8 kilometres of hornbeam hedges, 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 extensive 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. And with Europe’s largest green facade, it offers an urban response to climate change. Giving back as much green as possible to the city is a task.
