1 Manhattan West is a 67-story office skyscraper in the Manhattan West development. It was completed in 2019 and will serve as the second tower completed in the development after 3 Manhattan West.


In July 2018, Wells Fargo provided a $530 million construction loan for the project. The structure topped out in August 2018, and officially opened on October 30, 2019.

Architecture and design

The building is 67-stories, 2.1 million square feet and anticipated to achieve LEED Gold certification.

The structural system of the tower is composed of a central reinforced concrete core and a perimeter steel moment frame. Part of the tower overhangs the below ground train tracks leading into Penn Station. In order to avoid the tracks, the perimeter columns on the south, north, and east sides do not come down to ground level, but are transferred to the core above the building's lobby.


As of September 2019, the building was 86% leased:

  • Floors 6-22, 48: Ernst & Young
  • Floors 23-27: National Hockey League
  • Floors 28-46: Skadden, Arps, Slate, Meagher & Flom LLP
  • Floors 50-51: McKool Smith
  • Floor 56: Pharo Management
  • Floors 59-67: Accenture
