Unless you’re a big fan of frequent shop remodeling, planning the layout of your workshop early in its development will save you a lot of time and trouble and also can keep you from spending years in an uncomfortable, poorly organized space. And if you already work in a shop that’s as organized as a trailer park after a tornado, careful planning and a little remodeling is likely to help you make a quantum leap.
My hand tools are stored in a cabinet built into my bench but my shop supplies, air tools, and a plethora of “misc stuff” is in a cabinet on the other side of the shop, and my clamps are mounted on a wall adjacent to my bench, where conventional wisdom says tools should be. I just like it that way. I run my DC overhead and drop down… because my floor is on a slab. My bandsaw is mobile so I can pull it out of a semi-alcove for resawing, otherwise it stays in place for small operations (20″ bandsaws are cumbersome to move, even on leveling casters).
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.
