Help Me Plan Out the New & Improved Shop

I think of things like insulation and ways of heating and cooling the shop so no matter the weather you can work comfortably, what about a dehumidfier to help with moisture control. I know with powder coating that can cause problems. We keep the operating rooms around 50-60 % it helps with static electricity control and well as bacterial growth. Painted floors for easier clean up, maybe an office with a desk, dry erase board to keep track of customers jobs, and a computer.
