My shop is a 600 square foot second story addition to my garage. It has a 9.5' vaulted ceiling, 2 4' x 4' North facing skylights, and a 10' wall of windows for plenty of light. To deal with the issue of getting large items up and down, I built in a 4' x 8' trap door in the floor. Above it runs a 9' I-beam attached to the ceiling from which I have trolley and winch. Open the door, pull it up, slide it over..perfect!
