Thank you for sharing this, it looks smart and interesting. I especially like the "control tower" and that ramp for the upper level of the parking lot. As a whole, it looks so "real" (which is a compliment in my vocabulary ).

@Floraflora2 Glad you like it. The only thing I can think you may want to do to make it look more "real" is to add some trash cans to upper floor and near vending machine. However, since when your sims actually consume candy/soda they don't generate trash(wish that happened in "real" life) this is merely a deco choice.
