Since the previous update in December, significant progress has been made on window installation at Foster + Partners' residential tower near the High Line, 551 W 21. Windows have reached the 15th floor at the 19-story, 44-unit luxury condo tower. The windows feature a metal surround and are set within a facade of white cast-concrete panels. Construction is slated for completion in the fall of 2015.
