Beiersdorf is restructuring its factory premises in Hamburg-Eimsbüttel to make the company’s headquarters fit for the future, both in terms of architecture and organisation. The concept reverses the current situation of the closed perimeter development: The new residential quarter opens up and interlocks with the adjacent urban network of the Eimsbüttel district. A large square in the centre of the residential area serves both the new residents and the neighbours from the district as a lively, urban meeting point. As an urban counterpart to the Park am Weiher, it creates identity and links the existing with the new. Green paths and differentiated courtyard layouts create a high quality of living. The size and cubature of the new buildings are based on the nearby block structures dating from the Gründerzeit period. The result is a breathing perimeter development, which is formed by the public intermediate space, opens up towards the edges and interlocks with the urban and green spaces. Based on the building type of the Hamburger Burg, the spatial expansions create varied sequences in the public space, provide insights into the depth of the residential blocks and enable good lighting conditions in the apartments.
