Information about the restoration of this building here and here (sorry, only in German language).
Main point is, the building in this image had been damaged heavily in the war and what you see here is the restored facade. The Berlin office for preservation made it a must to keep the scars of the war. The first link above (with lots of images included) show the extensive works on the building trying to balance the historical impact with the restoration purposes.
