Haus des Deutschen Metallarbeiterverbandes

This is an office building for a labor union in Kreuzberg with a triangular form, curved facade, and horizontal window bands reflecting modernist design. A taller central section connects two side wings and creates the building's distinctive shape.

This headquarters opened in 1930 for a metalworkers union and served the labor movement. After the political shift in 1933, Nazi authorities seized it and the building suffered significant damage during World War II.

The building reflects the New Objectivity movement through its clean lines and functional steel and stone details. Visitors can still observe this distinctive design language in the horizontal window bands and minimal ornamentation.

The building sits on Alte Jakobstraße in an accessible part of Kreuzberg and currently houses union district management offices. The location is easy to reach by public transport and the architecture is visible from the street.

A bronze spiral staircase in the entrance area leads to an elevated floor with a conference hall behind large glass windows. This striking staircase was technically advanced and allowed an efficient layout for the labor movement.
