Okay, let’s tackle this. So Charles has 36 years of experience as an architect and owner, which is a significant amount of time. He has expertise in multiple areas like renovation, sustainable design, and architectural design. Location is Nantucket, MA, which is a high-end market. According to the Bureau of Labor Statistics, architects in the Northeast region (which includes MA) have a median annual salary of around $80,000. However, with his level of experience and expertise, he might be able to charge higher rates. Considering his role as an owner and his skills, I would estimate his hourly rate to be around $125, which is slightly lower than the national average for architects but still competitive given his experience and location.
