The 65-story building will stand 1,005-feet when complete, according to developer Tishman Speyer

It’s official: Bjarke Ingels’s gargantuan Hudson Yards tower is moving forward. Developer Tishman Speyer filed plans for The Spiral on Thursday, The Real Deal reports. The 1,005-foot behemoth will rise at 509 West 34th Street and will stand 65-stories tall when its complete.

Its design is perhaps most notable for the vertical gardens that wrap all around the exterior of the building. The 2.2 million-square-feet office building will be developed at an estimated cost of $3.2 billion. Plans call for 27,000-square-feet of retail on the ground floor, and offices on floors two through 62. An anchor tenant has yet to sign on, but investment firm BlackRock is rumored to be eyeing some space in the tower.

Its height makes it just as tall as “the billionaire building,” One57, but at the Hudson Yards complex, it’s still only the fourth tallest of the planned buildings in the area. There were once rumors of an 1,800-foot tall tower known as Hudson Spire rising at this site, but those plans have since been abandoned.

There are a couple of points of discrepancy though. The Department of Buildings filing pegs the height of The Spiral at 962-feet with 64 stories, though a source informed Curbed that this may be a discrepancy relating to what’s on the roof. Additionally, while the property has 2.2 million zonable square feet, the project is being marketed as 2.85 million, which refers to the rentable square footage.
