(Uberbau, 2013) Our vision for the Ruhr-Metropolis the Network City is based on the existing. It focuses on cooperation, communication and co-production. Social, economical and ecological values will be added, which will manifest in space and serve all stakeholders in the Ruhr Area.
1. The Time-City allows for an optimized everyday life of each individual: It guarantees accessibility, shorter ways, minimized trip-lengths and arranges regional and local freight transport.
2. The Field-City structures the handling of big agricultural areas and the urban carryovers of the Ruhr-Metropolis: Area-reserves of the metropolis will be farmed in a tactical way and value will be added to the areas.
3. The Sponge-City describes a productive use of the water resources: Water resources will not only be drained off, but used in a productive way for the structuring of the Ruhr-Metropolis in connection to climate change. The Economy of Sharing links the theme-cities.
36 tools will be defined for working in the theme-cities. They are characterized by decisive goals, references to the existing scalability, the ability to be multiplied and potential for integration. The connection and interlinking of the single tools serve as a base for planning and steering of a process-oriented urban development.
