A new expansion was built on the site of the previous restaurant in the northwest, which was connected directly to the Deutschhaus via an intermediate structure. On the roof of this building section is the Landtag terrace, which will continue to be accessible from the lobby. The end of the extension is slightly elevated in comparison to the intermediate building and is designed as a clear, cubic building. With its reduced formal language and moderate height, it is less conspicuous than the Deutschhaus and functions as the urban conclusion of the ensemble.
