Girardethaus, Publishing house architectural monument on Königsallee, Düsseldorf, Germany.

The Girardethaus is a monumental corner building at Königsallee 27–31, at the junction with Trinkausstraße, in Düsseldorf. Its street fronts dissolve into a window architecture punctuated by continuous piers, and the facades are clad in light gray Bavarian Muschelkalk. The figurative sculpture was carved by Düsseldorf sculptor Albert Pehle, the ornamental work by sculptor H. Stader.

The Girardethaus was built from autumn 1905 to spring 1909 to designs by Hermann vom Endt for the Girardet-Verlag, the publisher of the Düsseldorfer Nachrichten under Paul Girardet. From 1908 to 1913 the wing on the former Grabenstraße housed the Königliches Amtsgericht Düsseldorf. The building has been a protected monument since 1984, and in 2023 the last remaining local editorial office of the Düsseldorf Express moved out.

The building shows the design language of reform architecture with baroque elements that were common in Germany around 1900. This mix of bold form and decorative details shapes how the street looks and feels today.

The building is now a modern business center with offices and meeting spaces, so it is accessible from the outside. Visitors can view the facade and entrance area with its decorative details, but should be aware that the interior is private space.

The Girardethaus was long altered over the decades, yet it has been a protected monument since 1984. In 2023 the last remaining local editorial office of the Düsseldorf Express moved out of the building. The former newspaper publisher's house now holds galleries, boutiques and coworking spaces on roughly 3,000 square metres.
