Very nice, I wish my 12x24 shop ( which is like yours in build ) was that organized also. I have been reorganizing it for the last few months after I picked up a very large glass bead/sandblast cabinet. Mine also serves triple duty as a bicycle shop a motorcycle shop and a power equipment repair shop so trying to find a place for everything ( and remembering where it is ) can be frustrating to say the least. I really like your parts bins looks nice and easy to find stuff and professional looking to boot( I use parts boxes made from cardboard ) Is your shop going to be heated and if so what type of heater are you going to use.
