On the occasion of the 100th anniversary of „Great Berlin“, the ideas competition „Berlin-Brandenburg 2070” was organized. The key objective was not to create a completely different, new metropolitan region on top of the existing one, but rather to further develop the existing metropolitan region based on its special features, strengths and characteristics. The respective metropolitan region has ideal conditions for the future, but these must be recognised, maintained and developed further. The contribution builds on the existing structure of the „settlement star“ and the ring line of the city and expands it to the metropolitan area. The region is perceived as a continuous urban landscape with productive centers that are well connected through the metropolitan and green ring and the water metro.
