Superblocks between theory and practice: insights from an international e-Delphi process and urban living labs in Vienna and Berlin

The concept of Superblocks has been recognized as a promising urban transformational intervention. With the concept evolving, spreading, and being adapted to different contexts, it is necessary to take stock of the situation. The article aims to clarify the Superblocks concept through an e-Delphi process and test the theoretical framework against ongoing implementations in Vienna and Berlin. Experts’ opinions show that the concept has retained transformational capacity. In practice, however, we can observe conceptual ambiguity and slow implementation, subjugated to political constraints. The article discusses how these discrepancies might affect the ability of Superblocks to contribute to systemic transitions.
