The design of the new Technical Administration Building of the municipality of Düsseldorf by AllesWirdGut together with Hertl.Architekten rests on the foundation of a permeable plinth and articulates the large built volume required in the competition brief as a slender tower of four interlocked tall blocks. A cleft in this building part—kept deliberately low in relation to the surrounding houses—marks the park-side main entrance. Intensive planting on the facades and the plinth-area rooftops invites passing through, and lingering in, the little urban oasis.
