Sustainability is a mission: Eight kilometers of hornbeam hedges for a supergreen®-project. Over 30,000 plants – Europe’s largest green facade. The facade is an essential element of the Kö-Bogen II commercial and office building. The ensemble marks the conclusion of an urban renewal project in the heart of Düsseldorf. It also represents a paradigm shift: from an urban perspective, it signals a departure from the automotive era and a turn towards people-oriented planning. With Europe’s largest green facade, it offers an urban response to climate change and creating a new green heart in Düsseldorf’s inner city.

Today, where an elevated motorway once dominated the landscape, the Hofgarten has moved back into the heart of the city. Kö-Bogen’s sloping green facades face one another in a composition inspired by Land Art. The new building complex oscillates in a deliberate indeterminacy between city and park. The two structures form a dynamic entrance to Gustaf-Gründgens-Platz, which opens up the view to icons of post-war modernism – the clear austerity of the Dreischeibenhaus (1960) and the buoyant lightness of the Schauspielhaus (1970). Kö-Bogen II is a contemporary response to these two historic landmarks, without competing with them.
