The listed Appendix Altes Klöpperhaus, built in 1911 as an extension of the Altes Klöpperhaus, required a new idea. After successful persuasion efforts at the monument authority, it was raised by two floors during the refurbishment and a six-storey glass tower was erected on an adjoining lot of 129 m2. The challenge: To combine all three parts of the building, in a very confined space, into a harmonious overall picture while following the requirements of monument conservation and statics. Eventually, the roof of the existing building was stripped down to the cornice and two storeys were added in line with the façade below.

Dark metal panels confidently outline the extension, creating a transition to the cool glass façade that dynamically encompasses the rounded contours of the adjacent new building. The project is striking not only for its loft-like rooms with a ceiling height of four metres but also for the spectacular panoramic views offered by its floor-to-ceiling glass façade. On the site of the Görttwiete, there are two overlapping urban ground plans, which is interesting from an urban planning point of view. On the one hand, there is the Görttwiete itself as a historically grown path, part of the old town layout of Hamburg.

On the other hand, there is the Willy-Brandt-Straße as a post-war heritage, built for a traffic-friendly city. Today, the Görttwiete comes back to life: the historical connection as a pedestrian alliance between Rödingsmarkt and Hopfenmarkt is preserved. Thus, Görttwiete serves not only as an example of urban repair but as a bridge leading to the eventful chapters of Hamburg's history.
