The tower in Vienna’s Donauplatte area complements the towers DC 1 and DC 2 by Dominique Perrault and offers 832 apartments for temporary living. The 100-meter-high building is connected on several levels to the existing Donaucity quarter.The projections of the three-dimensionally warped façade elements correspond to cozy alcoves, which frame the view of the Danube and the city in every room.
Not only the cramped spatial situation, but also difficult ground conditions and a tight time schedule intensified the general conditions for the foundation of the DC Tower 3. Soil quality, building density and the resulting lack of space on the construction site required special mechanical solutions.
The reinforced concrete skeleton with flat slabs is braced over the core in the longitudinal direction or over walls in the transverse direction. The window alcoves are prefabricated as modules and assembled on site. Aluminium slats structure the façade in the basement floors, from the ground floor onwards the tower is clad in aluminium sheets.
The 832 apartments extend from the first to the 32nd floor and are equipped with a sanitary unit, a workplace and a small kitchenette. The triangular protrusions of the metal façade are transformed into wooden alcoves on the inside, which serve as heated seat windows inviting residents to relax and enjoy wide views over the city.
