The parish hall of Langnau am Albis was built in the early 1960s. The well proportioned building has exposed brickwork walls both internally and externally and concrete ceilings.

The Social Services Department who occupy the building required more space and the only option for expansion was in the direction of the small entrance hall with a view of the rear garden.

The main concerns of the project were to ensure that the view from the entrance hall to the garden was not obstructed and that the new interventions were carried out with respect to the original building fabric. Since any changes to the exposed brickwork would have been visible, it was decided to plaster all new surfaces and elements and to marry them to the existing with a carefully coordinated colour scheme.
