Planning a shop build, any suggestions?

Exterior design has been decided (barring it costing way too much). Main shop will be a 40x60x16 with a 6/12 pitch roof and a 14x60 3/12 lean-to running down both sides. Doors will be 12x12’s in the main shop, and 10’ wide by however tall I can go in the lean-to’s. Plan is to use metal wainscot on the bottom 3’ or so, then do poplar board and batten from there up. Also plan to install windows under the eaves of the main shop for added natural lighting.
