Concrete meets Corten
A minimalistic new residential and office building on the edge of Landshut‘s old Gothic town centre.
The three-storey reinforced concrete building, clad with bare corten steel, houses an architectural office, another office and a apartment. In the basement there is an underground car park with 15 parking spaces. The project was completed at the end of 2017.
The building concept envisages a monolithic cubature that harmonizes with the natural surroundings of the castle mountain. The central idea was the planning of a building that is sustainable at all levels: clear design language, use of recyclable materials, avoidance of composites, use of regional building materials, reduction of energy consumption.
The entire basic building structure including a flat saddle roof in solid construction consists of reinforced concrete in exposed concrete quality. Ceilings and roofs are equipped with concrete core activation. The building shell consists of a corten steel cladding that forms patina over time and adapts to the topography. The alignment of the individual storeys follows different contour lines of the mountain and offers different perspectives on the old town of Landshut through large window fronts. The various floor plans range from closed to open spaces and the transition from inside to outside is seamless.
Greatest challenge was the handling of the existing topography of the mountain with its 70% slope inclination. In addition, the architects were confronted with large amounts of leaking slope water during the removal of the slope. This water proved to be a stroke of luck and is now used thermally for heating and cooling the building carried out by a concrete core activation system, thus supporting the sustainable building concept.
