I was introduced to Daniel at Affinity Design Group through my general contractor and designer. Daniel prepared the architectural and structural plans and calculations for a room addition project at my home, which included expanding a second-floor bedroom and office space and enclosing an exterior courtyard to create a new foyer.
Daniel was very easy to work with throughout the entire process. He was responsive, professional, knowledgeable, and kept the project moving efficiently. The City had only very minor corrections to his plans, and Daniel addressed all of them in less than a week.
His pricing was fair, but what really stood out was the quality of his work and his responsiveness. I am extremely happy with the final outcome and would highly recommend Daniel and Affinity Design Group to anyone looking for professional architectural or structural design services.

I wanted to remodel my home's interior, including removing several interior walls and enclosing a patio to create additional living space. Affinity Design Group scheduled a virtual consultation, and Daniel showed me several similar completed projects. After seeing his work and discussing the project, I felt confident moving forward with him.
Daniel was great to work with throughout both the architectural and structural design process. He also introduced us to a general contractor to do the construction.
Daniel completed the plans and calculations quickly and submitted everything to the City. The plan check came back with only minor corrections, which he addressed within a couple of days.
I’m very happy with the outcome and would recommend Affinity Design Group to anyone looking for architectural and structural design services. Thanks again, Daniel and Affinity Design Group!

Daniel was incredibly helpful and took the time to answer my questions about some checking I noticed in a structural wood beam. I sent him a video and a few photos, and he carefully reviewed everything before providing a detailed explanation.
He explained why the checking wasn't a structural concern, what would make it more serious, and why it was most likely natural checking from the wood drying over time. His explanation was clear, easy to understand, and really put my mind at ease.
I really appreciate him taking the time to help me and would absolutely recommend Daniel and Affinity Design Group to anyone looking for honest, knowledgeable structural engineering advice.

Please don’t hesitate to reach out if you have any additional questions or need assistance in the future.
Thanks again!

We hired Daniel from Affinity Design Group for our detached ADU project and had a great experience from start to finish. He was extremely professional, responsive, and efficient throughout the entire process.
What really stood out was the speed of service. He turned around plans and revisions quickly, which helped keep our project moving forward without delays. His pricing was fair and transparent, and the quality of the work was excellent.
Daniel was also easy to communicate with and took the time to explain things clearly whenever we had questions. Overall, we were very happy with his services and would highly recommend him to anyone looking for a reliable and professional engineer and architect for an ADU project.

Daniel handled the plans, structural calculations, and coordination with the city for my room addition project, and the entire process went very smoothly. His plans were thorough and well thought out, which resulted in minimal corrections from the city—and the few that did come up were addressed quickly, often by the next business day. He was consistently responsive, professional, and easy to work with throughout the project. His knowledge and attention to detail really showed, and it made a big difference in getting our permit approved efficiently. I couldn’t be happier with the outcome and would highly recommend him to anyone looking for quality design and engineering services.
