The building looks good so far. You do have some wall space between windows. The fun starts when planning on how to use it.
I hear you on the wall space.
Today they installed the new garage door and I was shocked how that simple change made the shop appear smaller. Our contractor said, "Wait until they put the windows in tomorrow.". Great! The shrinking shop. Just what I wanted. When all the tools arrive, I may have room for my coffee cup. Ha!
I've been waiting for this shop for ten years and cannot wait for all of my tools to take up residence. No doubt wall space will be at a premium, but we'll manage as best we can.
