The Spiral, the 65-storey glass tower is slated to rise as part of the massive Hudson Yards mixed-use development on the west side of Manhattan. Climbing 306 meters, the tower's design draws inspiration from both historic and contemporary design styles. The Spiral, designed by BIG, combines the classic ziggurat silhouette of the pre-modern skyscraper with the slender proportions and efficient layouts of the modern high-rise. The tower is currently under construction.
The tower's cascading gardens are being referred to as "the evolution of the modern, collaborative and sustainable workplace." The terraces will ascend, one per floor, in a spiraling motion to create a unique, continuous green pathway that wraps around the façade of the tower and supplies each occupant with readily accessible outdoor space.
The building will offer 264775 square meters of "connected and sustainable Class A" office space. The building's six-story podium will contain retail space totaling roughly 2,500 square meters, along with a large "amenity terrace" on the seventh floor. Ceiling heights in the building's lobby will reach nine meters. 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.
