Tokyo’s Sky Mile Tower set to overtake Burj Khalifa in Dubai as tallest building in the worldReuters

If all goes as planned, the Sky Mile Tower set to be built in Tokyo Bay would be the tallest building in the world, beating the current record holder Burj Khalifa in Dubai. The project has been conceived in such a way that it would not only be a huge building, but will also be equipped with every prerequisite to make it a mini-city that can combat climate change.

Once the plan for the building is approved, it will be built to reach a height of 5,577ft which can hold up to 55,000 people. It is slated for completion in 2045 and once completed it would be twice as tall as Burj Khalifa with 2,717ft.

The tower will be surrounded by a series of man-made hexagonal islands which would act as a barrier to protect Tokyo from flooding as well as provide the foundation for homes for some 500,000 people.

They could be connected by Hyperloop, Elon Musk's high-speed transit system.

The tower's facade is designed to collect, filter and store water from the atmosphere so that there is no need to pump water to the top floors. Wind farms, solar panels and farms, where algae can be harvested and turned into fuel to provide electricity, are also planned.

There will be "multilevel sky lobbies where residents would share amenities such as shopping centres, restaurants, hotels, gyms, libraries, and health clinics," according to Architectural Digest.

The tower and satellite islands will be designed by Kohn Pedersen Fox( KPF), an American architecture firm and engineering firm Leslie E Robertson. Both are headquartered in New York City

The Sky Mile Tower project is yet to get approval.
