San Francisco Bay Area Interior Design

Isolina Mallon Interiors is a full-service interior design studio creating refined, architectural homes throughout the San Francisco Bay Area.

Rooted in a contemporary European sensibility, our work balances warmth, functionality, and thoughtful restraint to create homes that feel timeless, cohesive, and deeply considered.

We specialize in renovations, custom homes, and large-scale furnishing projects, collaborating closely with homeowners, architects, and builders from concept through completion, guiding every phase of the process from spatial planning and lighting design to material selection, procurement, and final installation.
