Tishman Speyer's 2.8 million-square-foot office behemoth at 66 Hudson Boulevard officially topped out Tuesday. The 1,031-foot building, dubbed "The Spiral," is a Bjarke Ingels Group design occupying an entire city block between West 34th and 35th Streets and stretching from 10th Avenue to Bella Abzug Park. The glass and green adorned tower was first revealed in 2016 and has been swiftly on the rise since breaking ground in 2018.

Although situated among numerous starchitect-designed supertalls, The Spiral stands out with its wrapping terraces and hanging gardens. Inside, tenants will be afforded generous open floor plans, soaring ceiling heights, and guaranteed access to the outdoor areas at every level.

The Spiral is expected to open in 2022, at which time anchor tenant Pfizer will establish its global headquarters across 746,000 square feet and 14 floors. Law firm Debevoise & Plimpton LLP and management firm AllianceBernstein are also moving in, leasing 531,000 square feet and 166,000 square feet, respectively.

As it stands, about 49 percent of 66-story structure still needs to be let, including both office space and the ground floor retail.
