Holy Puzzle Pieces Batman!!

I got my 3rd Kato building in a lifetime and it was the 23-431 Built-Up 4 Floor Office Building, Green. I thought to myself thats a cool little building to have on my layout so I bought it. I was playing around with it and noticed that the floors separated, chi-ching I can add more floor and make it a high rise or a low rise anyways I thought it was pretty cool and had to share.
