As society changes, so do the demands of urban development - these themes are discussed using examples from all over Europe. In certain parts of the world, the founding of new towns and extensive urban development are still going ahead rapidly at the beginning of the twenty-first century. In Europe, however, which already has a high degree of urbanisation, more cautious interventions into the urban structure are required. By means of both permanent and temporary interventions, attempts are being made to meet the complex requirements of a changing modern society. The interdisciplinary cooperation of partners from different fields - such as culture, architecture, and economics - and the participation and initiatives of citizens play an important role in this. This volume pursues the question of how individual projects not only stand out within the complexity of urban structures but can also bring about long-lasting change. This book presents forty-seven European examples from the Urban Intervention Award Berlin that showed quite surprising solutions, and which received awards from the Senate Department for Urban Development and the Environment in 2010 and 2013.
