This one is finally complete. 
The is a nice enough looking work of architecture; and the interiors are exceptional.
I find those blank metal panels next to each window a bit odd looking: but apparently they serve some sort of function. I think the idea is to provide an operable door to let in fresh air; without the need to create separate operable window panes that would divide-up the large single pane windows.
One of the largest “Single Pane” windows in NYC. The mullion-free (unobstructed windows) are gaining popularity as I am seeing them quite often lately.
The celebrity broker here does well in describing this apartment; and mentions those large single pane windows - “the largest in NYC”.
