Highly recommend. **★★★★★ — Dane Lovejoy, May 2018** > Currently engaged with Studio Prime in support of a design/build project here in the city of San Luis Obispo. I couldn't ask for a more knowledgeable and professional group to work with, but importantly, they also have a sense of humor (especially John). They are helping my wife and I design (and eventually build) a 3,000 sf custom home on an, um, "interesting" hilly site that is presenting some challenges. However, these guys know their stuff, and are deftly navigating us around those challenges. Strongly recommend these guys! ## Selected projects - [California Cottage Estate](https://www.houzz.com/hznb/projects/california-cottage-estate-pj-vj~7643208) - Location: Nipomo, CA - Photos: 6 - Description: This project entails the design of a luxurious 9,000+ square foot single-family residence set amidst the vineyards of Tiffany Ranch, just outside San Luis Obispo, California.
