Ludwig-Erhard-Haus, Office building in Charlottenburg, Germany.
Ludwig-Erhard-Haus is an office building in Berlin distinguished by 15 steel arches of varying sizes that create an undulating ribcage-like structure running the full length of the facade. Inside, full-height atria span all office levels, and natural ventilation flows through the open promenades that connect different work areas.
The building opened in 1997 and took its name from Ludwig Erhard, West German Chancellor from 1963 to 1966. Its completion marked a shift in how large office complexes integrate natural light and air movement into their design.
The building serves as headquarters for Germany's Chamber of Commerce and business federation, making it a working center where economic decisions affecting the country are made daily. Visitors can see how modern office design supports collaborative business spaces on multiple floors.
Entry points are positioned at street level for straightforward access, and visitors can walk through the ground floor to view the interior layout. The open promenades allow easy movement between levels without relying on enclosed corridors.
The steel arches are not merely decorative but function as the primary structural supports that allow the entire building to stand without interior columns. Many visitors overlook that this flowing curved form solves a practical engineering challenge while creating an unmistakable silhouette.
