Hall 9 is a former precast concrete factory set to be transformed into Roskilde Festival’s new creative workspace. The project’s premise is not only to reuse the existing building but also to ensure that a large proportion of the new additions are constructed from reclaimed materials sourced from other sites. Our proposal is based on the direct reuse of concrete structures from demolished buildings across Denmark. We are captivated by the idea that a factory once producing CO₂-emitting concrete elements can be transformed into a factory for ideas and innovative reuse—one that, both technically and aesthetically, can inspire a construction industry in transition.
Our proposal adheres to the existing building at every scale. Its repetition and logic form the framework for all new spatial interventions and materials. Two core structures divide the building into three main functions: an event hall, a workspace, and a workshop. These spaces can interweave in multiple ways, allowing special events to take place across all functions. Furthermore, the new spaces can extend into the surrounding public buildings, urban areas, and courtyards, fostering synergies with the district’s creative community.
The entrance is marked by an incision spanning an entire bay of the building, creating an axis aligned with a future passage to the neighboring museum. This incision exposes the original hall in its rawest state, from which the architecture becomes increasingly refined as one moves further inside. Concrete is envisioned for reuse in various ways, with considerations for availability, properties, and aesthetics guiding its application throughout the building. In some areas, concrete elements are directly reclaimed from the structure itself or from other demolished buildings, while in others, concrete is reworked to create entirely new expressions and compositions. Functionally and aesthetically, the concrete is complemented by biogenic materials, which—like the reclaimed concrete—point towards future construction methodologies.
We propose that the ribbed slabs, which must be removed from the roof during the hall’s transformation, be repurposed as the new façade material. The ribbed slabs and the existing façade elements will then function like two curtains that open and close according to functional needs, creating glimpses and filtering between different historical layers. Our proposal primarily represents a methodological approach—one where the architecture emerges from the inherent potential of the given materials, but just as much from their limitations. Our proposal is therefore primarily a conceptual and inspirational catalog rather than a fully developed solution.
