Sherry Williamson AIA, IIDA is a classically trained architect and specializes in residential interior architecture and design, custom furniture and lighting. After working for distinguished firms on both coasts, she established her interior design studio in Mill Valley, California in 1994. Custom light fixture design is integral to her work and adds a level of refinement and continuity to her projects.  

Recent projects include two LEED Platinum residences, and range from The Sea Ranch, Sonoma, Napa, Mill Valley, San Francisco, Kensington, Piedmont, Woodside, Portola Valley, to Carmel, CA as well as a family compound on the East Coast.  

Each residence reflects unique qualities of the owners in a relaxed and elegant style. Architectural proportions and simplicity are central to each design.

She has collaborated with Brayton Hughes Design Studios (BHD Studios) in San Francisco and designs lighting for Boyd Lighting, an internationally renowned lighting manufacturer. Past projects include hospitality, institutional and commercial interiors.  

Williamson holds a Master of Architecture degree from Yale University and a Bachelor of Arts in Architecture and French from Washington University in St. Louis. She studied architectural design and printmaking at the Ecole d'Architecture in Strasbourg, France, has taken an etching workshop at Crown Point Press in San Francisco, and enjoys printmaking and woodworking. She finds design inspiration through her passion for nature and art, including plein air drawing, watercolors, sculpture and ceramics.
