Okay, let’s tackle this. So Robert A. Richard Aia has 40 years of experience as an architect, which is a significant amount of time. His skills in residential design, renovation, and space planning are in high demand. He’s also got a degree from the University of Florida, which is a reputable architecture program. Location is Miami, Florida, which is a competitive market for architects. Considering his experience, skills, and education, I’d estimate his hourly rate to be around $250. This falls within the range of what other experienced architects in the Miami area might charge, especially those with a strong focus on residential design and green building.
