I used to have a shop where I did upholstery and it had floor-to ceiling shelves on three walls, and the other wall was glass. I had a 4' x 8' sheet of melamine-covered plywood perched across a couple of dressers as an island in one half of the room - counter height. It was the BEST space for EVERYTHING I ever thought about doing, and I could see EVERYTHING! I'd probably duplicate something like that if I could.
I'd also have super, super well-built filing cabinets (that looked like fine furniture) that would accommodate 12" paper - that seems to be the hardest thing to store and/or disguise! They would have to be lateral files, too...
Happy for no reason...
