Architect Rem Koolhaas (Office for Metropolitan Architecture) presented the design for Rotterdam in the period 1998-2001. Developer Bouwfonds MAB tried to lease the Rotterdam, but this was difficult. In early 2006, Rotterdam real estate developer OVG was involved in the development of the Rotterdam. She entered into a development combination with Bouwfonds MAB. The development took place in early May 2007, due to an interest in the municipality of Rotterdam. They said that the municipal services now located at the Marconi Square should be housed in the building. On July 10, 2009, the municipality of Rotterdam and the project developers OVG and MAB proudly presented the final plans of the largest multifunctional building in the Netherlands; The Rotterdam. On December 14, 2009, the construction of the Rotterdam was officially launched.
