I've got a couple of really deep IKEA bookshelves in my hobby room and I'm using one plane as a spray booth. I've stapled black plastic all arount the inside and added a small "lip" on the outside to catch rebounding paint spray. I've also added a light to the top.
The whole thing is only about 3ft by 3ft by 2ft but it works for general model work (airbrushing). If I need to used spray cans with toxic fumes I seal the whole thing with see-through plastic (ceran wrap works) and cut a hole for my arm. I think the largest prop I've used it for is my Pulse Rifle.
