If you''re attaching it to the house you'll need frost footing so it doesn't move in relation to the house. If it's free standing and not too big (ususally 24 x 24) you can get by with a floating slab. It cheaper to build a free standing if you don't need a lot of pavement to get up to it. Don't forget to get a nice paved apron in front and make sure it's wide enough and long enough for the cars to queue up there.
My brother got a slightly larger shed build from Cleary. They normally build the pole barn type building but for a premium they can put any siding you want on it and even a shingled roof. Since he lives in a subdivision where they can't have metal buildings he went that way and it looks just like a stick built garage from the outside, but cost quite a bit less.
