The new sections complement the figure of the typical Berlin block with front, side and rear wings. Several side and back wings inside the block are being demolished and replaced by an access building that links the three-wing section in Taubenstrasse and Jägerstrasse functionally. The north, stone courtyard is closed by a new section in Glinkastrasse, though an entrance is left open on the ground floor, while the larger, south courtyard remains open from the third floor and is designed as a garden courtyard. So despite block perimeter development the quarter is open within the urban space, and it will be possible to see into the block from the street. The new buildings are clad throughout in light sandstone, but their window patterns differ. An inviting visitor centre on the ground floor of the new building with public cafeteria and free access to the library and to the conference and training rooms signals the ministry's openness and close relationship with the people.
