transcending simple human need.

Striving for perfection in the details,

at every scale.

Seattle Architects Coates Design specializes in sustainable design and green building techniques. Unique among other Seattle Architects is our ability to solve complex design problems with a customized, client-focused design process that is both efficient and highly rewarding.

Our architectural design firm is located on Bainbridge Island near Seattle, Washington, providing professional design services for commercial, civic, residential and healthcare projects all over the State of Washington, as well as California, Oregon, Idaho, and beyond. These services include architecture, programming and planning, interior design, feasibility studies and sustainable design. The Coates Design team is inspired by Owner and Architect Matthew Coates AIA, who has built a firm that is committed to creating a positive impact. As a local Seattle Architect, Coates has carefully assembled a creative and experienced team that shares a deep belief that architecture, when executed thoughtfully, builds community and contributes to the fiber that elevates and holds society together. We believe that architecture itself is often shaped by its biological and inherent relationship to its environment. Our desire is to create and advocate for responsible architecture; architecture that advances the quality of our world, and our ability to meaningfully engage with it. This is the driving force and inspiration behind our work.

      The core values of the firm are based on simple principles and strategies:

      Do the right thing.

      Take the long-term view.

      Create designs that benefit the environment, the economy and the community.
