Designed as a hybrid timber-concrete structure, the tower uses prefabricated elements to shorten construction time. Concrete is used for staircases, basement floors, and ceilings, while load-bearing pillars, down-stand beams, and the façade are made from locally sourced beech wood, processed in Switzerland. This approach reduces the building’s carbon footprint by around 20%, saving an estimated 670 tons of CO2 over its 60-year life cycle.

Project Status

Most flats are now complete. The metal façade with integrated horizontal photovoltaic panels has been installed, scaffolding removed, and trass-lime cladding at the base is being finalised. Landscaping is underway. Full completion and handover are scheduled for the end of May 2025, with residents expected to begin moving in from August.

The jury appreciated several notable aspects of this residential project. They particularly admired the remarkable integration of the building within the urban context and the meaningful dialogue it establishes with the surrounding public space. The thoughtful material selection was also acknowledged, noting the balanced and harmonious combination of timber structural elements with other materials, such as concrete, clay and trass lime. This deliberate choice showcased a commitment to sustainability while adding to the building’s aesthetic appeal.

The sleek and elegant architecture garnered high praise, as it can serve as a source of inspiration not only for low-tech, residential buildings within the Swiss context but also beyond. Overall, the jury appreciated how the design embodied sophistication and innovation, potentially influencing sustainable architectural practices on a broader scale.
