The Stuttgart office "umschichten" develops artistic and design practices to explore the relationship between urban identity and the interaction spaces of various social and cultural groups. They utilize temporary architectures and installations in public spaces for this purpose. As practicing and researching architects, they discover and collect materials that have not previously been considered as building materials, layering them into peculiar structures. Moreover, they ensure that everything they build can be dismantled and that all materials can be reused, favoring connections that can be easily dissolved at any time. "A, (B), C = A. The umschichten principle" makes the temporary and experimental nature of their work comprehensible and condenses the ephemeral installations of the office into overarching debates, such as careful resource management.
