The finishing exterior touches are underway on 111 West 57th Street, a 1,428-foot supertall residential skyscraper in Midtown and the world’s most slender building with a height-to-width ratio of 24:1. Designed by SHoP Architects and developed by JDS Development, Property Markets Group, and Spruce Capital Partners, 111 West 57th Street will yield 60 units designed by Studio Sofield and marketed by Douglas Elliman Development Marketing. The project is located on Billionaires’ Row between Sixth and Seventh Avenues, and is almost perfectly aligned with the center line of Central Park.
Since our last update in June, the construction crane has been fully disassembled and the gaps in the flat northern elevation left behind from the exterior hoist have been filled in. Only a few portions of the façade now remain to be completed.
Sidewalk scaffolding still remains around the base of the podium and Steinway Hall along West 57th Street and should be taken down sometime soon, perhaps by the end of this summer.
We can now see the final outcome of the northern elevation from Central Park as the glass panels span between the cast-in-place concrete walls. 111 West 57th Street has a set of four multi-story mechanical outrigger floors dispersed across its height to strengthen it against lateral and seismic forces. The openings in the envelope on the northern profile indicate their location and serve to break up vortex shedding. There is also a tuned mass damper tucked within thick concrete walls beneath the stepped steel-framed crown to counteract wind loads.
YIMBY last reported that 111 West 57th Street should likely be completed sometime before the end of 2021.
