The changes I made mostly affect the front facade.
I added vertical fins and are colored red. The black ones are horizontal the vertical ones are fixed onto them. The black ones are recessed a little bit compared to the red ones to provided space for signage.
Behind the fins is the original color as I saw no need to get rid of it. The same goes for the sides and the back.
For the parking, it is angular and its one way. The angle is 45 degrees
