Congratulations on starting your shop! I experienced somewhat the same thing when I built mine some years ago. I had a roughly 8x8' storage/tool shed that I had EVERYTHINHG crammed into, and I wanted something bigger. A good friend of mine suggested that I build something big enough to work on my car in, and so my plans mutated; what started out as a 24' x 24', finally came to be 24' x 32'. The small shed HAD to remain in place, until the new one was built. Unlike you, I had to cut a couple of trees and a lot of other 'issues' which make a long and entertaining story, but one TOO long to type out, LOL!! Suffice it to day, the glow of completion couldn't be beat, as a matter of fact, I had to see cars parked in it right away! Good luck on your project, and be sure to get a LARGE bottle of Alleve/Tylenol/Advil, or whatever pain reliever, 'cause you're gonna need it!!
