One Manhattan West
One Manhattan West is a 67-story office skyscraper at 395 Ninth Avenue in the Manhattan West development on the West Side of Manhattan in New York City, United States. Designed by Skidmore, Owings & Merrill (SOM), it was completed in 2019 and is the second tower to be completed in the development after 3 Manhattan West. The tower is rectangular in plan, with a curtain wall that contains insulated glazing, as well as a reinforced-concrete mechanical core. Because One Manhattan West partially overhangs a set of railroad tracks, the mechanical core carries most of the building's structural loads.
One Manhattan West was built as part of the Manhattan West development, for which Brookfield Asset Management began acquiring land in the 1980s. Work on the building started in April 2015, after law firm Skadden, Arps, Slate, Meagher & Flom agreed to become the building's anchor tenant. One Manhattan West officially opened on October 30, 2019. As of 2022, a joint venture of Brookfield, the Qatar Investment Authority, and the Blackstone Group owns the building.
One Manhattan West, designed by Skidmore, Owings & Merrill, is 996 feet (304 m) tall. The building contains 67 usable stories, 2.1 million square feet (200×103 m2) and anticipated to achieve LEED Gold certification. One Manhattan West is located at 395 Ninth Avenue on the West Side of Manhattan.
The tower is rectangular in plan. The north, south and west faces rise vertically up from the ground, while the east face bows out until the 19th floor and then tapers in uniformly to the roof. The curtain wall contains insulated glazing; according to SOM design director Kim Van Holsbeke, this was intended to give the impression that the building had been milled from stainless steel. Most of the facade uses flat panels, while the eastern facade uses curved panels between the fourth and 19th floors. All four corners of the facade have a rounded transition with a radius of 107 inches (2,720 mm).
At ground level, there is a lobby measuring approximately 45 feet (14 m) high. The perimeter of the lobby does not contain columns, as the building's central core carries all of the structural loads through the ground story. The lobby is instead surrounded by a transparent wall, which is held in place by glass fins.
The structural system of the tower is composed of a central mechanical core of reinforced concrete and a perimeter steel moment frame. The walls of the mechanical core measure as much as 4 feet (1.2 m) thick. In addition, the building contains 75-foot-long (23 m) diagonal steel "kickers", which transfer loads from the core to the footings. Each kicker was manufactured in three pieces measuring 25 feet (7.6 m) long, allowing cranes to hoist them. Above the lobby, the building's structural system consists of steel floor slabs, which surround the core. Each story has a slab-to-slab height of 13.5 feet (4.1 m), and the office space on each story measures 42 feet (13 m) between the curtain wall and the core.
Part of the tower overhangs the subterranean railroad tracks leading into Penn Station. As such, the foundations cover only 30 percent of the site's area, and the southernmost 20 feet (6.1 m) of the lobby overhangs the railroad tracks. 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. Although the Manhattan West complex partially occupies a deck above the railroad tracks, the deck cannot support One Manhattan West's weight, so the core extends down to the bedrock just north of the tracks.
The core passes through the center of the lobby and is concealed by travertine walls. Near the lobby's ceiling, the core flares outward at a 45-degree angle. Stoneworkers used approximately 400 short tons (360 long tons; 360 t) of white Italian travertine in the lobby, and they used three CNC machines to carve the travertine. The elevator lobby, at the center of the mechanical core, is also clad with marble. The lobby also has black Canadian-stone floors and wood-paneled walls. The southern portion of the lobby contains a portion of a 240,000-square-foot (22,000 m2) retail area and a food hall, both of which are shared with 5 Manhattan West.
