Cat brings up a good point and I hadn't thought about it. All I know is there are lots of windows and you never have a closed in feeling. Another thing I like (because I was by myself a lot during the first 9 months) if you have the small window by the door with blinds up or only dayblinds down you can see who is knocking on your door. I think this is a real safety issue.
Happy trails.........................
