### All 3 reviews

**★★★★★ — Daniel Hiscocks, Feb. 2019**

> We went with Gilliam Arch to design our ADU in Eagle Rock. Working with Jonathan has been great. He is professional but easy to work with. We felt he truly listened to us and designed exactly what we were looking for. His vast knowledge of the building industry and the process with the city has been so helpful and reassuring. Everything came in on time and on budget. We would definitely hire Jonathan again.

**★★★★★ — Red bench, Feb. 2019**

> One thing I was looking for in an architect is somebody that could actually understand what my vision was and put it down on paper. I explained to Jonathan what I wanted to see, and how I wanted the house to look like, he put that down and immediately understood my vision. I couldn’t have asked for a better architect. His involvement did not stop with him delivering my plans, He continued to be a resource throughout my construction and beyond.

**★★★★★ — Keith Hamilton, Feb. 2019**

> Thoughtful, creative, personal, and affordable.  Jonathan worked together with me to re-imagine my kitchen & bathroom and was an essential resource throughout the months-long renovation.  I cannot recommend him highly enough.
