Shop layout recommendations?

Years back I couldn't afford the lumber for my shop. 32x48. I started looking and found pool decks that people wanted removed. I gathered up many 12 foot 2x6's and my whole shop it pressure treated lumber. I got infested with carpenter ants from a dart sport I brought home, all they ate was the plywood and header. Used lumber is just as good as new. Just a little more labor. I wish I would have made it bigger. Like double the size.
