Okay, let’s tackle this. So Kenneth Kistler has 44 years of experience as an owner of an architecture firm, which is a significant amount of time. His skills in renovation, sustainable design, and space planning are in demand. Location is Pittsburgh, PA, which is a mid-sized city with a relatively stable economy. Architecture professionals with his level of experience typically charge higher rates, but not as high as those in top-tier cities like New York or San Francisco. Considering his expertise and location, I estimate his hourly rate to be around $125, which is on the higher end of the scale for a regional architecture professional.
