What Size Garage Would You Build?

[AU Doc]

Pretty simple question, with a complicated answer. I'm looking for recommendations on what size garage you guys would recommend building. I'm thinking two cars with two lifts plus plenty of space to work on stuff, store tools, and not be cramped. At some point I'd like to have a small lathe, CNC, maybe a mill? I haven't put much thought into that stuff and I don't have anything like that at the moment. I've got a pretty big yard, so that shouldn't be a factor. The cost, on the other hand will be. At this point I'm trying to get a feel for a good size so that I can start figuring out what it will cost me.

Thanks in advance!
