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 face it, one of the most significant costs of your shop will be its foundation. While you’re at it, what about adding space above your shop? There may be regulations preventing you from building living space above your shop if it is in an urban setting or in an outbuilding, but there may be some flexibility depending on where you live. It is in the municipality’s interests to encourage infill housing that uses existing infrastructure. At a minimum, think about including attic trusses to create some space above your shop for drying lumber or storing equipment. Access could be from simple pull-down attic stairs or from the exterior if you don’t want to lose floor space to a stair or ladder. If you’re creating an addition to your house, you may be able to add a couple of rooms you’ve always wanted, such as a family room, office or in-law suite.
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.
