Is it better to use timbers on concrete blocks, or just build the floor itself on the concrete blocks?
A wood deck is OK, but concrete is preferred for the manufacturer and you. Concrete is much more durable and easier to walk on and store things on. I have about a twenty year old shed that the deck is beginning to rot, and I am loathing the thought of removing the contents, moving the shed and repairing it. As far as the stone under the deck, I think it depends on the lay of the land. If it has a natural slope, and drains well, then stone can't hurt, as it slows the water evaporation, keeping the underside of the deck drier. It will also discourage skunks, groundhogs, etc from making it home. But if the ground is flat, and wet, then digging a hole is just going to be a constant pool of water under your shed, providing near 100% humidity all the time. Even though you fill the hole with gravel, only a portion of the water is displaced.
