Impluvium Installation by Banco!: A Contemporary Rainwater Harvesting Pavilion Reflecting on Ecology and Water Cycles

Reimagining Rural Architecture through Rainwater Harvesting

Set within the evolving agricultural and cultural landscape of Fourneaux, France, the Impluvium Installation by Banco! stands as a minimal yet profound architectural intervention. Created as part of a public call for experimental rural design by Ferme de Vernand and the Polyculture Association, the structure is a celebration of ecological engagement, traditional wisdom, and landscape dialogue. It takes the form of a rainwater harvesting pavilion that reconnects people to the natural water cycle while highlighting freshwater as a vital, endangered resource.

A Site Rooted in Ecology and Agricultural Heritage

Located at the edge of a man-made pond of uncertain origins, the site already serves multiple ecological roles. It functions as a biodiversity habitat, an agricultural water reserve, and a local social amenity. Rather than imposing on this environment, the Impluvium acts as an interpretive lens, inviting visitors to reflect on how such modest infrastructures support the rhythms of both natural systems and human needs.

Architectural Form Echoing Ancient Practices

The Impluvium draws on the ancient Roman archetype of a roof that funnels rainwater into a central basin. This typology, reinterpreted through contemporary detailing and natural materials, enables temporary water collection, emphasizing the volume and rhythm of rainfall. The roof captures rainwater, slows its cycle, and channels it gently back to the adjacent pond. In doing so, the pavilion connects climate, landscape, and architecture in a seamless ecological gesture.

Micro-Architecture as Reflection Space

Spanning just 14 square meters, the structure’s scale encourages intimacy with the surrounding elements. Built from wood and finely crafted joinery, it shelters users while framing views of the pond and surrounding agricultural land. The modest form offers a place to sit, to pause, and to consider the temporality of water—its abundance, its absence, and its place in global environmental systems.

Water as the Architectural Narrative

At its heart, this rainwater harvesting pavilion is not only a functional object but a narrative device. It visually and experientially illustrates how water moves, collects, disappears, and returns. Through seasonal changes, the structure becomes a living barometer—each visit presenting a different quantity of captured water, reinforcing awareness of climate patterns and water scarcity.

Bridging Utility and Cultural Expression

The Impluvium is more than a technical solution for water collection. It is also an invitation to rethink how rural spaces are activated through micro-architectures that blend utility, symbolism, and education. It creates a new visual and experiential vocabulary for water stewardship—one that is grounded in local materiality and landscape rhythms, but universally resonant.

A Pavilion in Service of Agroecology and Shared Stewardship

Aligned with the park’s commitment to agroecology—practices like food autonomy, rotational grazing, and diverse cultivation—the pavilion serves as an emblem of sustainability. It complements the broader landscape strategies by introducing architecture that’s low-impact, pedagogical, and accessible to all. It represents a model of how public design can serve ecology without dominating it.

A Small Architecture with Large Implications

The Impluvium reminds us that even small, meditative structures can deliver profound ecological insights. Through its poetic form and sustainable function, Banco! has created a pavilion that serves not only as a shelter but as a subtle call to action—a space where one contemplates the value of water in every form.
