The "Cayan Tower" is a luxury apartment building with a striking helical shape, turning 90 degrees over the course of its height. Each floor is identical in plan, but is set 1.2 degrees clockwise from the floor below, giving the tower a distinctive form by way of an innovative, efficient, repeatable structure. Its shape is pure expression of the relationship between a building’s form and the structural framework that supports it.
Aesthetically, the twisting shape makes the building stand out from the architectural disharmony of the Dubai waterfront, which is largely composed of indistinct towers that do not speak to their location. Located near Dubai Internet City, Emirates Golf Club, and numerous corporate headquarters, the tower’s twisting form provides a greater number of units with desirable views of the Dubai Marina and Arabian Gulf, while also preserving the views for residents living in neighboring buildings, ensuring that Cayan Tower enhances its spectacular waterfront site.
The tower’s structural system is a cast-in-place, high-strength, reinforced-concrete column superstructure. The shape and size of the columns were determined through the use of wind-tunnel testing and three-dimensional computer modeling to analyze building stresses. The building core is a cylindrical concrete form that acts as the central pillar for the tower. As the building ascends, the rotation at each floor occurs around this central mass. The building was constructed using a “jump form” system that takes advantage of its repetitive nature. Even so, construction took seven years.
