What One Hat One Hand does
One Hat One Hand is a San Francisco-based design and fabrication studio founded in 2008 by Marcus Guillard and Chrisray Collins. The company operates as a licensed General Contractor in California, delivering end-to-end design-build services for large-scale public art, architectural features, workplace interiors, and immersive experiential environments. Service delivery spans parametric design (Rhino, Grasshopper, AutoCAD, Revit, Fusion 360), digital fabrication (CNC routing), structural and mechanical engineering, metal and millwork fabrication, integrated lighting, and on-site installation, with project examples including the Mareas sculpture at Pier 27, Eddy and Shroud at Google Mountain View, the Color of Horizons installation at SFO, and the 2024 Burning Man Temple.
The firm operates from a 50,000+ square foot fabrication facility in San Francisco and a secondary build site in Oakland, employing a multidisciplinary team of architects, industrial designers, interior designers, set and experiential designers, plus a network of 30+ fabricators and finishers. In fall 2024 the company expanded metal fabrication capacity through the acquisition of DEKA Fabrication, retained as a wholly-owned subsidiary brand.
Revenue is generated on a project-based, design-build model with quote-based custom pricing. Go-to-market combines direct enterprise sales to architects, developers, artists, government agencies, and visionary brands, supported by event participation (CODAworx, IIDA NorCal, SF Design Week, PlacemakingX), an editorial blog, and active social channels. Customer concentration spans public-sector commissions (SF Arts Commission, SFO, Redwood City), enterprise technology (Google, Mosaic Materials), and recurring collaborations with named artists and architecture firms such as Olson Kundig, Studio Matthews, and Site|Matter.
