OMA completes De Rotterdam
OMA today marks the completion of De Rotterdam, a mixed-use, 160,000m2 slab-tower conceived as a 'vertical city' on the river Maas.

Ellen van Loon: "Efficiency has been a central design parameter from day one. The extreme market forces at play throughout the course of the project, far from being a design constraint, have in fact reinforced our original concept. The result is a dense, vibrant building for the city."

With the building's completion, a critical mass has been established on the Kop van Zuid, realizing the long-established vision of a second city center south of the Maas. The building is named after one of the original ships on the Holland America Line, which from 1873 to the late 1970s transported thousands of emigrating Europeans bound for New York from the Wilhelmina Pier, next to which De Rotterdam is situated.

The three stacked and interconnecting towers of De Rotterdam rise 44 floors to a height of 150 meters and span a width of over 100 meters. Nevertheless, the building is exceptionally compact, with a mix of programs organized into distinct but overlapping blocks of commercial office space, residential apartments, hotel and conference facilities, restaurants and cafes. Office employees, residents and hotel guests are brought together in conference, sport and restaurant facilities. The building's shared plinth is the location of the lobbies to each of the towers, creating a pedestrianized public hub by means of a common hall.

Rem Koolhaas: "Despite its scale and apparent solidity, the building's shifted blocks create a constantly changing appearance, different from every part of the city. The fact that it stands today represents a small triumph of persistence for the city, the developer, the contractor and the architects."

The various phases of design and construction were supervised by partners-in-charge Rem Koolhaas, Ellen van Loon and Reinier de Graaf, and associate-in-charge Kees van Casteren. De Rotterdam is developed by MAB Development and OVG Real Estate.
