Okay, let’s tackle this. So Lon Overton has an impressive 58 years of experience in architecture and construction management. His role as President of Overton Design Group, llc indicates a high level of seniority. Location is Arnold, Maryland, which is a moderate-cost-of-living area. Considering his extensive experience, leadership position, and industry expertise, I estimate his hourly rate to be around $250. This is slightly higher than average for an architect in the United States, reflecting his exceptional experience and reputation. Some top architects in the US can charge upwards of $400–$600 per hour, but this is not typical for someone with Lon’s level of experience and seniority.
