Coates Design is a 14-person architectural firm located on Bainbridge Island near Seattle, Washington. The firm provides professional design services for commercial, civic, residential and healthcare projects throughout the United States. Services include architecture, programming and planning, interior design, feasibility studies and sustainable design.
The firm’s managing partner, Matthew Coates, achieved international acclaim by winning the “Cradle to Cradle (C2C)” Home Design Competition in 2005. He captured the momentum from this accomplishment to create a firm dedicated to “Responsible Architecture.” The core values of the firm are based on simple principles and strategies: do the right thing, take the long-term view and create designs that benefit the environment, the economy and the community.
Team members with backgrounds in design, construction and the fine arts work together to transform complex design challenges into elegant solutions. The firm works hand-in-hand with our clients to ensure their goals, desires and specifications are met. Our clients have extremely high design standards, and we’re constantly evolving, refining and improving our work process to meet and exceed those expectations.
Coates Design Architects strives to address the reality that people spend 80% of their lives indoors by contributing buildings and spaces to our communities that are provocative, healthful and inspiring. We approach every project as an opportunity to design something unique that reflects the needs and goals of the individual client and creates a meaningful sense of place.
Our team seeks to reveal creative design strategies and technical innovation inspired by our clients, the site and the ecological context. We are collaborative by nature and we involve our customers early and often in the creative process. Our work reflects clean and elegant forms, well-proportioned spaces and natural daylighting combined with a “livable” touch which many designers overlook. We tailor innovative and livable design solutions through a customized approach for each and every client.
We believe that better design leads to better living. We seek to create buildings that not only do no harm– but also have a positive impact on the environment and the people who use them.
