Help me design an enclosure(ball and papuan's)

[Elfmaze]

I'm trying to get off the aquarium's for my balls and near future additions. right now i have my adult male in a 50 gallon aquarium and the baby female ball in a 10 gallon. I also am looking to get into Papuan Olive Pythons(Apodora Papuana) And want to get two of them, a male and a female. I want to build a fairly roomy setup for all the snakes and want front opening designs but what dimensions do adult balls like? and what dimension do adult papuans like? i plan to make easy to clean but natural looking enclosures for all of them. all i' mlooking for right now are dimensions
