Need help with an idea

So i have two dogs, one who is a little angel and doesn't get into trouble while im at work and the other that all he does is get into trouble. We have crated him (he destroyed it), he's on trazodone when im gone now but he still does some stuff. I want the angel dog to still have free access in the house and out to the yard but the other one I would prefer to keep outside. Any ideas of what I could do, that hopefully aren't expensive. We have a backporch, I was thinking we could do like a gate or something? For context the trouble dog is 2yrs old and 90lbs, he also prefers outside
