Project description

At Saumackerstrasse 76-80 in Zurich, the existing building was renovated, the roof truss was demolished and a new attic floor (prefabricated timber construction) with six apartments was added. The apartments on the standard floors were renovated in occupied condition and had to be worked on in stages in short periods of time.


Special features

During the execution of the construction works all apartments were occupied. The main task was the demolition of the solid construction elements in the attic area - a special challenge for contractors and residents A special concern of the client was to upgrade the terraced multi-family house to Minergie standard. The relocation of the exposed element staircases proved to be a structural challenge, as no breakthroughs into the apartments were allowed and the existing ceiling was an hourglass ceiling. With screw connections, drillings accurate to the millimeter and subsequent concreting of the support components, the installation was made possible - to everyone's satisfaction.
