I converted our 20 x 20 Garage into a workshop and also added a 12 x 8 storage room right off the back door. As far as storage goes I use cabinets, drawers, peg board, . for storing tools and nick nats as well as my 4x8 workbench which has 12 drawers and the storage room houses my plywood and moulding as well as electrical, plumbing, and paint, just take a look at my woodworking site That should give you a few ideas. . I tell yah never enough room especialy when your in Home Improvement where every day your doing something different so you can emgine how much storage you need. There are a number of systems for the shop for storing and if you google it you will have more to look at than you can possibly emagine. As far as comressores go in the shop I have a 2hp dual tank (small one)and does everthing I need it to. I have opted not to paint the floor with any kind of colour but clear. Helps when your sweeping up but doesn't chip off like paint (or so you'd notice).
