We needed a site plan, fairly quickly, in order to receive permits on a small roof repair. > We had plans and subsequently a permit within a week :-) **★★★★★ — Kim M, Aug. 2024** > Erin is such a pleasure to work with, she was able to take our ideas for our pool house and translate them onto paper.

All around, we would definitely go with Erin LeMaster Architecture + Design again with any project needs. ## Selected projects - [Sapele](https://www.houzz.com/hznb/projects/sapele-pj-vj~7425104) - Location: Santa Ana, CA - Photos: 8 - Description: This project consisted of a complete systems upgrade and public space remodel of a 1970s ranch style house in North Tustin, CA.
