Cities and regions worldwide are faced with sweeping processes of transformation: social and demographic change, digitalization, and new technologies all represent significant challenges. Many cities and regions have already demonstrated ways in which transformation processes can succeed—provided they are supported by convincing strategies. RHA Reicher Haase Assoziierte’s multi-faceted projects focus on shaping structural change at all levels from neighborhoods to regional contexts. In addition to this, the firm develops concrete strategies and concepts for making appropriate, effective use of abandoned sites and generating interest in their surrounding areas. Over twenty-five years of theory and practice, they have discovered that good urban planning is, above all, a question of finding the right combination of uses for different typologies.
