The 96 meter high-rise is located on Limmatstrasse in Zürich’s former/old Industriequartier. It occupies two empty plots – forming an L-shape parcel with addresses from two perpendicular streets.
The five story high base respects the height of the surrounding buildings. As the building rises the volume gradually steps back from the streets, resulting in a simple plastic figure with diverse typologies of floorplans. The deep base and middle part offers a variety of flexible platforms suitable for offices, gastronomy, recreation or other cultural activities; some platforms have access to roof terraces, others are generous in height. The tower, from the 19th floor and upwards, provides open ground floors for diverse apartments with an opportunity of individual organization of each platform.
The high-rise has, in opposition to the conventional tower, neither a central core nor load-bearing columns in the facade. Its structural system has been reduced to a series of vertical shafts distributed systematically within the building – freeing up the center, leaving it open and transparent and making the structure flexible to changes in the building envelope.
Each elevator serves only a predefined program or a specific part of the building. This optimizes the circulation and prevents encounters on upper floors between visitors, workers and inhabitants. The system forces everyone that moves between programs/floors to pass through the huge lobby – giving it the characteristics of an open urban plaza where people pass through, from one place to another.
