Click the image at right, and start building the ideal workflow at the bottom where you see the first red arrow. This arrow crosses through one roll-up door of a typical two-car garage. Note that if the right-hand window were not present, you could place lumber storage closer to the entrance, which would also allow for easier passage onto the jointer. Work flows from the jointer to the planer and the table saw, then ideally onto an outfeed table near position #2 in the diagram. From #2, proceed left to the assembly area (pictured below).

Impact driver: I am a giant fan of impact drivers. I have been using them for a while now and can’t really remember my life before them (Click here to read more about my introduction to impact drivers). This is the one tool that I always have with me, and I expect to be within easy reach. So much so, that I own three of them and could imagine myself with a couple more. Like the chop saw, if this was a list of on-site or installation tools, the impact driver would be near the top.
Marc, would not assumptions for a Festool shop differ considerably? Far fewer big machines, and more carrying lightweight precision machines to the wood, for example. I only have a few Festool machines so far (took quite a while to get past the sticker shock), but I am beginning to see how it could change the way we work. My 400 sq ft shop is getting awfully crowded with floor-standing machines and implementing your guidelines, sound as they are, is difficult.

Let’s be clear about one thing: No workshop is perfect for everyone. If there were, I could simply give you a precise plan to follow with clear dimensions. Every person who comes to the hobby, avocation, or profession of woodworking has his own particular collection of tools and his own peculiar work style, skills, and desires for the kind of woodworking he wants to do that gives him a unique approach as to how he will lay out a shop: where the tools should go, where lumber and supplies are stored, and how much bench area he needs.
