Foundation work is almost finished at 100 West 37th Street, the site of a 68-story mixed-use skyscraper in the Garment District of Midtown, Manhattan. Designed by C3D Architecture and developed by Sioni Group under the 989 Sixth Realty LLC, the 743-foot-tall structure will span 384,118 square feet and yield 300 condominium units with an average scope of 991 square feet, as well as 86,817 square feet of commercial space and two cellar levels. The property is alternately addressed as 989-993 Sixth Avenue and located at the intersection of Sixth Avenue and West 37th Street.

A tremendous amount of progress has taken place below grade since our last update in early June, when excavation was still occurring across the majority of the lot. Recent photographs show much of the inner substructure already formed and massive bundles of rebar protruding in the locations of the forthcoming columns and perimeter walls. Based on the pace of progress, it’s possible that construction could begin to rise above street level before the end of summer.

Renderings of the skyscraper from Render.bar depict the slender glass skyscraper beginning with a multi-story podium composed of two conjoined glass-clad cylindrical volumes topped with a wraparound landscaped terrace. Above, the main tower rises largely uninterrupted with only a handful of shallow setbacks that will be home to private terraces. The eastern elevation features a subtly curved surface enclosed in a uniform glass curtain wall with light mullions, while the other sides are flat, indicating the location of the core walls. Stacks of curved balconies line the northeast, southeast, and southwest corners of the upper stories, and the building culminates in a mechanical bulkhead adorned with illuminated horizontal grilles.

100 West 37th Street’s anticipated completion date is posted on site for 2026.
