Regenerative urbanism rejects additional land take and works within the existing city: it strengthens microclimate, water cycles, and biodiversity through precise, spatially effective inter ventions—not by designating new quarters. In the face of the climate crisis, resource scarcity, and planetary boundaries, urbanism shifts from a growth-oriented discipline to a transformative practice of sufficiency. In this studio, existing buildings are retained, upgraded, and adapted—functionally and climatically; openspaces are de-sealed, shaded, made water-retentive, and evolved into co-habitats that consider more-than-human actors. The project area is the Gerichtsviertel with a spatial focuson the museum campus of the Museum of Nature and Mankind, its outdoor grounds, and interfaces to the Schlossgarten as well as the water bodies (Hausbäke/Mühlenhunte). Here we will develop in-situ transformation processes that deliver climate adaptation and mitigation, conserve resources, enable short material and energy loops, and create shared ecologies between human and non-human actors. We address the following questions how can the museum campus be organized as a sponge oasis to dampen heat and manage cloudbursts while achieving net de-sealing? Which low-tech levers measurably improve the microclimate? How are biodiversity stepping-stones and co-habitats (layered vegetation, deadwood, nesting/roosting offers, riparian biotopes) linked with path and water corridors—
and how does this integrate into the Klimaoasen network? How can existing buildings be retrofit technically and functionally, and how can operations (care and water management) be organized so that mitigation and adaptation reinforce one another? We work across scales—
from spatial strategy to building and landscape details—supported by mapping (heat, imperviousness, paths, biotope connectivity), axonometric system diagrams, and model making. Projects are developed in teams of three and in cooperation with the Museum of Nature and Man kind.
