Yes, i should mention that around here, "shouses" (or as they're actually called around here, "shomes") are generally self-contracted and built from the ground up with varying plans, and their uses vary pretty radically....from what Dan describes above (the shed section simply being oversized garages or personal shops) to ones that are 75% a welding shop with a small living quarters.
I vacation sometimes at one of these in Alabama. The home part is a lovely 4 bedroom, 4 1/2 bath that would look right at home in an upscale neighborhood, but the back has a multiple warehouse-like sections with a giant garage storing boats, golf carts, and ATVs, a woodworking shop, an indoor gun range, and a bunkhouse with additional kitchen and bath.
