Should also mention that you can never have "too many" electrical plugs. We put in quad 110volt every 4' along exterior walls and single 220volt every 10' (plus at machines as needed). We also have compressed air outlets plumbed in every 10' and two hose reels overhead (partly because we haven't finished installing all the air yet).

The shop is 42' deep and we have two work areas with 8' wide tables in the center with plenty of room for isles and cabinets on the outside walls. Each table has quad 110v electrical outlets on all 4 sides, 220v as needed with it's own sub panel so the table can be moved as a complete unit. Compressed air and port for dust vacuum hose will be added as well.

However, the very best thing I did was incorporate two 18' long utility trenches into the slab that dust control, electrical, compressed air and control wiring runs in. Those trenches (which are covered with removable 2x12 boards) allow for maximum flexibility in the layout of the shop and make adding utilities and repairs a breeze. Best of all there are ZERO electrical cords or vacuum hoses to trip over!!!!!

I spent a LOT of time researching the layout of other peoples shops before drawing up the plans for the one we just built. Very happy with the results.

I have NOT read the earlier replies, but strongly suggest white metal roofing for the ceiling; it's generally reflective. I also like the shiny white masonite used in some restrooms. Ceiling fixtures should be no closer to the exterior wall than two feet, to avoid your shadow when working hear a wall. Use LED lights of the "petal" type to avoid harsh shadows.
