I have a coop of this design, I don't know if it's the same dimensions but it looks the same, I use it for quarantine and chicks because there is no way it's big enough as a permenant coop, in fact once my new coop is built and the one I'm using is free I'm making the one like yours a guinea pig hutch
This is an old picture of a hen using it for quarantine, it was barely big enough for just her!
