I too am looking to build a shop. I mocked up a 24'x36' shop yesterday using graph paper. I drew out all the tools I could ever want to size and placed them into the mock shop. I tell you it will work but will propably be a little cramped. So now I am thinking just to play it safe I will build a 30'x40' shop. Like OhioDan said, figure out what size you need then go up to the next one. I think that if you build a 20x20 shop you will have enough room to store your tools and the project vehicle, but not enough space to work on it comfortably. That is about the space of my garage and before my wife took it over I would have to pull my 70 chevy out to work on it and would put it back into the garage to simply store it. I know you said you have limited room to build, but I would build as big as I could.
