The new construction of an eight-storey residential and office building in a prominent location impresses with its extraordinary architecture. The changing floor plans make high demands on the static-constructive planning. The cantilevered part of the building was realised by a framework-like reinforcement with diagonal steel elements. The building is founded with a combined pile and slab foundation, the basement is designed as a white tub. The small number of stiffening elements on the ground floor required great attention in the planning of an earthquake-proof supporting structure by capacity design. By forming ductile walls, the earthquake energy is dissipated in clearly defined zones.
