restaurant and bar house - in progress

hi all, this is an almost complete model of an actual building i Bergen, Norway.
Originally built as an FPS, this has now evolved into a virtual tour of the building, where potential customers can browse the bars and restaurants etc, check their different menu`s and concepts, reserve e a table, or leave feedback.
The FPS game is still being worked on too. this will feature the same model, but flickering lights and zombie waiters wandering about the building.
still quite a bit to do, and am looking for volunteers for lighting and texturing, and just someone to place furniture about the place (have already posted in the volunteer forum.)

modellers used for this project are the following:

here are the others

Looks cool! How did you get the cutouts for each floor? Did you model them on different layers?

yes, they are modeled on each layer
