Planning a shop build, any suggestions?

I converted a small area in a pole barn that we once used when we farmed. The rafters were 18' high up, which means another story to toy with. This short movie I made while using some freeware that came with the computer, but then expired before I could finish. Nothing was drawn out and my carpenter friend was very good with "on the fly" suggestions. I enjoyed entertaining just as much as garage work and the two went will together. This shop is miles from my house, so I did make it comfortable to be a mancave/ garage.
