Valentina Leoni Architecture is a San Francisco based design studio founded in 2024. We work across residential, retail, and other types of commercial architecture, with additional experience in cultural and community projects.

Our range of work spans traditional architecture, interior architecture, furniture design, and mosaic, stemming from a broad interest in materiality and craft. With a background in architectural finish fabrication and belief that good buildings are conceived in the dialogue between drawing and building, we emphasize early collaboration with builders, cultivating ongoing partnerships with them throughout the design and construction process.

We begin projects with careful listening and observation. We then respond to our clients’ goals and the unique context of each site through a design process grounded in modeling, drawing, and material exploration. The result is thoughtful, enduring architecture that prioritizes well-being for both people and place.
