Description: This building, almost twice the height of Sears, would have a resident population of 50,000. It is estimated that this tower would cost 10billion to build and have an impressive floor area of 1,039,206m squared.
The tower was the victim of the bursting of the real-estate bubble in Japan, but Foster maintains that he still hopes to build a version of this building. An unpublished variant of this design, conceived for a Shanghai site with Donald Trump, was called the M Tower.
Unlike the Millenium tower with it's central core, the M Tower would have a hollow centre, allowing sunlight to penetrate from one side to the other. Working with the Obayashi Corporation, the clients, they were able to demonstrate that the Tower would be able to be self-sufficient and even process it's own waste.
