As far as urban development is concerned, the question arose as to how, after reunification, the connection between the eastern and western centre of Berlin should look. The Berlin government quickly sold the plots to the former Daimler-Benz AG automobile group (1998–2007 DaimlerChrysler AG, since 2007 Daimler AG). Subsequently, the latter then attempted to assert an urban complex oriented to the tradition of Berlin which would be in the style of post-modern architecture. In contrast to this, the investors presented an alternative project of international star architect Richard Rogers and were able to assert themselves with their intensely concentrated concept of a 'city for the 21st century'. Potsdamer Platz became the largest construction site in Europe.
