Immermann Tower, Office tower in Stadtmitte, Düsseldorf, Germany.

Immermann Tower is a 16-storey reinforced-concrete office high-rise on Immermannstraße in Düsseldorf-Stadtmitte, standing over 58 metres tall. Its 1987 rebuild by Rüdiger Thoma of Hentrich, Petschnigg und Partner gave it an International Style curtain-wall facade, replacing the neoclassical look of the 1954–56 Dommelhaus, which had a projecting main cornice above an attic storey.

The tower was completed in 1956 as Düsseldorf's first post-war modern high-rise and was originally called Dommelhaus. A major renovation in 1987 brought updated exterior features and resulted in the building being renamed to reflect its importance to the city.

The tower takes its name from Karl Immermann, a noted dramatist from Düsseldorf whose works shaped German theatre and literature. Today it stands as a recognizable part of the downtown landscape, visible to people passing through the central district daily.

The tower stands in a central location with easy access via public transportation, making it convenient to reach from different areas of the city. Being in the business district, the surroundings are busy during business hours but quieter in the evenings.

With 16 floors and over 58 metres, the Dommelhaus narrowly overtook the Wilhelm-Marx-Haus, which had been Düsseldorf's tallest office building until 1956. Its architect was also its owner: Wilhelm Dommel, who gave the building its original name.
