At Catherine Coy Design, we design quietly luxurious, highly functional spaces tailored to each client’s lifestyle. Working closely with master furniture makers, cabinet builders, contractors, and architects, we represent our clients’ best interests from concept through installation. Our practice is intentionally discreet—privacy and confidentiality are paramount—and we’re proud that for the past 15 years our work has been entirely referral-based, with many repeat clients. Materials are selected for quality and longevity, with a refined, nature-influenced palette that complements each home’s setting. The result is layered, enduring interiors where craftsmanship, comfort, and subtle elegance live in balance.

Based in Marin County, California, we are currently working on projects in Lake Tahoe, and throughout Marin County.
