Extra storey, Neue Bahnhofstrasse in Muttenz

An additional floor was added to an office building in Muttenz. The existing large terrace was also enclosed with prefabricated timber modules. The flat roof made from fully insulated box-beam modules bonded together maximised the room height. The façade cladding was adapted to match the existing eternit cladding. The new floor features a seamless transition from the existing building, making it hard to tell it’s an extension.
