Imagine a self-sustaining haven nestled high in the Italian Alps, a testament to innovation and a sanctuary for mountaineers. This is the vision behind CRA–Carlo Ratti Associati's groundbreaking bivouac pavilion, designed for the 2026 Milano Cortina Winter Olympics. But what makes this structure truly remarkable? Let's dive in!
CRA, in collaboration with Salone del Mobile.Milano, has unveiled plans for a digitally fabricated wooden bivouac. This isn't just any shelter; it's designed to be entirely self-sufficient. It will incorporate cutting-edge systems for energy production and storage, as well as an ingenious water harvesting system that utilizes air condensation. After its debut as an urban pavilion during the 2026 Winter Olympics in Milan, the plan is to airlift the structure by helicopter to its permanent home in the high-altitude Italian Alps, providing a crucial refuge for climbers.
The architects' primary goal? To seamlessly blend human-made structures with the natural environment. The design process began with a detailed 3D scan of existing rock formations in the Alps. This scan provided the precise model needed to inform the bivouac's unique geometry, minimizing its visual impact while maximizing its functionality. The structure will be equipped with tools for self-sufficiency, including energy production, storage, and water harvesting through air condensation.
But here's where it gets interesting: The resulting shell structure will be composed of cross-laminated timber (CLT), aerogel, and metal. It will feature a 5 kW peak photovoltaic system with energy storage, ensuring independent operation, including network connectivity. Furthermore, the shelter will use an air condensation system to produce potable water daily, providing a reliable water source for climbers and trekkers. The design embraces circular design principles, allowing the structure to function both as an urban pavilion and a durable alpine shelter.
And this is the part most people miss: The design deviates from the traditional appearance of a bivouac. Its form evokes the crystalline formations of the Alps, while its material treatment leaves the wood visibly exposed. Unlike conventional bivouacs, which are often painted in bright colors for visibility in adverse weather, this shelter adopts a more subtle appearance. It features a bright red light that activates automatically in poor visibility, enhancing safety while minimizing visual impact. A glass wall will open the interior to the surrounding Alpine landscape, offering a space for reflection, rest, and connection with nature.
Carlo Ratti, co-founder of CRA and director of the Venice Architecture Biennale 2025, emphasizes that the design aims to integrate with the natural landscape. He quotes the famous 20th-century Italian architect Gio Ponti, stating that architecture should be 'like a crystal.' CRA has embraced this concept, utilizing digital fabrication to design a bivouac that appears to be part of the natural rock formations of the Alps.
This project is one of several initiatives being prepared for the 2026 Milano Cortina Winter Olympics. CRA has also designed the event's Olympic Torches, which take a minimalist approach. Meanwhile, Skidmore, Owings & Merrill (SOM) has completed the Athletes' Village in Milan, which will serve as both a temporary residence for athletes and the largest student housing complex in Italy. The 2026 Games are set to be the most geographically widespread Winter Olympics in history, following the model established by Paris 2024 by relying almost entirely on existing and repurposed sports infrastructure. The games will take place from February 6 to 22, 2026, marking the first time the Winter Games are organized across two cities, two regions, and two autonomous provinces.
