Reconstruction and extension of the former Kossätenhaus Berlin Wannsee at Wilhelmplatz
The former Kossätenhaus is an important part of the ensemble of Wilhelmplatz in BerlinWannsee in terms of monument preservation, the reconstruction into a residential and commercial property an impact for its appearance.
The reconstruction was of great public interest, which was expressed by the intensive support of the State Office for the Preservation of Historical Monuments. The object is integrated in the district of Stolpe and the commercial focus of Wannsee. In its location to the square, the building is integrated between the churchyard forecourt and a restaurant, so that not only the historical ensemble effect was closed, but also a further densifying addition of the commercially used objects in this area was achieved. For better perception, the object was placed slightly elevated on afeldstone base.
The building is divided into a historic, restored old building, the dimensions of which allow for modern uses, and an extension that sensibly expands the building for contemporary commercial use. The old building, which is visible from the square, corresponds to the historic appearance in terms of the materials and colors chosen and has been restored in a manner appropriate to its status as a historic monument. The extension is located on the side facing away from the square and, with its light, glassy formulation, appears as a filigree construction that does not interfere with the old building. It is adjoined by a gravel garden bordered by planking.
