这座典型的1970年代的建筑坐落在山坡上，可以看到康斯坦茨湖和Reichenau岛的壮丽景色，但它急需根据目前的能源标准进行改造。新的业主和开发商托马斯-坦纳从其强大而粗糙的形式中看到了潜力，让人联想到这个时期的建筑。从可持续发展的角度来看，大量的灰色能源已经融入到现有的结构中，这说明了修复而不是拆除。
Nestled in its hillside location with breathtaking views over Lake Constance and Reichenau Island, this typical 1970’s building was in desperate need of rehabilitation regarding current energy standards. The new owner and developer Thomas Tanner saw potential in its strong and rough form, reminiscent of architecture during this time. From a sustainability perspective, the large amount of grey energy already built into the existing structure speaks for rehabilitation rather than demolition.
它向湖边倾斜的长方形主体建立在一个坚实的基础上，创造了一个强大的动态，使这个建筑具有了自己的特点。这种倾斜的姿态被保持下来，并通过仔细地重新设计窗户尺寸以形成水平的窗条来加强。原有的湖边立面被清空，整齐地暴露出其大胆倾斜的木质双梁，支撑着巨大的悬空体。
Its lake-ward tilting rectangular body rests on a solid base creating a strong dynamic that gives this building its character. This sloping gesture was maintained and enhanced by carefully reworking the window sizes to form horizontal window strips. The pre-existing lakeside facade was gutted out, neatly exposing its bold slanting wooden double beams that support the large overhanging body.
一个精致的黑色金属栏杆在这个扩展的外部生活区中呈现出湖水和它的观察者之间的唯一屏障。取而代之的是一个井盖，屋顶现在围绕着整个山丘折叠，面向建筑背面的立面。建筑物东面和西面的横向立面用垂直的木板进行了装饰。
A fine black metal railing presents the only barrier between the lake and its beholder in this extended outside living area. Replaced with a welleternit cover, the roof now folds around the entire hill facing the facade on the backside of the building. The lateral facades to the east and west of the building are cladded with vertical timber planks.
能源修复项目的艺术在于保护建筑的质量和特色。萨伦斯坦的房子通过形成成熟的特征、形式和功能实现了这一点。该建筑的外壳现在完全绝缘，旧的燃油加热被替换为节能的热泵。通过勤奋的细节设计，我们实现了将一栋有50年历史的建筑和谐地转变为具有现代标准的持久的家庭住宅，否则它将不得不被摧毁和处理。
The art of an energy rehabilitation project is to preserve the architectural quality and character of a building. The house of Salenstein achieves this by forming a mature character, form, and function. The shell of the building is now completely insulated and the old oil-fired heating replaced with an energy-efficient heat pump. Through diligent detailing, we achieved the harmonic transition of a 50-year-old building into a lasting family home with modern standards, which would have otherwise had to be destroyed and disposed of.
