THE HIGH LINE MEETS THE SKYLINE

The tower will cover a full block, stretching from West 34th Street to West 35th Street, and from 10th Avenue to Hudson Park. It will be located near the intersection of the High Line elevated park and the 1.6 hectare Hudson Boulevard Park.

Climbing 306m, the tower's design draws from both historic and contemporary design styles.

"The Spiral combines the classic ziggurat silhouette of the premodern skyscraper with the slender proportions and efficient layouts of the modern high-rise," said Danish architect Bjarke Ingels, founding partner of BIG.

The tower's signature element is a series of landscaped terraces that ascend in a spiral, forming a continuous green pathway around the building and providing tenants with outdoor space.

"The Spiral will punctuate the northern end of the High Line, and the linear park will appear to carry through into the tower, forming an ascending ribbon of lively green spaces, extending the High Line to the skyline," said Ingels.

From the base to the pinnacle of the tower, every floor is designed to open up to the outdoors through "hanging gardens and cascading atria" that connect the open floor plates, Ingels added.

The tower will encompass 265,000 sqm. Amenities include double-height atria, expansive views of the city, and flexible layouts.

Floors can be opened up and adapted for tenants who want to occupy multiple stories. "This element offers an alternative to elevators, thus encouraging physical activity and enhanced interaction among colleagues," said the developer in a statement.

The building's six-storey podium will contain retail space totalling 2500 sqm, along with a large "amenity terrace" on the seventh floor. Ceiling heights in the building's lobby will reach 9m.

Tishman Speyer, a global real estate firm, is backing the project. The firm's portfolio includes iconic New York projects such as the Chrysler Building and Rockefeller Center.

"Working with Bjarke Ingels and his team, we have designed a tower that offers stunning green spaces to all and will serve as a significant leap forward in the evolution of the modern, collaborative and sustainable workplace," said Rob Speyer, CEO and president of Tishman Speyer.
