Tishman Speyer and investment manager AllianceBernstein (AB) announced that AB will lease 189,000 s/f at The Spiral, the 65-story office tower under development at 66 Hudson Boulevard in Manhattan.
Beginning in January 2025, the financial services firm will occupy floors 25 through 28 under a 20-year lease agreement.
It’s the second big deal at the 1,031 foot office tower currently rising on Midtown’s West Side. In 2018, Pfizer biopharmaceutical company agreed to relocate its global headquarters to 800,000 s/f within The Spiral upon its completion in 2022.
Designed by BIG-Bjarke Ingels Group, The Spiral will feature a cascading series of landscaped terraces and hanging gardens . The terraces will ascend, one per floor, in a spiraling motion to create a continuous green pathway that wraps around the façade of the tower and supplies occupants with readily accessible outdoor space.

Tishman Speyer President and CEO Rob Speyer said, “Tishman Speyer is thrilled to welcome AllianceBernstein, which was attracted to The Spiral in part due to Bjarke Ingels’ unique and inspired design. With its iconic architecture, technological innovations, top-tier amenities, amazing views and abundant access to outdoor spaces, The Spiral is raising the bar for the 21st Century creative work environment.”
“We embarked on an extensive search to find the right space for AB. We believe that The Spiral will help us to achieve a workplace that is equipped with collaborative tools, flexible open spaces, and state of the art staff amenities and innovative technology, all of which will help us to best serve our clients. We are looking forward to making The Spiral our New York City home,” said Seth Bernstein, President and CEO of AB.
Located at the intersection of the High Line and the four-acre, recently renamed Bella Abzug Park, The Spiral will encompass a full block stretching from West 34th to West 35th Streets and from 10th Avenue to the park. The six-story base of the building will include a lobby with ceiling heights of up to 28 feet and main entrances on Hudson Boulevard East and 10th Avenue. The base also will include approximately 25,000 square feet of first-class retail.
AB was represented by Newmark Knight Frank brokersNeil Goldmacher, Jared Horowitz and Brian Goldman. Tishman Speyer handled the deal in-house.
