I have actually thought about stacking so as to come up with a shed/shop (mowers and saws), just add some tin on top. Sort of dual purpose. Use the wood for like five years out. workbench, stacked wood with some planks or plywood on top, etc. Doghouses. Lot you can do with stacked wood thinking about it. Have to stack high and careful for a garage though.
