The Spiral

At the north end of Hudson Yards, The Spiral does something most supertall office towers don’t bother with: it makes the outdoors part of the floor plate. Bjarke Ingels Group wrapped the 1,041-foot tower in a continuous ribbon of landscaped terraces that climb from base to crown, so every floor gets a slice of garden and open air. Tishman Speyer developed it, Turner Construction built it, and the building opened in 2023 as one of Manhattan’s largest new office addresses.

Project Scope

The Spiral rises 66 stories and holds about 2.85 million square feet of rentable office space on a full block between Tenth and Eleventh Avenues. The signature move is the cascading terrace that wraps the facade, fed by double-height spaces that let tenants open interior floors to the gardens outside. The roughly $3.7 billion project leaned on a steel frame and a high-performance curtain wall from Permasteelisa to pull off the stepped massing without giving up floor efficiency.

The tower anchors the western edge of Hudson Yards and connects to the High Line at its base, stitching a 1,000-foot office building into a public landscape. It carries a LEED Gold target, with the terraces doing double duty as amenity space and as a passive strategy for daylight and fresh air.

Why It Matters

The Spiral is a test of whether biophilic design scales to the supertall office. Outdoor terraces are easy at five stories and hard at sixty, where wind, structure and leasing economics all push back. Pulling it off at this height, and landing anchor tenants like HSBC and Pfizer, makes the building a reference point for a post-pandemic office market that’s asking towers to offer more than a desk and a view.
