The new glass curtain wall has begun installation on 660 Fifth Avenue, a 39-story commercial building in Midtown, Manhattan. Formerly addressed as 666 Fifth Avenue, the office tower is in the process of having its mid-century façade replaced with a modern envelope in a project designed by Kohn Pedersen Fox and developed by Brookfield Properties. The 1.5-million-square-foot property is located between West 52nd and 53rd Streets.
Since our last update March, most of the old façade has been stripped away and the new curtain wall is now rising on all four sides of the tower.
Recent photographs show the former and new skin of the edifice, while portions of the steel superstructure are temporarily exposed. Kohn Pedersen Fox’s design approach aims to utilize the full span between each perimeter column as opposed to the compact grid of rectangular windows and decorative reflective aluminum panels that once fully covered the office tower.
Tall sidewalk scaffolding still wraps around the storefronts of Zara, Hollister, Tissot, and Uniqlo along Fifth Avenue, while black netting remains around the podium levels. The new floor-to-ceiling windows measure 11 feet tall by 19 feet wide and are currently protected with thin plastic sheets on the inside.
Renderings below offer a glimpse of the views from the top floors looking north toward Central Park. The modern fenestration will allow for optimal daylight exposure and create a much sleeker finish. The setbacks on the lower half of the tower will be topped with numerous landscaped outdoor terraces for occupants.
Access to the 5th Avenue-53rd Street station, which is serviced by the E and M trains, lies directly below the site, while the B, D, and F trains can be found underneath the nearby Rockefeller Center to the south.
660 Fifth Avenue is predicted to be completed in 2022, as noted on the project’s main website.
