They snuck an extra floor in there. From 4 stories to 5.
I've seen the facade saving thing done here with all that external bracing, but then they use the facade as an actual exterior wall. It looks a little funky but is much better than tearing it all down. This just looks moronic.
I found historical imagery of the construction site a few blocks away. You can see all the bracing of the facades on both sides of the street, and the finished products in the current street view.
I think they did a better job on this one than on that example in London.
