What do you recommend as a foundation?

It really depends on the size of the building, its location, and intended use, and local building code regulations. Most of our garden sheds sit on patio stones while garages are commonly placed on concrete pads if they are ordered with no floor in the building, but if the garage has a wooden floor and pressure treated skids it can sit on a gravel pad.
