11 billion-dollar mega-projects that will transform the world's greatest cities by 2035

To accommodate growing populations, cities like Paris, New York, and Tokyo are building more housing and public resources, including parks, schools, and subways, as part of large redevelopment plans.

These cities will likely look very different (and in some neighborhoods, gentrified) in the coming decades. Take a look at some of the biggest urban projects under construction below.

Shanghai, China — Todtown

Set to be complete by 2020, Todtown is a new mixed-use development in Shanghai's Minhang District.

The development will feature 1,000 apartment units, a 1.3 million-square-foot shopping mall, an additional 580,000 square feet of retail, 1.5 million square feet of office space, and a 53,000-square-foot cultural center, according to InHabitat. Todtown will also incorporate lots of greenery, from green roofs to mini parks scattered throughout.

The master plan was created by Chicago-based architecture firm Goettsch Partners and Hong Kong-based studio Lead 8.

Construction on the $1.5 billion project began in 2014.

Cairo, Egypt — New Cairo Capital

East of downtown Cairo, New Cairo Capital will be a 270-square-mile hub with 21 new residential districts — enough housing for five million people.

The development is being financed largely by Chinese developers. (The China Fortune Land Development Company, for instance, put down $20 billion for the project in late 2016, according to CNN.)

New Cairo Capital will also feature 1,250 mosques and churches, a 5,000-seat conference center, nearly 2,000 schools and colleges, over 600 medical facilities, and what is projected to be the world's largest park.

Paris, France — Europa City

In 2016, Paris began building an 8.6-million-square-foot mixed-use development, called Europa City, north of downtown.

Designed by Danish architecture firm Bjarke Ingels Group (the company behind Google's California headquarters), Europa City promises housing, shops, and restaurants, though the exact numbers of each are not confirmed yet. The development is also slated to include plazas, an artificial ski slope, open walkways, a golf system, and a new transit system.

Gonesse, the suburb where it will be located, is still largely rural. But according to Europa City's developers, the goal of the $3.4 billion project is to connect the area with urban Paris and reduce congestion downtown.

Construction started in 2016 and is expected to wrap up by 2024.

Berlin, Germany — Europacity

Berlin is building a new neighborhood called Europacity. Spanning nearly 100 acres, the mixed-use development

Istanbul, Turkey — New City Istanbul

New City Istanbul is a development that re-imagines the 8,000-year-old river city.

In April 2016, the Metropolitan local news outlet The Daily Sabah reported. The 93.6 million-square-foot area was once a military zone.

The development will also feature a shopping center, a 6,200-space underground parking garage, a 26.9-million-square-foot park, a movie theater, an ice rink, and an airport that's being billed as the world's largest.

The exact timeline and cost for the project has not been disclosed yet, but construction began in late 2016. The airport alone, set to open in 2018, has attracted over $6 billion in funding.

New York City, USA — The World Trade Center site

Since the September 11 attacks in 2001, New York City has been working to redevelop the 16-acre Manhattan site where the Twin Towers and surrounding buildings stood.

As of July 2017, much of the project has been completed, including 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. Three more towers, a small church, and a performing arts center are still in the works. Construction is set to be finishedby 2020.

Los Angeles, California — Newhall Ranch

The Newhall Ranch development in Santa Clarita Valley will bring 21,500 residential units to Los Angeles County by 2035.

It will feature a mix of housing, including

While Los Angeles' pace of housing development is slowing in 2017, the city is still on track to meet Mayor Eric Garcetti’s goal of 100,000 new units by 2021. As Curbed notes, aAbundant Housing

São Paulo, Brazil — The city's new master plan

In 2014, So Paulo unveiled its new master plan, which will dramatically change the city over the next two decades.

The plan calls for more people-oriented development, including new housing, bike lanes, dedicated bus lanes, and a reduction in the number of existing parking spaces.

As Next City notes, the city currently faces a housing shortage of up to 500,000 units. Approximately 1.2 million
