The Belser family's detached house in Füllinsdorf is a combined concrete and prefabricated timber structure. The two lower floors are of a concrete design, while the top floor is a prefabricated timber construction. The house complies with the Minergie standard. The façade cladding consists of pre-greyed horizontal timber formwork with open joints. Some of the concrete walls are also clad with timber formwork, which creates an attractive combination of concrete and wood. The large projecting roof helps provide the façade cladding with better protection against the elements.
