Sky City 1000

Sky City 1000 was a proposed skyscraper for the Tokyo metropolitan area. It was announced in 1989 at the height of the Japanese asset price bubble.

The proposal consisted of a building tall and wide at the base, with a total floor area of . The design, proposed in 1989 by the Takenaka Corporation, would have housed between 35,000 and 36,000 full-time residents as well as 100,000 workers. It consisted of 14 dish-shaped "Space Plateaus" stacked one upon the other. The interior of the plateaus would have contained green space, and the edges of the building would have contained apartments. The building would also have housed offices, commercial facilities, schools, theatres, and other modern amenities. Tokyo's only fire helicopter was even used in simulation tests to see what the danger would be if a fire were to break out in the building. If completed, Sky City 1000 would have been the tallest man-made structure in the world surpassing the Burj Khalifa.

History

In 2003, Sky City was featured on the Discovery Channel's Extreme Engineering.

In 2012, the Council on Tall Buildings and Urban Habitat (CTBUH) cited Sky City 1000 as one of several “visionary projects for vertical cities”. The proposed structure was designed to reach 1,000 meters in height and consist of 14 stacked “Space Plateaus”. It was intended to accommodate 36,000 residents and 100,000 workers, with integrated functions including residential, commercial, educational, and recreational spaces. The CTBUH also noted the project's “sustainable outlook that can help alleviate land problems and preserve the natural environment.”
