When we built our house we built a large shop out back which my DH did not use that much for woodworking. He just had it more as a storage for his "junk". So he enclosed about a third of it for me a shop. It is completely contained with roof, walls, windows, ac, heater and TV. I love it, it is not fancy, but then neither am I. It is 11X17. He put inexpensive paneling on the walls, shelves, pegboard for hanging, 4X8 design wall, very large cutting tables. The cutting tables are large enough to put a 24X48 large ironing board at one one and still have plenty of room for a large cutting mat.
