With a height of 1,000 meters and a total floor area of 800 hectares, Sky City is a super high-rise city comprising 14 concave dish-shaped, aerial bases called "Space Plateaus" stacked one upon the other.

Features

Residences, offices, commercial facilities, schools, theaters and so forth are organically located in these spaces. 35,000 people will reside here, and 100,000 people will work here.

The interior of the plateaus would contain green space, and on the edges, on the sides of the building, would be the apartments along with offices, commercial facilities, schools, theatres etc.

Challenges

Sky City's rounded shape would deflect some winds. To counter the sway, the engineers have to design active dampers on a scale never attempted before.

Fire simulations are being examined to estimate the threat to the 35,000 residents. Triple decker high speed elevators, which will hold up to 70 people, are now being designed at experimental labs outside of Tokyo.

Each Space Plateau will have its own train circum navigating the plateau.

Tokyo's only Fire Helicopter is now being used in exercise drills to test the ability to fight fires in such a tall structure.
