Bjarke Ingels continues to write his west side story with yet another icon along the Hudson River. Today, developer Tishman Speyer unveiled the architect’s design for The Spiral, a 65-story, 2.85 million-square-foot office tower.

The tapering glass high-rise, to be situated where the High Line intersects with Hudson Boulevard Park in the new Hudson Yards district on Manhattan’s west side, will feature a continuous half-mile-long terrace level of hanging gardens that wraps the tower from base to summit. This “ascending ribbon of green,” according to Ingels, will extend “the High Line into the skyline.”

Tishman Speyer—whose portfolio includes Rockefeller Center and the Chrysler Building-- says that it has secured more than $1 billion from investors for the project. A groundbreaking date has yet to be determined.

Ingels, founding partner of BIG, says it will be a “a new tower that stands out amongst its neighbors, yet feels completely at home.”  

It will certainly be at home in BIG’s portfolio: about a mile upstream on the Hudson, the firm is preparing wrap up 625 W. 57th Street, or Via W57, a pyramidal residential tower.

The scheme for The Spiral—with its emphasis on flexible, open work spaces, and ample access to outdoor terraces, is reminiscent of BIG’s design for 2 World Trade Center, unveiled last year. The building lost its anchor tenants—21st Century Fox and News Corp. –last month; the future of its design remains unclear.
