Studio Sarah Willmer Architecture Studio Sarah Willmer Architecture is an award-winning nationally and internationally published architecture and interiors firm based in San Francisco. The primary premise of the studio is a strong belief that collaboration with the client creates a more dynamic and unique design solution for each project. The principles of simplicity, of spaciousness and light, of synthesis and function are realized in each project. Three principals guide the design process with each client: the building’s structure as a primary expression of space, the control and infusion of natural light, and an environmentally sensitive and elegant material palette. The creative energy at Studio Sarah Willmer is vitalized by the extensive experience of its senior staff and youthful enthusiasm of recent grads from University of California, Berkeley and California College of the Arts. The team is tight and selected for their unending commitment to quality architecture and critical design.
