The architectural scene in Germany has several regional centers, but since reunification it has also certainly focused on Berlin. In the capital, world-class architecture can be experienced at close quarters: Whether Lord Norman Foster, who converted the former Reichstag building into the new German parliament, Renzo Piano, Daniel Libeskind, I. M. Pei or Rem Koolhaas – the list of international architects who have made their mark on the face of Berlin in the 21st century is long. Vice versa, German architecture companies such as von Gerkan, Marg und Partner and Albert Speer & Partner also enjoy international success. Sustainable building, in other words architecture which consumes as little as possible or even no energy at all, is playing an ever greater role. This is a topic which architects from Germany such as Stefan Behnisch, Christoph Ingenhoven, Werner Sobek and the duo Louisa Hutton and Matthias Sauerbruch addressed early on, and in which they have acquired expertsie that is in demand worldwide. Also attracting attention is Graft, a trio of architects from Berlin that combines the avant-garde and ecology – as in the futuristic project “Bird Island“, which is under construction in Malaysia.
