Description

The residential building in Lucerne’s Seetal valley demonstrates how densification can be achieved in rural areas and beyond conventional construction concepts. The building was constructed without thermal insulation, metal or chemical building materials. The solid timber construction is glue-free, and all interior surfaces have been left untreated to ensure the reusability of the materials in line with the principles of the circular economy. The façades are clad with rough-sawn timber formwork. The floor slabs are emphasised by friezes on the façade, which also articulate the building. The friezes, windows and sun protection are – just like the other elements of the timber construction – subtly joined and can be easily dismantled. The access core is made entirely of layered, recycled tamped concrete, without reinforcing steel. The staircase rests on beams made of prefabricated elements, which are placed on the tamped lift walls. The structural principle of compressive strength works thanks to the mass of the tamped concrete, the elements and the balanced distribution of forces within the staircase. The floor plan is based on a simple, historical chambered typology. The transitions between the chambers are visible in the floor in the form of wooden thresholds – making the spatial concept and wooden construction coherent. All rooms unfold from this centre.
