Within the agenda of sustainable urbanism the architects had to integrate the nearby Georg-Brauchle-Ring underground train station within the basement of the 38-floor tower.
The signature tower was supplemented by four atrium buildings and a campus surrounded by landscaped public space.
In November 2004, a referendum in Munich was held to decide whether the construction of high-rise buildings in the inner city should be prohibited.
In August 2006, the skyscraper and one of the campus buildings was bought by the Government of Singapore for more than €300 million.
[citation needed] In 2017 the building was sold to Europa Capital and Bayern Projekt.
