Okay, let’s tackle this. So Svein Juberg has 48 years of experience as an architect, which is extremely rare and valuable. His skills in architectural design, sustainable design, and interior design are in high demand. Location is Trondheim, Norway, which is a smaller market compared to major cities in the US or Europe. However, Norway is known for its high standard of living and emphasis on sustainability, which could command a premium. Considering his experience, skills, and location, I would estimate his hourly rate to be around $125, which is on the lower end of the scale for experienced architects in Norway. However, this is a rough estimate and may vary depending on the specific project requirements and client budget.
