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 An unpublished variant of this design,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.
