Given the pluralization of lifestyles and the associated needs for diverse forms of living, working, and life, successful real estate project development of mixed-use neighborhoods is essential. Andreas Wieland examines the planning and development processes that can lead to the creation of a successful and valuable neighborhood. The analysis is based on four intensive case studies of recently realized neighborhood developments in the cities of Berlin, Hamburg, Munich, and Stuttgart. The insights gained highlight the often very complex constellations and interrelations of the respective project developments and provide a wealth of experiential knowledge.
