Love it or hate it, Hudson Yards is transforming New York City in an unprecedented way. With an estimated total cost of $20 billion, this megaproject has become the largest private real estate development in American history and the largest development in New York City since Rockefeller Center.

The expansive, 28-acre site sits on the rail yards bounded by 10th and 11th avenues and 30th and 34th streets. Developed by Related Companies and Oxford Properties Group in partnership with general contractors Tishman Construction and Tutor Perini, Hudson Yards is now giving rise to skyline-altering towers, high-end apartments, new public spaces, and more.

Here, we break down the massive megaproject by the numbers.

1 huge art installation

British designer Thomas Heatherwick crafted Vessel, a $150 million art installation that will sit at the center of the development’s five-acre public park. The design — nicknamed “Stairway to Nowhere” by the press — was unveiled in late 2016, and construction on the project broke ground in April 2017. It’s scheduled to open to the public later this month.

7 supertall towers

One Hudson Yards

This 33-story rental building on 30th Street between 10th and 11th avenues houses 178 apartments, ranging from one-bedrooms to a four-bedroom penthouse.

10 Hudson Yards

This Kohn Pedersen Fox-designed skyscraper was the first building to open within Hudson Yards in 2015. It’s 52 stories, 895 feet tall, and offers 1.8 million square feet of commercial space.

15 Hudson Yards

Designed by Diller Scofidio + Renfro in collaboration with Rockwell Group, 15 Hudson Yards will be home to 285 apartments starting around the $3.9 million mark — half of which have already been sold.

30 Hudson Yards

At 1,296 feet tall, it will be completed in 2019 and become the second tallest office building in New York. This will be the tallest of the megaproject’s skyscrapers and will be home to an open-air observation deck.

35 Hudson Yards

This mixed-use tower — which will clock in at just over 1,000 feet tall—is designed by Skidmore, Owings + Merrill’s David Childs and will be home to Equinox’s first concept hotel when complete.

50 Hudson Yards

When completed in 2022, 50 Hudson Yards will have 58 stories, making it the second tallest tower at Hudson Yards. It’s the work of British architect Norman Foster and is planned to house offices and retail space.

55 Hudson Yards

The architects at Kohn Pedersen Fox teamed up with Kevin Roche John Dinkeloo and Associates to create this glassy 780 foot high, 1.3 million-square-foot office tower.

25 highly-anticipated restaurants

The “Shops and Restaurants at Hudson Yards” will contain 25 different restaurants, many run by celebrity chefs like David Chang and José Andrés. The seven-story retail building was designed by Kohn Pedersen Fox with interiors by Elkus Manfredi Architects.

100th-floor observation deck

The 1,000-foot-high outdoor deck at 30 Hudson Yards, which will be the highest in the western hemisphere, is being constructed using 15 primary sections, each weighing between 35,000 and 100,000 pounds. It will feature a 7,500-square-foot view of Manhattan’s skyline, surrounded by a nine-foot-tall glass wall and a windowed floor.

200,000-square-foot cultural center

Hudson Yards’s forthcoming cultural center, exhibition space, and performing arts venue is being constructed at 15 Hudson Yards. The cultural center – known as The Shed — was designed by Diller Scofidio + Renfro in collaboration with the Rockwell Group. It features a retractable outer shell that can be deployed within five minutes to create a light, sound, and temperature-controlled space.

And that’s not all…

With ample controversy, sky-high costs, and so many people involved in the construction of this record-shattering project, Hudson Yards is certainly one to watch ahead of its slated completion in 2024.
