I didn’t see any threads on this one, but one of the coolest renovations in progress is that of the old Emigrant Savings Bank located at 51 Chambers St.
Here is the wikipedia on the building itself: https://en.wikipedia.org/wiki/Emigrant_Industrial_Savings_Bank_building

This is a pretty massive renovation and they appear to be right in the middle of the transformation at this time.
