POLYGON - Coffee Shop

This is just a parody for simple town coffee shop.

You will get a coffee shop, a table and a chair. They looks nice as always but none of them has collisions. Adding colliders to chairs, doors and table is easy but when it comes to the shop itself.. oh lord!
Since the whole shop is one huge model you can't disable walls or furnitures. Addig colliders to it is just painful.
Tip for users: use primitive box so you can more freedom rotating it around to make the stairs working.
For SYNTY:
Please make it modular with colliders. It looks wierd that the second floor has no windows, the balcony should be optional too. The counter and the self behind it should be a separate model as well. I know it's free but requires a lot of work to make it functional (for a first or thrid person game) and it should be working "out from the box".
This package should contain:
-A wall piece
-A windowed wall piece
-Whole window piece (the one thats on the second floor between the balcony)
-Front door piece
-Back door piece
-A floor piece
-The counter
-The shelf
-Stair piece (separete or the whole L shape)
-Balcony corner piece (with L shape fence)
-Balcony "middle" piece (with | shape fence)
-Balcony pillar piece
-Huge coffee mug piece
-Air conditioner piece
