One thing I liked about the Garden Coop was the hardware cloth ceiling under the floating roof. It allowed for a ton of ventilation which really helped in our super hot summers. (And kept out rats and mice!). I would side around your windows, so you can shut them during storms.
You can also plan it so you can keep the inner clean-out door open on the hottest nights. I had a clip where I could secure it open. Since the run is so secure, they don't need to be shut tight into the coop.
Didn't know about the floating roof. Ignore my opinion. I need to shut up more.
