If your shop will be attached to your house or another structure, it will likely need to match its foundation, tying the two structures together so that one does not structurally stress the other if they shift differently. That may dictate a poured concrete or concrete block foundation. Regardless of your foundation type, a cold concrete floor will sap energy away from the rest of the structure if you are not careful, so think about how to insulate it well before you build.
An interesting variation of this layout is displayed in Jim Tolpin’s shop, shown in the photo at right. Tolpin located his jointer to the left of his table saw, its height low enough to allow panels cut on the saw to pass over the jointer. To save space, his portable planer lives beneath the saw. All three tools are oriented toward the garage-style door, which can be opened to allow long boards to be ripped, jointed, or thickness planed.
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.
