The Millennium Tower

The Millennium Tower (Japanese: ミ レ ニ ア ム ・ タ ワ ー; Mireniamu Tawā) is a proposed project for the construction of a building in Tokyo Bay , Japan .

status

The Japanese company Obayashi commissioned Sir Norman Foster with a study of a building complex that was to stand in isolation in the bay of Tokyo in the sea and represent an independent city.

For many years, the architectural firm Foster and Partners worked with Obayashi on the architecture and construction of the project. Finally there was the concept. The cost of the tower was estimated at around 10 billion euros. After the construction was almost decided and the completion was planned for 2009, the project was finally postponed indefinitely.

description

According to the design, the 840-meter-high vertical city is to be built on an artificial island and the 126-meter-wide foundation is to be anchored 80 meters below the sea floor. After 10 years of construction, up to 50,000 residents were to be accommodated on an area of ​​around 12,500 m² and jobs for 17,000 people were to be created. The usable area for apartments, offices, shopping centers, restaurants, cinemas, concert halls, hotels and many sports facilities will, according to the architects' plans, be almost 1,000,000 m². If the construction had taken place as originally planned, the tower with a height of 840 meters would have been the tallest building in the world at that time .

The tower, a circular cone-shaped body, is divided into seven parts. The lower 600 meters of the building have 150 floors. These are divided into five equally high zones and are intended to accommodate apartments in the upper part and offices in the lower part. The five blocks, each comprising 25 floors, are separated from one another by four “city centers”, each five floors high. These centers are semi-public areas with terraces, hotels, restaurants, sports centers and shops and are mainly used to supply the city. The first floors should be equipped in a variety of ways and form the completely public area of ​​the tower. Leisure facilities located here are also intended to attract the residents of the mainland. The plan also includes a circular marina around the building so that the total diameter at the bottom will be about half the height of the Millennium Tower.

The conical shape of the structure was chosen for various reasons. On the one hand, a reduction in wind loads can be achieved in this way, which offers a smaller and smaller area exposed to wind with increasing height. On the other hand, a pyramidal structure of tall buildings is a very stable construction in the event of an earthquake .
