Reaching nearly 500 feet tall with a gross floor space area of over 1.7 million square feet, the giant glass towers consist of separate, shifted blocks that offer overlapping programmatic spaces. To avoid monolithic massing, OMA offset the stacked vertical towers into a “subtly irregular cluster that refuses to resolve into a singular form.” Designed with a focus on hyper-density and diversity, Koolhaas brings dynamic flexibility to the structure, a feature that’s reflected in its ever-changing, multiplicity of views.

In addition to 645,000 square feet of office space, De Rotterdam will also offer retail and restaurant space, a four-star 280-room lifestyle hotel with conference and event facilities, a 670-spot car park, and 240 apartments. Shared lobbies are located at the point of intersection between each block.  Wrapped in a glass facade with sleek aluminum mullions, floor-to-ceiling windows take advantage of sweeping views and natural lighting.

Once De Rotterdam is fully occupied, the owners estimate that an average of 5,000 people will be in the building on a daily basis. Residents will be able to move in by early 2014.
