Stephan-Heinzel-Haus, Cultural heritage monument in Schreventeich, Germany

The Stephan-Heinzel-Haus is a heritage monument in Schreventeich featuring a brick facade, concrete framework, and horizontal window bands running across its south side at Wilhelmplatz. The structure extends approximately 105 meters in length.

The Stephan-Heinzel-Haus was built at the end of the 1920s as Kiel's employment office, planned by Willy Hahn and Rudolf Schroeder, and was listed as a monument in 1979. It was the first employment office in Germany designed entirely around its functions, with movable revolving doors at every entrance to stop slamming and drafts, long entrance areas instead of intermediate stairs, and relocatable partition walls in the officials' rooms. The building cost 780,000 Reichsmarks as planned. Since 1991 it has borne the name of the Kiel SPD politician Stephan Heinzel.

The building is named after Stephan Heinzel, a 19th-century politician who championed workers' rights in Kiel. This naming reflects his importance to the city's labor movement.

The building now serves as the Social Services Office for Kiel's city administration with spacious entry areas and well-planned emergency exits. The wide corridors and logical layout make it easy to navigate through different sections.

The entrances used leicht verschiebbare Drehtüren — sliding revolving doors, not turnstiles — to stop doors from slamming and to keep out drafts. The building was also Germany's first employment office designed entirely around its functions: movable partition walls in the clerks' rooms could be rearranged as public demand for job placement grew.
