About the Firm
Ann Maria Celona, Custom Homes and Workplaces is a full-service design firm based in the San Francisco Bay Area and specializing in fine residential projects. Since 1985, we’ve brought our personalized design approach to a wide variety of projects, working closely with clients to create spaces that make their daily living and working routines more enjoyable and satisfying.

Our services include the design of interior and exterior remodels and additions, new custom homes and Bay-Friendly landscapes. We offer particular expertise in historically sensitive renovation, emphasizing continuity with historical elements while creating new spaces that work for contemporary needs.

We help clients navigate the design process from conception to completion. We understand the increasingly complex web of local regulations governing construction and tailor our projects for a smooth approval process.

Our attention to detail during design and construction has helped us forge lasting bonds with experienced local builders and craftspeople. This continuing relationship informs our design work and results in projects finely tuned to our clients needs and budget.

About Ann Maria
"I am interested in the long view, the sequence of spaces that borrow from each other, enlarging and enriching the experience of the whole. My work with clients is an extended conversation in which together we imagine and craft the view."

Ann Maria Celona holds a Master of Architecture degree from the University of California, Berkeley and a Bachelor of Arts degree in language and literature from Oberlin College.
