The World Trade Center site
Since the September 11 attacks, New York City has been working to redevelop the 16-acre Manhattan site where the Twin Towers and surrounding buildings stood.
As of January, 2017, 1 World Trade Center (also known as the Freedom Tower, the tallest skyscraper in the city), 4 World Trade Center, 7 World Trade Center, a new transit hub, the 9/11 memorial and museum, a mall, and a park are all complete. Two more towers, a small church, and a performing arts center are still in the works. Construction is set to be finished by 2020.
Essex Crossing
Located on Manhattan's Lower East Side, Essex Crossing will feature 1,000 apartments available to low-, moderate-, and middle-income residents.
The $1.1 billion development will also include a Regal movie theater, a new street market, a bowling alley, and a cultural space.
The once-abandoned site, which features many parking lots today, is the result of a failed 1960s urban renewal scheme by mid-century developer Robert Moses. Construction of Essex Crossing began in 2015 and is set to be complete by 2024.
Cornell Tech Campus
Cornell, the Ivy League university located in Ithaca, New York, is building a new campus that will dominate NYC's Roosevelt Island.
The development, which will feature dorms, offices, classroom buildings, restaurants, and a hotel, will span 2 million square feet.
Costing an estimated $2 billion, the campus will open in 2035. The university received $100 million in capital funding from the city to help build the campus.
Hudson Yards
Hudson Yards is a 28-acre mega-development that contains 33 smaller projects. The new neighborhood is expected to be completed in 2024, and will be comprised of residential units, retail, restaurants, office buildings, and a public square. The area will stretch from 30th to 41st streets and 10th and 11th avenues in Manhattan.
Costing an estimated $20 billion, the overhaul is billed as the most expensive real estate development in American history. Before the development broke ground, the area was a rail yard and offloading space.
Hunters Point South
Hunters Point South will be a 30-acre mega-development in Long Island City, Queens that prioritizes affordable housing — the largest of its kind in New York City since the 1970s, according to Curbed.
Over half of Hunter Point's 5,000 units will be offered below market rate. Gothamist reported that over 93,000 people applied for the apartments in 2015. The site will also feature a school, retail, restaurants, and a waterfront park with a ferry.
The project broke ground in 2013, with the second of three phases expected to be complete in 2018. There's no word yet when the third phase will be done, but so far, Hunter’s Point South has received over $2 billion in private investment.
Pacific Park
Formerly known as Atlantic Yards, the $4.9 billion Pacific Park project will bring 6,430 new apartments (2,250 of which will be priced below market rate), an eight-acre park, and a variety of shops to Prospect Heights, Brooklyn. The site already boasts the world's tallest modular apartment building, which opened in November 2016.
The full Pacific Park development should be complete by 2025.
Industry City
The current buildings and streets in Industry City, an industrial complex in Brooklyn's Sunset Park neighborhood, date back to the 1890s. But a major redevelopment project is set to give them a makeover — the revamped Industry City will feature a hotel, shops, and a 16-building hub for tech startups.
Construction started in 2012 on the multi-billion-dollar project, but developers have not announced a completion date yet.
