CRA–Carlo Ratti Associati, in collaboration with Salone del Mobile.Milano, has revealed the design of a digitally fabricated alpine bivouac that unites design innovation with environmental sensitivity. Designed ahead of the 2026 Winter Olympics in Milan, the project shows how advanced fabrication can produce self-sufficient architecture that blends seamlessly with its surroundings.
The project begins with a 3D scan of Alpine rock formations, which guides the shape of the structure. This process allows the design to merge naturally with the mountain landscape while reducing its visual footprint. The shell will be built from cross-laminated timber (CLT), combined with aerogel insulation and metal details, taking cues from the crystalline geometry of the Alps.
For architects and product designers, the project highlights how digital design tools can enable site-specific, environmentally responsive forms. It also demonstrates the versatility of wood and composite materials as sustainable, high-performance solutions.
Sustainability lies at the heart of the design. A 5kW photovoltaic system will power the bivouac and stores enough energy for lighting and communication. Because there are no nearby water sources, the shelter will produce drinking water through air condensation, generating several litres per day. This approach offers insight into off-grid building systems that combine autonomy and resilience.
Unlike traditional brightly coloured shelters, this one is designed to blend in with its surroundings. A red emergency light activates only during fog or low visibility. As a result, the structure maintains a low environmental impact while ensuring user safety.
The bivouac’s lifecycle reflects circular thinking. It will first appear as an urban pavilion during the 2026 Olympics, celebrating Alpine culture and design. After the event, it will be airlifted to a permanent site in the Alps, transforming from an exhibition piece into a lasting refuge for mountaineers. This mobile concept illustrates how modular design can extend both the use and meaning of a structure.
According to architect Carlo Ratti, the goal was to create a structure that adapts to its environment rather than dominates it. The result is a harmonious fusion of digital innovation and natural context, offering a vision of architecture that listens to nature.
