Apartment Buildings Wehntalerstrasse

Zurich, since 2024

The loosely built-up «Ville Verte» of the post-war period is undergoing major changes under the pressure of structural densification. In the past, the relationship to the neighbours and the street could be regulated with plenty of distance, but today a more decisive, «curated» relationship is required. Instead of hiding behind hedges, the ground floor is now more approachable and accommodates work and leisure uses. In the garden, a canopied pergola forms a place for informal encounters and makes an attractive offer to shift activities away from the residents' gardens to the edge of the property. 

Wehntalerstrasse forms the backbone of the transport network from Irchel to Affoltern. It remains an important mode of transport. The address «Wehntalerstrasse» will therefore also mean living near noise in the future. This is why, along the street side, one now sees apartments that are partially sealed off – apartments that could actually profit from the morning sun and a view of the avenue trees. A design better suited to the location could not only benefit the residents but also contribute to revitalizing the public space, for example in the form of pedestrian traffic. The imposing backdrop of trees on the quiet side, away from the street, remains more idyllic, however. Every flat of the project shares in the privilege of this garden side. This is where neighbourly life takes place, where room-sized loggias compensate for the noise exposure on the opposite side.
