Tom Perilstein

I have worked with Matthew and his team at Coates design on two houses now and have enjoyed the process immensely . I felt as though I was part of the process on both projects and found Matthew to be very attentive and respectful to what my wife and I were looking for. He has an exceptional feel for what the site calls for and what the layout of the house should be to achieve it. The spaces are always full of light, open and airy, with a feeling of bringing the outdoors to the inside space which was our most important goal for each house. His attention to detail is great and his plans are thorough and well documented, minimizing any problems during construction. Having lived in our first house designed by him for 17 years to date and enjoying our second house for 5 years now, we can’t imagine living in a home designed by anyone else.

I hired Coates Design to help me design and build an elevator in my home. I was asked for a retainer, which I paid, and which was quickly spent by Coates Design. However, never once was I asked the kind of questions I might expect to be asked to design an elevator in my home. In addition, my job was assigned to someone whom I had not interviewed and seemed to have no knowledge of what I wanted or needed in my home. When I complained, I was told the money had been spent. As of now, I am out the large retainer fee, plus an additional invoice that I paid, and I have no work to show for it. We have parted ways, but I would be very careful when interviewing Coates Design Architecture to find out more than I did about their processes, communication, and spend structure. It was an incredibly disappointing experience and I cannot warn future clients away from this firm more strongly.

Clark Construction Inc.

Coates Design has been our partner on several projects, including a significant renovation of a medical facility into a police department and municipal court. Recycled construction materials from this project were then used in the design and construction of a tiny home community for farming interns. The reHome project diverted 2,6000 pounds of construction waste from the landfill and won the AIA 2022 Honor Award of Merit in research and innovation. Coates Design demonstrates a strong commitment to sustainable building practices, which is a guiding principle at Clark Construction. They integrate environmentally responsible strategies into the projects we've partnered on, considering factors such as energy efficiency, natural resource conservation, and the well-being of occupants. We appreciated how Coates worked alongside us throughout all phases of construction, valuing our expertise and engaging in thoughtful discussion when decisions needed to be made.

Matthew and his staff are highly-creative, and reliable. In the two years we've been working with them, they've helped us through one small project, as well as planning a full-house remodel. I've recommended them to friends.

Matthew and team always put the client first.

Matthew Coates & Associates are amazingly talented! I have worked with Matthew on two projects and also referred him to real estate clients. Matthew is a highly skilled problem solver with fabulous esthetics and a great communicator. Also, he has built a team of top notch Associates. Matthew designed the stunning BIMA (Bainbridge Island Museum of Art); a building for which we Islanders are very proud! I highly recommend the Matthew Coates Architectural Design firm.

Our experience with Matthew Coates and his team was excellent. Our shared goal was to create and maintain a dialogue, as well as to create a vision of aesthetic functionality and delight. Matthew and his associates made a genuine effort to listen; ask critical questions and exercise a conscientious sense of courtesy and integrity throughout the process.

Wonderful, creative design work coupled with great attention to detail in the plans and the execution of the building project.

Todd Cain

Matthew and his team are thorough, professional, creative and responsive. Building one of their projects becomes a cost effective endeavor for both the builder and the client. It's not enough to capture someone's idea on paper. It needs to relate to the client's budget and schedule as well. It also needs to be thorough and clear enough for the builder to take it from design to reality. Coates Design does a great job balancing the entire creative process.
