Three towers as polygonal individuals were planned in the area around Maag-Areal, City West, Zurich: the office building "Prime Tower", the Hotel and residential building "Mobimo Tower" (both of which exist on the site), as well as the "Zölly" building, which is concerned with the combination of private living and outside space within a high-rise building.
In a classical manner, the residential tower is organised by plinth, principal floors and attic storey. Through the principal floors, storeys can be read in groups of three; an order which serves the legibility of the building at an urban scale. This division also establishes a correspondence with the narrow faces of the polygonal volume, whose dwellings, with their over-high living rooms, are always combined into three floors.
The facade and its inner structure are designed as prefabricated-load-bearing-concrete-L-shaped-sandwich-elements. In their boniness, they incorporate the depth of the balconies and loggias of the tower.
