MFH Obere Asp, Zürich

The project
The building geometry of this residential building was dictated by the neighboring building, which continued to be used intact and gave this building its basic structure. Between the old building and the new one, the new staircase was created, which rises over the entire height and is accessed by a light steel staircase.

The Swedish stoves in each apartment give the apartments a cozy charm. The two attic apartments are designed as maisonettes and have a gallery, which ends in the overheight front part flooded with light.

The construction
From the ceiling slab above the underground garage, four floors were built in timber construction. The encapsulated cross-laminated timber panels separate the stairwell from the residential section. The load-bearing wall made of cross-laminated timber runs through the middle of the building directly under the ridge and both transfers the vertical loads and serves as bracing. The exterior walls are load-bearing stud wall construction. All interior walls are lightweight walls and support the bracing in the transverse direction.

The challenge
The gallery in the attic was set back in both directions. Likewise, the building is to receive a full-surface glass area on the gable end for the incidence of light as well as the view. It was a challenge to implement these two points statically so that it would also function technically.
