Animal hospital new office building, Zürich

The project
Based on the certificate of need, the target had to be expanded from the original 500 m² to 1000 m². The new building, a three-story wooden structure, stands on piled strip footings and is air-laid. Floor box girder elements were laid over the foundations, and these were also used for the false ceiling and flat roof. The room partition walls are simple stud constructions with planking on both sides, which have to fulfill specified fire resistances according to the use and requirements.

The construction method
The exterior walls were made in stud construction. A special feature is that the building grows outwards as the number of floors increases. The building is clad with vertical plus-minus formwork with different board thicknesses. Another special feature is that the elevator shaft is also made of wood.

The challenge
With an extension of the office containers and to obtain an unlimited building permit, the following problem points arose: Fire police objections/corrections, thermal objections/corrections and electrical supply lines, which were provisional until then. All these considerations led to the construction of a new building on the site of the existing provisional one.
