Supporting growth: In 2008, just a few years after sop | architekten completed the new headquarters building in Cologne’s Kämmergasse for DEG (Deutsche Investitions- und Entwicklungsgesellschaft), part of the KfW Development Bank, its bankers were already running short of space. Sop | architekten then went on to win the design competition for the construction of an annex building with its plan to create an entire DEG Campus.
As a result the project involves both a new extension building on Agrippastraße and its connection via a tunnel to the building on Kämmergasse and various conversion and development works on the existing building. In architectonic terms, the new construction will be a light-flooded, five-storey building crowned by the striking ‘Skybox’, an almost playful element. Together with the adjoining planted roof terrace, this glass office space covering some 200m2 forms a link to the existing building. The choice of the glass and metal façade also helps to make an optical connection between the two buildings, thereby creating a real campus feel.
