In addition to classical architectural work, Jörn is also involved in the Berlin Chamber of Architects. Here, for example, he advocates more open architectural competitions. His special passion is architectural theory, the subject in which he also completed his doctorate. He writes books on “The Poetics of Building”, organizes discussion evenings and exhibitions on the beauty of architecture, on Schinkel and Mies. With his wife, who is also his office partner, he is currently planning his own house. His favourite building? Obviously the Neues Museum – poetics, aesthetics, cultural history of modernism. You can listen endlessly to the lovingly and precisely chosen words with which he talks about details. For example about what he intends to do with 150-year-old bricks.
