Modern building made from Dollar Tree container

A while back I bought a foldable storage bin from Dollar Tree because it looked interesting as a possible building. Well, after some re-working this is what I have so far:

Front side- I havent finished the doors yet.

Back side- the door is hinged and opens

This is the second floor. When the roof comes off, the outside walls go
with it leaving an open floor plan. That design was dictated a bit by the
plastic crate, but I really like it.

This is the ground floor. Notice that the second floor comes off by itself.
In the back left corner you can just see the stairs.

 I haven't glued down any of the interior walls yet, that will happen after painting. Also please excuse the poop colored roof, i needed a thick paint for a tar and stone roof technique and that paint was the thickest I had. The more I look at it though, the more I dislike it and probably will change it soon.
As far as uses this is going in my town that I m building; usable for zombie games, Combat Zone, some post apocalyptic and the like.

Let me hear from ya,
