In 1982, Auer Weber defined the main features of the Starnberg District Office in its competition entry. The existing building was constructed between 1985 and 1987, and in 1989 it was awarded the German Architecture Prize. The need for employees, which has increased over the past 34 years, meant that it needed to be expanded. The concept for the extension sees it largely resembling the existing building, both externally and internally, with no break between the existing building and the extension, so that both staff and visitors feel as if they are in one building.

The district building is not a common administration building, but rather a building which due to its inviting, open and communicative nature can be interpreted as a building for the people. As a result of the interaction between the interior and exterior, the construction and the landscape, as well as the man-made and the natural elements, the object, which is protected by a generously cantilevered eaves, melts harmoniously with its surroudings. Although it does not lie directly on the lake shore, water in the form of canals and basins stretch up to the edge of the building, which was constructed using simple construction methods and a modular construction system.
