Okay, let’s tackle this. So Larry Gabriel has 41 years of experience as an architect, which is extremely valuable. His expertise in sustainable design, renovation, and construction is in high demand. He owns his own practice, which suggests he has a strong business acumen. Location is San Luis Obispo, CA, which is a relatively small market. However, his experience and expertise should translate to a decent hourly rate. Considering the skills and experience, I’d estimate around $200 per hour, which is on the higher end for an architect. This is because his experience and expertise in sustainable design are particularly valuable, and he owns his own practice, which suggests he has a strong client base and can command a premium rate.
