Kontorhaus Stubbenhuk, Office building from 1920s in Neustadt, Hamburg, Germany

Kontorhaus Stubbenhuk is a seven-story office building from the 1920s in Hamburg's Neustadt with a brick exterior and decorative masonry details. The windows are arranged in segmental arches, especially at ground level, and the structure stands out for its clear form and solid construction.

The building was constructed between 1923 and 1925 under architect Wilhelm Lemm's direction as headquarters for the Hamburg Grain Elevator Company in the commercial harbor district. It represents an early example of modern office design that combined reinforced concrete structure with functional interior spaces.

The building is known as the Getreideheberhaus after its builder, the Getreideheber GmbH, a grain-elevator company. Above the main entrance a glass painting by Paul Wolde, executed by glazier John Nickelsen, shows floating grain elevators at work in the harbour, with the initials "GHG" below. The blue information plaque at the entrance misspells the designer as Paul Wrode.

The building now houses the Henri Nannen School for Journalists, supported by major German publishing companies. Visitors should know that the space functions primarily as a working facility, so access may be limited for tours.

The building uses a reinforced concrete frame that allowed interior spaces to be reconfigured flexibly, while concrete pillars created a clear external structure. This was an innovative solution that met the needs of modern office buildings in the 1920s.
