Apartment house Sommergasse 7, Allschwil

Addition of a floor to a residential building in timber element construction

The apartment building at Sommergasse 7 in Allschwil, built in 1954, was completely renovated and topped up.

The design called for the existing gable roof to be removed and the building to be raised with a new attic in timber construction. Roof loads are transferred from rafters to a ridge, two center purlins and the knee walls. There are four dormers on each side of the roof so that the new attic can accommodate two separate living units.
