Design and construction planning for the remodelling of a private house from the 1920s in Dietikon (2013). The spatial qualities of the living area were significantly changed through opening the space to the kitchen and allowing direct access to the garden. The kitchen and bathroom were renovated completely and the floor plan of the entrance situation was optimised, in doing so, attention was paid to cost-saving solutions. Likewise all sanitary and electrical installations were renewed. It was possible to maintain the existing character of the house by dealing carefully with the building fabric.
