I don't have pics, but have read that someone used a childs metal bunkbed frame for a small coop. Used a couple of scraps of plywood for the nest/roosting area and chicken wired the whole thing. You would end up with an 20sq ft run area on lower part. You could get creative with that framework.
If you look at "My Coop" on my profile, everything except for tarps, chicken wire and hardware(screws and latches) were re-purposed from thing around my house and other peoples house. The dog run panels are from my SIL. Wood left over from paintball field bunkers and extra from under my carport...
