The house made of spruce is a renovation with a partial replacement building. The original house was built in two stages. The basement was built before the Second World War. It was, in corresponding prosperity, designed for a large house and solidly built. The upper floors, the wooden structure, had to be built after the end of the war, much smaller and simpler than intended. Due to the poor structure of the wooden building, the decision was made to build a replacement building in the upper floors and to renovate the basement. The new building takes over the internal structure and load transfer of the original building and, due to urban planning requirements, also the external volume.
