Rem Koolhaas, who once considered a career in film, reasoned that the most frequent view of these structures would be in motion, from the window of a car.
As the view changes, the towers, rising from a shared six-story plinth, separate and then merge.
The building consists of three interconnected towers that share a thirty feet high base which includes six floors.
The lower two layers form a large glass plinth.
At about 90 meters above ground the towers – known as West Tower, Mid Tower and East Tower– are shifted a few meters in different directions, which enhances the wind stability and provides space for terraces.
In the original design the towers did not touch each other, but in order to simplify the play of forces and to keep the construction affordable they are now connected in a few places.

The facade provides the option of natural ventilation.
On the west side there are balconies that are accessible from the apartments.
