Okay, let’s tackle this. So John Tankard has 48 years of experience as an architect, which is extremely rare and valuable. His location in Waban, MA, is also a plus, as it’s a affluent area with high demand for architectural services. His skills in architectural design, interior design, renovation, and architecture are in high demand. Considering his extensive experience, location, and skills, I would estimate his hourly rate to be around $200. This is slightly lower than the national average for architects in the US, but it’s still a competitive rate considering his level of expertise and experience.
