I like the idea and interior quite a bit, but I had many problems with the logic for the doors and gravity elevators. Please fix the elevators so the floor doesn't open when you go up (currently: activate gravity generator>go up>ceiling opens>gravity is flipped back to normal and ceiling is under me>I fall on the ceiling and it opens, sending me back down) also the doors seem to close in my face/not open quite a bit. I'm still giving you 4 stars because this is easy to fix compared to creating the station which really looks nice to me. Oh and the hangar control room should have an activator connected to a not gate that controls the main hangar doors. maybe add a command room and a construction room with a build block too.
