I had wanted to put a wood shed up on cinder blocks. Would add some height but also stop the poo and everything from getting on the wood itself and rotting it. Then I was going to leave it as dirt and deep litter right in the coop.
I never know though. Things sound good in my head then turn into a disaster. LOL
I think it is totally doable as a coop. Framing so you could have roosts can be done in a way to also add strength and rigidity. And without a giant ton of cutting wood.
