My new house has a pretty big garage already, but I'm going to grow it even bigger. In the end it'll be basically an extra wide and deep 2-car wide, 2-car deep deal, like 28'x60'. It'll have two 9' doors on the front, and a single 16' door in the back. I plan to put most of my benches and stuff in the middle, so I can have four vehicles parked, nosed in toward the benches. I plan to get insulated doors, and insulate the walls and ceiling and cover with galvanized steel panels ("barn tin"). Since this is an attached garage, I plan to plumb gas in there for a heater (it gets cold here). I plan to route all electrical externally in conduit and also route compressed air in pipe so I can tap in in various places. I'm still thinking about how to house the compressor so I don't have to hear the noise at full volume - maybe an insulated box of some kind. Any suggestions for other features I should think about while I'm still in the planning stages?
