Okay, let’s tackle this. So Terry Harrison has 53 years of experience as an architect and interior designer, which is extremely valuable. He has a strong educational background from the University of British Columbia. Location is Vancouver, BC, which is a hub for design and architecture. Considering his extensive experience, education, and location, I would estimate his hourly rate to be around $150. This is a conservative estimate, as experienced architects and designers in major cities like Vancouver can charge higher rates. However, without specific industry benchmarks or salary data, I'm taking a cautious approach.
