That's a great example of how these things should be done. Keeping all the details and not cutting corners like with the National Art Galelry. Sadly, it probably already has graffiti on it. 
There's another great buidling nearby, getting a facelift - on Malyovitsa street (ends a Graf Ignatiev between Popa and Shishman). Seeing how it's going, I'm hopeful.
