2024 Urban uses are becoming shorter lived, while the spaces they occupy remain in constant transition. Pavillon Mobil explores an architecture that can move with these changes. Conceived as a temporary prototype for repeated assembly and disassembly, it is independent of a permanent site and can activate residual urban spaces through new uses. Its capacity to be relocated makes it part of an architecture of the in-between, adapting to changing social and spatial conditions. This openness continues within the structure itself. Manually operated façade panels, supported by gas struts, shift between enclosure and exposure, creating varying degrees of shelter and connection to the surroundings. Their movement allows the pavilion to respond to different activities and to the ways people occupy it. A 1.25-metre modular grid provides the underlying order. Reversible connections and a systematic arrangement of components allow the structure to be assembled efficiently, taken apart and put to use again. Design for Disassembly shapes both its construction and its architectural identity: individual parts remain legible, and the logic of joining and separating becomes part of the spatial expression. The pavilion is understood as an adaptable system, open to successive places, users and configurations, with its character emerging through construction, movement and use.
