What is claimed will be the fourth largest commercial office tower in New York is to be built in the city's developing Hudson Yards neighborhood. Covering 850,000 sq ft (79,000 sq m), 50 Hudson Yards will fill an entire city block and rise up to 985-ft (300-m) high.

Designed by Foster + Partners, 50 Hudson Yards will comprise three volumes stacked upon each other, creating a staggered structure and a variety of different floor plates – all column-free and able to accommodate a minimum of 500 people – within the building.

The building will be spread across 58 levels, with access provided on all four sides at ground level. Huge expanses of glass will make up the near fully glazed façades and will be framed by white stone cladding and the top of the building will be crowned by a "halo" that will be illuminated at night.

Top tier"marquee" tenants at 50 Hudson Yards will have the use of private sky lobbies, outdoor terraces, valet parking and private pick-up/drop-off areas. On-site bike storage and concierge services will be available to all building occupants and there there will be easy access to the rest of the Hudson Yards development, the outdoor observation deck located at the top of 30 Hudson Yards and the subway for commuting.

Hudson Yards is expected to be completed in 2025, and will feature a mix of residential, cultural, office and retail offerings, including a section of the High Line and the Vessel explorable artwork designed by Nelson Byrd Woltz Landscape Architects with Heatherwick Studio. It is estimated that 125,000 people a day will live, work or visit Hudson Yards.

Not only is the development said to be the largest private real estate development in US history and the largest development in New York City since the Rockefeller Center, it is also claimed to be one of the city's most complex developments so far. It is being built on two platforms above a working rail yard that will cover 28 ac (11 ha) in total. They will be held up by 300 supports that will be drilled up to 80 ft (24 m) into the ground.

Construction of 50 Hudson Yards is scheduled to begin next year and to be completed in 2022.
