The Circular Time Lab at Lucerne University of Applied Sciences and Arts brings together theory and practice, design and craftsmanship, teaching and urban development. It is an interdisciplinary project of the Competence Centre Typology & Planning in Architecture and the architecture degree programme at HSLU. Together with students from timber construction companies in the region, the students develop structures that are not only architecturally appealing but also fully reusable.
The focus is on learning and designing together. The students gain an insight into manual processes and technical possibilities, while the trainees participate in design processes. The result is a deep understanding of resource-conserving construction that closes cycles and preserves material value.
Experience architecture – in the centre of Lucerne
Since June 2025, the results of this collaboration can be experienced at two central locations in the canton of Lucerne, on the Inseli near the railway station and at the Viscosi site in Emmenbrücke. There, airy wooden structures with colourful fabrics invite you to linger, observe and pause. They offer protection from the sun and rain and at the same time inspire reflection.
The structures are more than just aesthetic interventions in the urban space. They are built statements in favour of a building culture that takes responsibility. Their open design invites people to engage in dialogue and makes sustainability visible and tangible. The “Lucerne Summer” thus becomes a field of experimentation for an architecture that aims for impact rather than permanence.
Circularity instead of deconstruction
Reuse is at the centre of the Circular Time Lab. The wooden pavilions are not designed as one-off buildings, but as temporary structures with a future. Existing timber components were used for the initial construction. All connections are detachable and all dimensions are retained. The pavilion will be dismantled in autumn 2025 and a new pavilion with a new function will be built from the same elements in 2026.
This iterative approach not only conserves resources, but also trains planning thinking. After all, circular construction requires creativity and precision. How does an old beam fit into a new design? How do you create beauty without waste? These questions accompany the participants of the Circular Time Lab throughout the entire process and strengthen their skills for the sustainable construction of tomorrow.
Part of an international network
The Lucerne project is embedded in the European research programme BAUHALPS, Building Circular in the Alps. in this programme, 13 partner institutions from six countries are jointly developing new strategies for circular construction in the Alpine region. The Circular Time Lab serves as a living real-world laboratory. A place for experimentation, exchange and applied research.
The cooperation not only opens up new perspectives for students and trainees, but also international networks. In this way, a local timber construction project becomes a building block for transnational change, an impulse that radiates far beyond Lucerne.
The future begins on a small scale
The timber structures of the Lucerne Summer may seem small at first glance. But they harbour big ideas: collaboration, circular economy, education and responsibility. The Circular Time Lab shows how sustainable construction can be anchored in education and made visible in public spaces. Because if you want to reuse materials, you first have to rethink ideas.
