Well , sort of a 1 car basement garage - the wagon on one side, compressor and work benches on the other side which has no outside door. I store a lot of stuff in the other half of the basement, leaving Judy enough room for the washer & dryer - priorities you know! Luckily I have a 12 x 16 storage building which is adequate.
I guess that if you have a huge interest for something you can be satiesfied with a small shop as long as you can work on your car. Larger shop = more junk! At least here in Sweden.
