Note: This is strictly a low budget build. I'd much rather have a bigger, nicer building, with hydraulic lifts, insulation, A/C, etc. So most will not be interested in this series at all. But, for the low budget guys that can handle a $10k budget build, some of this info may be helpful.
We chose Earth Brown roof/trim & pebble Beige wall panels.
Seeing the guy standing up walkin the iron reminded me of when I was an iron worker apprentice. It took a while to be able to walk it, standing up. It just felt a lot safer to get down an "coon it".
Ya'll might notice that the North doors are not centered. I did this so that I could put some 12"-15" shelves and work tables along the East wall, and still have room to work around a car parked inside the East door opening. Might be able to use slightly wider tables. Not sure yet.
