ArchitectureThe typical Engadine farmhouse has its own character and all changes have to be submitted to it. With such an object, sustainability has more to do with maintaining - instead of changing. All the necessary renovation work was carried out by local suppliers using regional materials. The original elements of the house have been preserved throughout. House edges, archways and window surrounds are decorated with "graffiti", the small window niches are open to the outside like funnels to let out as little heat as possible and still let in as much light as possible. The not very smooth vaulted ceilings are whitewashed and old furniture and wooden elements do the rest to underline the unique charm of the Chesa Wazzau. Nevertheless, the house is now perfectly insulated to conserve resources and equipped with all modern amenities. A few modern pieces of furniture only emphasize the otherwise very authentic and wood-stamped basic mood. Where the peasant family, servants, maids and cattle used to live under one roof, several bedrooms and shared dreams now offer space for up to 12 people.

EnvironmentThe municipality of Bever, where Chesa Wazzau is located, was awarded the Nature Conservation Prize by the Swiss Confederation for nature conservation in 1985. The Küenzi family is also involved in landscape protection in an association to preserve the beauty and uniqueness of the Upper Engadine lake landscape as well as protection against excessive immissions of all kinds and against excessive use of the lake landscape and the adjacent riparian zones. Of course, this includes the most consistent possible waste separation and recycling, in which the guests of the holiday home should also participate.
