Just bought this and I am trying to recreate the Receptionist Scene (your very first example at the top-right).
I am using the tiles from Interiors_16x16.png, but I am struggling to get it to look like your example, while adhering to a 16x16 tile grid.
It looks like you deviated from that grid with either the stairs or the desk? You somehow tweaked the red carpet, which normally is longer, and I just can't figure out how to recreate the border around the edges of the elevator doors?
I am referring to the elevator that is shown on the left in this post:
