Hi Harvey

Acouple of ideas that you may consider in the design of “Your Ideal” shop are as follows.

Large storage boxes with lids and wheels faced to resemble drawers, in my opinion are better than cupboards under a bench because you get to use all of the space available, and the lids help keep out the dust. The wheels also permit a more thorough cleaning of the box/drawer itself and the area where it is parked when the mood strikes.

Electrical outlets in the ceiling above the work bench and stationary power tools helps control cord clutter. Ever notice for example that your shop Vac will not run over its cord, a ceiling mounted outlet solves this little aggravation. If your shop has a high ceiling, custom make some extensions that hang just above head height. You will be surprised a just how handy these are.

One mistake (in my view) a lot of fellows make is too large a work bench.
Make your bench just big enough to accommodate what you plan build.
“Big bench = Big clutter” The more flat surfaces you have the less room you ultimately have to work in.
Where to go BIG is on STORAGE…. The more “away” you have the better.
Put stuff away when you are done using it and you will be surprise how much less room you truly need.
