Personally, I don't like the wood floor in the bottom of the coop design. We used to have a wood floor, and it ended up rotting, so in our new coop, we put a concrete floor in. It's fairly expensive, but it will make your coop last a lot longer (our old coop lasted about 5 years, and that was a stretch). Our old coop was like a raised shed, but our new one matches our house (it even has a bay window and siding), it really depends on what you want, but the way I see it, the nicer the coop, the longer it will last... Just a thought.
