I agree about having to need 2 areas, I pad in a bit more space, like a 7x7 area and that barely allows for room around the hot tub in the comfort zone. I keep the workbenches in a circular area with additional living quarters above on stilts/pine log. Comfort outside in the work area is much lower and I could raise it with more render clutter, but I keep it lower as it's just a step inside to zip back up to full comfort...
