The Bauhaus Building is almost 100 years old. Besides, it is a UNESCO World Heritage Site. Accordingly, it must be permanently maintained and regularly renovated. Also at present, the Bauhaus Building is being restored inside and outside. We try to keep the restrictions for visitors to a minimum. However, they cannot be completely avoided; but maybe you will see it as an opportunity: it is rare to see so vividly what it means to preserve a World Heritage Site.
The plaster on the base of the Bauhaus Building and also on the facade of the south staircase is being renewed. After the old plaster has been chipped off, new plaster will be applied. It is a special plaster containing parts of mica which indeed lets the Bauhaus Building shine in a special way.
Restoration of windows
A few of the windows in the Bauhaus Building date back to the time when it was built. This is also the case in the souterrain. All the windows there are currently being repaired and repainted. This will result in temporary restrictions for visitors in the area of the Archaeology of Modernism exhibition.
The metal sheets at the edges of the roof – the so-called attic sheets – are being renewed. The attic is the extension of the outer wall and connects with the flat roof. The flashings cover the upper edge of the outer wall and protect it from the weather. In addition, they are the top layer to prevent water from penetrating the roof structure.
In some of the guest rooms in the studio building, the historic stone-wood screed is being repaired. These floors, which are now almost 100 years old, require renovation and subsequent maintenance in order to preserve this material for future generations. Especially cracks are visible to everybody. They visually disturb the homogeneity of the surface and can also lead to massive lasting damage to the material. Moisture can penetrate the screed and decompose its structure which can lead to considerable loss of material and thus substance. Now, after preparatory work, these cracks are filled with colour-matched material and thus sealed, so that further penetration of moisture and material destruction are prevented.
With the help of the scaffolding on the studio building, crack monitors have been attached to the west facade. Over the course of one year, these monitors, in conjunction with weather data from the German Meteorological Service, will provide information about the relationship between climatic conditions and crack behaviour.
