September Studio is a full-service boutique interior design firm based in San Francisco.

Through a hands-on approach, we design fresh and timeless spaces to enrich the daily lives of our clientele.  The foundation of our aesthetic is clean and classic, blending modern minimalism with serene comfort. Every detail is carefully considered, thoughtfully selecting materials, finishes, textures, and subtle hues for a well-balanced and layered interior. 

We collaborate with skilled artisans, builders, and architects on small-scale design projects to large renovations. Our services are customized to meet any requirement from inspiration to final installation. 

We prioritize sourcing sustainable materials from eco-conscious companies. We support California based, local, and female owned businesses whenever possible.
