i need some help.

I'm building a grotto style cage, but seriously i'm a little lacking in the creativity department, I would like to build one with two sections the top closed off for my girls, and the bottom closed off for O.P. I would like to use all of the same types of materials that were used to make the original grotto cage, but I want a bit of a different design, I would really REALLY appreciate any advice and i would ESPCIALLY appreciate pictures of already made cages to build up some ideas, my girls deserve a nice big home
