660 Fifth Avenue

Built

Raimund Koch

The modernisation of 660 Fifth Avenue, a prime building in Midtown Manhattan, features a state-of-the-art façade designed to maximize occupant comfort while reducing energy consumption.

The retrofit of 660 Fifth Avenue has adapted an outdated building to extend its life and improve performance. The office tower has been re-clad with large-pane glass windows of record-breaking size. Responding to the limitations of the original building, KPF’s design allows the structure to virtually disappear, makes the ceilings feel higher, triples the window area, and cuts annual operating carbon emissions by 54%.
