It would house 50,000 people and contain gyms, hotels and health clinics

Would be twice the height of world's tallest building, Burj Khalifa in Dubai

Its centre piece would be the 5,577ft high skyscraper, the Sky Mile Tower

There are plans to build an extraordinary one mile high (5,577ft) skyscraper in a Japanese 'mega city' being dubbed 'Next Tokyo'.

It would be more than twice the height of the tallest building in the world, the Burj Khalifa in Dubai, which stands at 2,717ft high.

The structure known as the Sky Mile Tower would be the crowning centre piece in Next Tokyo, a futuristic city which is being built to combat climate change.

The Sky Mile Tower would be more than twice the size as the current tallest building in the world, the Burj Khalifa in Dubai, which stands at 2,717ft high

The 'mega skyscraper' is expected to house 55,000 people who will have access to its 'sky lobbies' which will hold shopping centres, restaurants, hotels, gyms and even health clinics.

It is being built in a hexagonal shape because the shape is the most wind resistant, Architectural Digest reported.

Its elevators will not only carry people vertically from floor to floor, but horizontally to their apartments also.

Architects developed a special way of distributing water to people one mile high up by creating a facade that collects, treats and stores water at different levels.

Next Tokyo's developers believe the sale of its waterfront properties could even hep pay for the project's construction, if the proposal is approved.

The city itself, expected to be completed by 2045, will house around 500,000 residents who are looking to leave their high-risk coastal homes and reduce their commute.

The Burj Khalifa (left and right) in Dubai has been the tallest man made structure in the world since its completion in 2009

It would be made up of several hexagonal, man made islands which will hold farms, homes and solar panels.

The city could be connected by Elon Musk's high speed transit system known as Hyperloop, according to an academic study by Council on Tall Buildings and Urban Habitat.

Water filled rings will be used to grow algae, which is said to be a renewable and clean energy source.
