Erich-Ollenhauer-Haus

The Erich-Ollenhauer-Haus is an office complex with a concrete facade in Bonn's Gronau district that features a comb-shaped layout with four parallel wings. The structure faces Ollenhauerstraße and now houses various businesses and institutions.

The structure served as the German Social Democratic Party headquarters from 1975 to 1999, replacing earlier temporary facilities. After the party's relocation, various businesses and offices were established in its spaces.

The building embodies post-war German social democracy through its modern design, reflecting how the party wanted to present itself as forward-looking. Visitors can still observe the technical precision and functional beauty of the design today, which mirrored the party's ideals.

The structure is now accessible for businesses and institutions and is located in a convenient position near central Bonn. Visitors can view the exterior facade and overall design from the street.

The brown anodized metal facade and continuous vertical glass windows create a repeating pattern along the street front. This design was a bold expression of technical modernism in 1970s German office architecture.
