Okay, let’s tackle this. So Gisselle has a solid skill set in interior design, including space planning and rendering. She’s based in Miami, which is a hub for design professionals. According to national averages, interior designers in the US can charge between $50–$100 per hour. However, considering her specialization in sustainable design, which is a growing field, and her experience with Revit, I’ll estimate her rate on the higher end of the scale. Maybe around $75 per hour, which is slightly above the national average for an interior designer with similar skills and experience.
