Planning a shop build, any suggestions?

There’s been a lot of excellent ideas shared here! I believe I’m going to change the build site of the shop to the opposite (south east) side of the house than I’d planned to, due to the amount of dirt work it would have taken on the northwest side of the house. Along with the new location, will likely also come a change in design. Instead of having the overhead doors in the eave side of the shop, I’m thinking of putting them in the gable end, then adding 12x60 lean-to’s down both sides of the shop.
One end of the shop will definitely have a mezzanine for parts storage, with a bathroom underneath.
