The modernization of this prime building in Midtown Manhattan features a state-of-the-art façade designed to maximize occupant comfort while reducing energy consumption.
660 Fifth Avenue’s current aluminum cladding will be replaced with a custom glass curtain wall that will provide mullion-free floor-to-ceiling windows from column to column, nearly tripling the window area provided to the office space and maximizing daylight and views. The wall also fulfills ambitious sustainable design criteria, optimizing performance of the building’s high-efficiency heating and air systems.
Inside, a reconstructed lobby with modernized elevators will include an active retail amenity. Numerous columns and low ceilings will be eliminated from the office floors to maximize interior space and provide double height spaces and interconnected floors, taking advantage of the building’s wide range of floor plate sizes. In addition to the façade and interiors work, the design team found opportunities in 660 Fifth Avenue’s existing massing – a podium and tower interspersed with multiple setbacks – to create exterior terraces at multiple levels on three sides, including an east-facing feature terrace along Fifth Avenue.
