Beer crate architecture

This is a project at architecture school, build by minecraft. Real building should be build with empty plastic beer crates, that's the reason to use minecraft for simulation.
The task is to edit this basic spaces inside in your own flavor, but please don't make any huge changes to outside shape, because it has been already generated to specific shade casting at real site.
You can erase whole inside, or create narrow paths, small holes, whatever, just at the end of your editing, I would be glad if you send me your creation back, in comments. Your structure will be analyzed by stress analysis program to choose the best design able to be build.

Thanks for feedback and enjoy!
