Real or Photograph?

I recently came across this image on the internet. It’s a shows the lobby at 6 Pancras Square. It struck me because I was not sure if it was a photograph or a CGI. Turned out it was a photo. Then I was struck by the likeness we achieved in the images made before the building was finished!

You can see for yourself. The top image is the photograph and the bottom two images are CG images I created.
