Cullinan Studio is a co-operative practice, founded on the principal that "the design of buildings is a social act". The studio's design philosophy is rooted in humane, ethical design.
The studio has been a leader in sustainable design for 60 years, and continues to engage in research and training toward circular economy principles of zero waste.
Cullinan Studio is expert in ecologically-conscious, healthy design, creating places that incorporate natural materials, and renewable energy sources, as well as daylight, fresh air, and green spaces.
Through evidence-based design, the studio consistently applies "lean thinking" to its work on both new build and existing buildings.
