How can architecture engage in dialogue with the most extreme forms of nature—respecting and enhancing them at the same time? Each of the shelters studied and personally experienced by Matteo De Bellis offers a different answer to this question. An architect and photographer with a deep passion for the mountains, De Bellis has spent years researching high-altitude architecture. Throughout his work, he photographed 82 Alpine bivouacs, later selecting 32 for a more in-depth study exploring the history and architectural typologies of these small yet essential structures serving mountain hikers.
This is how the project “Minimum Living in the Alps” was born—an anthology celebrating the beauty and challenge of these refuges while exploring their deeper meaning and their role within the Alpine landscape.
“Since childhood, the mountains have been my chosen place—a space of discovery, adventure, and reflection. They’ve taught me values such as respect for nature, simplicity, and solidarity.
This profound connection has inspired my architectural and visual research, leading me to explore how architecture can engage with the most extreme natural contexts—enhancing and respecting them at once”.

As De Bellis observes, bivouacs represent the perfect synthesis between design and engineering: essential micro-architectures designed to withstand harsh weather conditions while offering shelter in remote environments. They are true works of art, where diverse yet complementary forces—functionality, aesthetics, and environmental respect—coexist in balance.
The word bivouac, derived from the French bivouac, originally referred to a temporary, minimalist camp without tents. Introduced to Italy by Napoleonic troops, the concept gained importance during World War I, when military outposts and logistics structures were built at altitudes of around 3,000 meters. From these origins emerged the first fixed alpine bivouac prototypes, initially made of wood and iron, later of sheet metal.
In the past, the bivouac was primarily conceived as an emergency refuge, a place of protection against extreme conditions. Today, it has often become the destination itself—a point of arrival that offers a unique, direct encounter with the mountain.

A bivouac is a threshold space, where the infinite vastness of the mountains meets the intimate scale of the human being. In this sense, each bivouac tells its own story—a testimony to the technological and cultural evolution of high-altitude architecture. Today, these small structures reflect a new collective awareness of the role architecture can play in such extreme natural contexts.
Discreet and harmonious, far removed from tourist consumerism or superfluous intervention, bivouacs embody an architecture stripped of ornament, embracing minimalism and essentiality as guiding principles for engaging with one of the world’s most extraordinary natural landscapes—the Alps.
"In their simplicity, bivouacs offer a precious example of sustainable design. Every detail—from the choice of materials to the organization of interior space—is conceived around a single priority: the essential. This minimalist approach, free from excess or spectacle, expresses a philosophy of respectful dialogue with nature at its most extreme".
