Updated for version 7.x

I've added a garage and a basement.
Armored concrete upstairs, regular concrete below ground, armored windows.
I moved the constructors, storage, power, and food to the basement level. Med bay is also in the basement.

Main floor is mostly fluff. There is an oxygen dispensor, armor locker, and repair station there.

Elevators in the main building and the garage can take you to the basement. The elevator in the garage also goes to the roof.
