I was in the server previously, it was hosted.
Everything is made out of 1x1x5 walls.
Also, it has just a very small amount of similarities with the real one. As a stand-alone building it's relatively nice, ignoring the walls, but if it's supposed to by a copy of the real thing, then it's very ugly.
However seeing this is your first post and I noticed your ID quite new in-game, nice job!
