2025 In Munich’s dense Maxvorstadt, growing demand for education meets a city with little space to spare. raumBILDUNG explores how the Schwindstraße primary school can grow within its existing footprint. An extension above the gymnasium activates a previously unused roof, bringing learning clusters, shared spaces and circulation into a layered structure. The addition gives the schoolyard a new spatial edge, while wraparound galleries extend it vertically and connect the different levels. Inside, open meeting places replace the rigid organisation of the corridor school. These informal centres are framed by enclosed volumes that accommodate specific functions, leaving the surrounding space available for different ways of learning. A variable curtain system adjusts the degree of openness, allowing a shared landscape to become a series of quieter places for concentration and retreat. Along the perimeter, vertical slats filter daylight and views, forming a calm threshold between school and city. Above, the roof becomes an additional outdoor space for sport and everyday use by the school and neighbourhood. Vertical growth becomes a way to reconsider how learning, collective life and open space can coexist within the dense urban fabric.
