Okay, let’s tackle this. So Gavin Mitton has 24 years of experience in the architecture and design industry, which is a significant amount of time. His skills include interior design, project management, and green building, which are all in demand. However, his role as a Director at Design 360 suggests a more senior position, but not necessarily a high-level executive role. Location is the City of Cape Town, Western Cape, South Africa, which may impact salary. Considering his experience and skills, I would estimate his hourly rate to be around $120, which is on the lower end of the spectrum for a Director-level professional in the architecture and design industry. This rate is likely influenced by the local market and industry standards in South Africa.
