云杉木屋是一个改造项目，替换了部分原有建筑。原房屋分两个阶段建造。底层建于二战前，本计划建成大房子，并且建得十分坚固。上层是木结构，被迫在战后完成建造，它比预期要小得多、也简单得多。由于木建筑结构薄弱，设计师最终决定替换上层并改造底层。新建筑延续了原来的内部结构和荷载构成，并根据城市规划要求保留了原有的外部体量。

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 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.

该项目在原有建筑品质的基础上进行改造，重新设计了深色立面、轻型窗框和红色护窗。建筑内部也得到相应的设计，表面覆盖大量木材，比起住宅更像是高山小屋。

Formally, the building is based on the qualities of the existing building. The dark façade, the light window frames and the red shutters are reinterpreted. The interior, which was clad with a lot of wood in the existing building and was more reminiscent of an alpine hut than a residential house, is translated accordingly.
