Millennium Tower (Tokyo)
The Millennium Tower is a proposed project for the construction of a building in Tokyo Bay, Japan.
Status
The Japanese company Obayashi commissioned Sir Norman Foster before the 1990s with a study of a building complex, isolated in the Bay of Tokyo, the standing in the sea and represent a separate town should.
Many years working the architects Foster and Partners, together with Obayashi on the architecture and design of the project. Finally, the concept was. The cost of the tower was estimated at about 10 billion euros. After the construction almost decided and completion was scheduled for 2009, the project was ultimately but postponed to an indefinite period.
Description
The design according to the 840 meter high vertical city to be built on an artificial island 126 meters wide and the foundation wants to anchor in 80 feet of water in the ocean floor. On an area of about 12,500 m² to 50,000 inhabitants should after 10 years of construction, housed and jobs for 17,000 people to be created. The usable area for homes, offices, shopping centers, restaurants, cinemas, concert halls, hotels and for many sports facilities, will amount to nearly 1,000,000 m² according to plans of architect. Had the construction took place as originally planned, the tower 840 meters above sea level at this time would be the tallest building in the world.
The tower, a circular cone-shaped body, is divided into seven parts. The lower 600 meters of the building comprise 150 floors. These are divided into five equal zones of high and will take office at the top of flats and in the lower part. The comprehensive five floors each containing 25 blocks are separated by four " city centers ", with five storeys high, from each other. These centers are semi- public areas, terraces, hotels, restaurants, sports centers and shops and are used mainly to supply the city. The first floors will be manifold equipped and form the completely public area of the tower. Here housed leisure centers are also the people of the mainland attract. The plan also provides for a circular marina around the building, so the overall diameter is at the bottom correspond to about half the height of the Millennium Towers.
The conical shape of the structure has been chosen for several reasons. First, one can thus achieve a reduction in wind loads, which offers an ever decreasing windage with elevation. On the other hand is a pyramidal structure of high buildings a very stable structure during earthquakes.
