I like the idea of a door within a door a lot more that a split door/dutch door that involves the upper section. The door within a door should be very stable and anything else not so much.
Yeah I'm settled on that part for sure, no brainer when I think about it. Just trying to figure out door jamb design now, I think the sketch I posted would likely be the easiest and work but the floor is open for suggestions over the next few days.
