An office building grows upwards

An office building from the 1960s in the Zurich district of Hottingen has had an entire storey added. Blumer Lehmann was in charge of the timber construction and created the extension as a prefabricated timber structure.

New office spaces and four apartments with a usable floor area of 513 m2 were added to the building with the new storey. The building was extended with a prefabricated timber structure, which was placed on top of the existing concrete roof.

The facade, which was designed within heritage conservation guidelines, was made with white fibre cement panels. As a result the additional storey cannot be distinguished from the rest of the building.
