Planning a shop build, any suggestions?

Original plan was a 40x60, then thought I might step it down to a 30x40, then decided to go the right thing and go back to a 40x60 plus a lean-to on one of the sides for a “barn area”
I believe you will be much happier with 40 x 60. Mine is only 24 x 28 and there are times I cannot even turn around good. I'm thankful for it, don't get me wrong. I know many people don't have anything, but dammit, I could have gone twice that when I did it and I didn't. Maybe one day.
