Architecture changes people.

Rooted in nature, it shelters us, and inspires wonder,

transcending simple human need.

Striving for perfection in the details,

at every scale.

Seattle Architect 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 based in Seattle, Washington, providing professional design services for commercial, civic, residential, and healthcare projects throughout the Pacific Northwest and beyond. These services include architecture, programming and planning, interior design, feasibility studies, and sustainable design.

The Coates Design team, led by Owner and Architect Matthew Coates, AIA, is a group of dedicated Seattle architects committed to creating a positive and lasting impact through thoughtful design. Our team believes that architecture, when executed with care and creativity, builds community and strengthens the social fabric that connects us all.

We are inspired by the idea that architecture should respond to its environment – shaped by context, climate, and culture. Our mission is to design responsible, forward-thinking spaces that enhance the quality of life and foster meaningful engagement with the world around us. This philosophy drives every project we take on and defines who we are as leading Seattle architects.

      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.
