Sky City 1000 is a hypothetical architectural project - specifically, a skyscraper envisioned in the Tokyo metropolitan area. It was announced in 1989 during the height of the Japanese asset price bubble. The plan consists of a building tall and wide at the base, and a total floor area of .〔(Sky City 1000 - Emporis )〕 The design, proposed in 1989 by Takenaka Corporation, would house between 35,000〔〔(Discovery Channel :: Extreme Engineering: Sky City )〕 and 36,000〔(SKY CITY 1000 )〕 full-time residents, as well as 100,000 workers. It comprises 14 concave dish-shaped "Space Plateaus" stacked one upon the other. The interior of the plateaus would contain greenspace, and on the edges, on the sides of the building, would be the apartments. Also included in the building would be offices, commercial facilities, schools, theatres, and other modern amenities.〔 Since its announcement, it has garnered a lot of attention from the world's architectural establishment, and was featured on Discovery Channel's ''Extreme Engineering'' in 2003. Land prices in Japan were the highest in the world at the time, and Kisho Kurokawa, one of Japan's most famous architects, has said that staggeringly ambitious buildings employing highly sophisticated engineering are still cheap, because companies pay 90% of the cost for the land and only 10% for the building.〔(Cities in the sky: New Scientist, October 2, 1993 )〕 Tokyo's only fire helicopter has even been used in simulation tests to see what the danger would be if a fire were to break out in the building.〔 Triple-decker high speed elevators which would be used in the building are also being designed in labs outside Tokyo.〔 Although this project has gained more serious attention than many of its alternatives, it can be considered similar to projects as X-Seed 4000 and to ultra-high density, mixed use concepts such as Paolo Soleri's Arcology and Le Corbusier's Ville Radieuse. If completed, Sky City 1000 would be the tallest man-made structure in the world, edging out the Burj Khalifa in Dubai. However, Jeddah Tower, currently under construction, is planned to be taller. ==See also== *Bionic Tower *Madinat al-Hareer 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sky City 1000」の詳細全文を読む スポンサード リンク
