Go bigger than you think. A 12x24 or larger gives you room for a table saw, a workbench, a lumber rack, and space to actually move around a full sheet of plywood. Woodworking eats square footage fast.
A garage-style building with an overhead door is ideal. You can slide sheet goods straight in, get cross-ventilation when you're finishing, and open it up when you need extra room on a big project. Heavy-duty electrical is a must: 220V if you're running a table saw, planer, or dust collector. And that solid Amish-built floor will hold whatever you put on it without flexing.
