Here's a few things that make my shop functional:
Shelves for frequently used items - I like all my stuff visible, not hidden in cabinets. It all gets dusty, but I can usually find stuff fast.
Shelves mounted very sturdily - some of those red bins weigh 30#. There are many more now.
Outlets located just under the shelves - above the clutter of the workbenches. If I was to build a shop I'd put a double duplex every 32" in this area. Note how the power strip is tipped so outlets are pointing down - the dust in my shop has a high metal content, and is conductive. Blow out the outlets once in a while, before they make sparks.
Lighting - under lower shelf is now a dual 4' T8. Overhead is 3 continuous rows of dual 4' T8 fixtures = 34 bulbs serving approx 950sf. It's just about right. Higher ceiling would need more.
This area has a loft overhead for storage, ceiling is under 8' with beams lower than that. A full 8' clear all over would be better. If you can recess the sprinker heads, do it. When I'm handling lengths of steel I'm constantly reminding myself of the sprinklers - really don't want to knock one of the heads off.
Loft has 6' clear to bottoms of main beams, ceiling is about 16'. 18' would be better.
Cushioned runner on floor - saves wear on feet
Hand me down kitchen oven is useful for preheating stuff, curing paint, etc. Pizza tastes funny, tho.
Utility sink, parts washer, cabinet for lubes/paints/resins. The yellow next to the white cabinet is a fire cabinet, mostly for waste fluids, and solvents.
Overhead exhaust vent to roof for clearing fumes.
