So I'm looking to put a 6x8ft wooden shed on an empty bit of land I have in my garden and I was wondering if laying a few sleepers directly on the dirt would suffice for a base? I've done some reading and lots of people seem to suggest putting down a gravel base, then sand/cement mix and then patio slabs on top, but to me it just sounds like overkill for a shed I'll just be using to store garden stuff. My garden is also very steep so I'd like to avoid having to move a ton of gravel up and down the steps by hand. All I'm worried about really is the sleepers sinking over time.
