urbainable - stadthaltig. Positions on the European City for the 21st Century ISBN 978-3-88331-241-5 (English edition). The European city has been an engine of civilisation since its creation. Today, however, fundamental challenges such as climate change mean it is facing changes that cast doubt on the continuity and sustainability of the ethical foundations of urban life. On the basis of projects, visions and manifestos, the members of the Architecture Section and their guests from all over Europe present their positions for a new direction.
