"Excellent service and knowledge of my structural engineering request. Just what I was looking for.!"

"Excellent! Prior to the work Bob was prompt to respond to my emails. Bob showed up on time and was fully prepared. His work was thorough (paying attention to detail), consistent, and completed the work in a timely manner. In addition, Bob was courteous and helpful in answering any questions. I would hire Bob again in the future for needed work, as well as, I would recommend Bob to customers."

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"Robert responded quickly to my request. He provided me with the services I needed in a timely fashion. I would recommend Robert Cowles PE for your project."

"My Husband and I , had Dustin design our dream home that we were getting ready to build. Dustin was professional, very knowledgeable, and very easy to talk too. He made the drafting part a very easy and fun experience!! We would recommend him to any of our friends and family!!! We are excited to start our journey on our cabin with Dustin!!!!"

If you're looking for an architectural designer who brings more than textbook knowledge to the table, you're in the right place. With over 40 years in the construction industry—as a builder, designer, and business owner—I’ve developed a deep, hands-on understanding of how homes are truly built. Every project, challenge, and collaboration has shaped how I approach design today. That experience allows me to design residential projects that go beyond the blueprint, grounded in practical insight and a lifetime of lessons learned on the job.
