Demolition work is ramping up at 343 Madison Avenue, site of a 1,050-foot commercial supertall in Midtown East. Designed by Kohn Pedersen Fox and developed by Boston Properties, the 754,120-square-foot structure will yield 748,618 square feet of office space, 2,130 square feet of retail space, and 2,372 square feet of subterranean circulation paths to Grand Central Terminal and the future East Side Access project. The skyscraper is replacing a 105-year-old 15-story building between East 44th and 45th Streets that formerly housed the Metropolitan Transportation Authority headquarters.
At the time of our last update in early May, scaffolding already fully covered the existing structure. Since that time, thick black netting has been added, obscuring the brick and stone façade. It should only be a matter of time until the upper floors begin to be dismantled, and the building’s relatively short height could enable its full demolition to be completed by sometime this winter.
The current renderings of 343 Madison Avenue show a glass curtain wall with strips of angled spandrels for added texture and depth. At the bottom is a double-height lobby space and a corner entrance leading to the Long Island Railroad. The most prominent architectural feature of the design is the series of large multi-story trusses spanning the setbacks in the building massing. These sections are shown to be highlighted with bronze-colored walls and lined with landscaped terraces overlooking the Midtown skyline. The structure culminates in a rectangular glass volume housing a green wall tucked underneath a flat roof parapet.
The final rendering below looks north and toward the top of the eastern elevation, where the elevator core will be positioned. This section is defined by a rectilinear volume that will likely run the height of 343 Madison Avenue. Also visible are thin strips of glass that expose parts of the egress staircases, breaking up the monotonous use of rectangular metal panels.
Excavation for 343 Madison Avenue is expected to begin in 2022, and construction is anticipated to be completed by 2026.
