pole barn or something like the Amish bard you see on the side of the road for sale.i dont think a slab would work out .i stop to look at a prefab one that sit on 4x4 . 12x20 would be 3500.00
Wherever you decide to put the storage "shed," I'd highly recommend that you prepare the ground first, then have a truck come in a pour a slab. You'll never regret it. A dirt floor if you must, but there's nothing like a solid floor that can be swept clean when required, not to mention the ability to roll potentially heavy attachments around. My $.02...![]()
