The project
The Allgemeine Baugenossenschaft, Zurich (ABZ) is realizing 169 affordable modern apartments with its newly built development and at the same time rejuvenating the villa district. This is still characterized by detached houses with spacious gardens. Despite the significantly higher building density, the 13 new buildings fit in well with the existing neighborhood. The 2- to 6-1/2-room apartments offer space for families, couples, singles as well as the 55+ household community. The development meets the sustainability goals of the 2000-watt society. Timbatec Holzbauingenieure was responsible for the facade construction. The curtain wall elements made of wood are attached to the slab facades.

The construction
The supporting structure is designed as a conventional solid building in cast-in-place concrete and bricks with a few facade columns and supporting walls. These were either masonry or concrete, depending on the static loads and building physics requirements. During construction, attention was paid to extensive system separation so that components can be easily replaced according to their service life.

The challenge
Particular attention was paid to the cantilevered balconies. In some cases, they protruded up to around four meters from the facade.
