Witikonerstrasse, Zürich

The project
In Zurich's Witikon district, 2 apartment buildings with 38 apartments were built. The majority of the family apartments have 4.5 or 5.5 rooms. The simply developed apartments all have a balcony or a terrace. With the direct bus connection to the city center, Witikon has moved closer to the city center and should therefore become more attractive again for younger people. The property is located on the outskirts of the city in the immediate vicinity of woods and meadows and is nevertheless very close to the district center.

The construction
The two apartment buildings on Witikonerstrasse were constructed as a classic hybrid building with load-bearing concrete ceilings and non-load-bearing exterior walls in timber frame construction. Vertical inverted formwork in spruce/fir was used as the façade cladding. Timbatec planned and supervised the facade design including fire protection and quality assurance (QSS). The vertical partitioning of the rear ventilation was created with floor-by-floor steel aprons.

The challenge
For the construction approval of the combustible facade, discussions with the fire department and fire police had to take place at an early stage. This meant that the fire department's access routes and intervention options could be planned into the project at a very early stage and implemented in the end. Thanks to this early clarification, the project was approved without any problems, since everyone involved was already aware of it.
