Building a lean-to....
Not sure where you live, but here in "fire country" we are discouraged from storing firewood adjacent to the house. It also might encourage pests (insects, termites, ?) to enter your home.
That said, I have a small (8' * 44" footprint) lean-to made from 3 sheets of plywood. I don't know if that's the kind of thing you had in mind?
If so, if you want to post your address, I'd be glad to send you plans - or I can try to just describe it in words for you.

I apologize if this is a repeat post - I'm having trouble posting.
