The new town hall in Rosenberg stands in a valley between the incorporated villages of Bronnacker, Hirschlanden, and Sindolsheim. The new facility was designed and built with the expectation that this municipality could be incorporated into a larger township within the next twenty years. Flexibility of current use and potential re-use, were therefore paramount in the design of this structure.

A reinforced concrete ribbed slab spans the entire building width. Demountable partitions divide these support-free areas and can be easily removed or reconfigured. In the roof level is the Council Chamber, which is spanned by a double-curved timber shell. A covered loggia at this level offers a splendid view of the church facade and the valley beyond. Together with an existing school, the baroque church, and an enormous chestnut tree, the new building completes a public square that was only partially evident before the start of construction.
