Deutzer Hafen is an old industrial habour area in Cologne, located south of the city center. The project transforms the former harbour into a lively and sustainable neighbourhood with a huge waterfall and public swimming pool as a new landmark. The pool collects rainwater and waste heat from the district, solving a serious problem of flooding from the Rhine River, while simultaneously creating a new unique attraction in the city. The project consists of new housing typologies integrated among the industrial cultural heritage preserved on the site, providing homes for 5,000 inhabitants and workspaces for another 4,500. In addition, a new bicycle bridge over the Rhine River connects the neighbourhood directly to Cologne’s city centre.
