When I built my shop, we used four 8’ benches, down one wall. Added a shelf that runs end to and, above all the benches. The first one is used for 8-12 small tackle boxes (on sale, $1.00/each). These hold items like hose clamps, zip ties, Allen keys, glues and sealants, etc. When I was racing every weekend, they came down, into a milk crate, and into the trailer, every Thursday night....
The rest of the shelves hold used windshield washer and antifreeze plastic jugs. Slice off one side and they make great tubs. The larger ones are great for extra storage. For each bench, the shelves hold up a 4’ light, nice and close to the work area.
