Residential Tower Hirzenbach
best architects 18 in Gold
Zurich / Switzerland
The new apartment tower and the one-storey commercial building formally represent the existing urban typology of low-lying public functions and high-rising housing blocks. However, the unique interior spatial organisation of the apartments, which is expressed in the façade, sets this building apart from its modernist urban environment.
The 12-storey building height presented the potential for a spatial concept to be generated through its section: The targeted mix of typologies – from two-storey duplex apartments, requiring a definitive structural grid, to single-storey lofts seeking structural flexibility – led to the choice of a spanning plate structural system. The bridge-like structural solution fulfils the varied spatial requirements of the apartment typologies and makes them legible on the façade. The duplex apartments are distinguished by the inclusion of double-height spaces and a floor layout that encompasses the full building depth. In contrast, the loft apartments celebrate the idea of open space. Here, sliding walls and functional cores are the room-dividing elements. The enveloping balconies carved out of the building volume visually extend the interior out into the surrounding landscape.
