I'm getting close to pulling the trigger on building a new shop for my upcoming retirement years. I'm in the early planning stages. I want one long bay, big enough to pull the cab on a crew cab long bed and one or two smaller bays with another lift in one of them. I also want an enclosed bay that can serve as a wash bay and a poor boys paint booth. I also want a welding area and a place for my tire machine and wheel balancer. I also want a small office and 1/2 bath.

For those of you with shop experience, what are your suggestions, small or large as to items to think about at this stage of planning?
