Siding work is ending at 660 Fifth Avenue, a 39-story retail tower in Midtown, Manhattan. Designed by Kohn Pedersen Fox and developed by Brookfield Properties, the project includes extensive interior renovations to the 64-year-old building’s 1.25 million square feet of office space and the complete replacement of its mid-century curtain wall by a more transparent modern envelope. Turner Construction Company is the general contractor for the property, which is located along Fifth Avenue between West 52nd and 53rd Streets and was previously addressed at 666 Fifth Avenue. The promoter is aiming for LEED Gold certification.
New glass panels have reached the flat parapet since our last update in mid-April, when the top floors remained exposed. The work is now shifting mainly towards the completion of interiors. Retail stores along Fifth Avenue remained open as construction continued above.
Below are some aerial views of 660 Fifth Avenue taken from Midtown that show the progress of installing new equipment and mechanical systems on the roof parapet.
The following plan gives an idea of the scale of the massive window panels.
Passing clouds, sunlight and blue skies reflect off the glass surface, which is subtly divided by a narrow dark metal grid.
Glass railings line the top of the podium.
The only exterior section awaiting new cladding is on the lower half of the west elevation around the lower setbacks.
The revamp is expected to cost around $400 million and will include a new lobby, new elevators and infrastructure improvements. The largest floor plates are located in the podium of floors four through nine, with spans between 66,0000 and 70,000 leasable square feet per level. Floors 10 through 14 are approximately 40,000 rentable square feet each, and floors 15 through 39 produce 25,000 rentable square feet each.
Office facilities include 42,000 square feet of landscaped outdoor patios spread over four levels, on-site parking and bicycle storage. A separate lobby entrance along West 52nd Street will be dedicated to the major anchor tenant, who YIMBY says will also receive lighted signage at the top of the building that will be visible from top to bottom on Fifth Avenue.
660 Fifth Avenue is expected to be completed in December, as shown on the construction schedule.
