Transformation of a Pigsty in Chavornay by Madeleine architectes + Studio François Nantermod

Once a modest pigsty nestled between a farm and a henhouse in the rural village of Chavornay, Switzerland, this agricultural building has been transformed into a refined residential and professional retreat. Designed by Madeleine architectes in collaboration with Studio François Nantermod, the project demonstrates the power of adaptive reuse in architecture, breathing new life into a forgotten structure while preserving its rural character.

From Pigsty to Contemporary Home

The project, spanning 150 m², reinvents the existing volume to serve the dual purpose of a private parental retreat and a professional workspace. The ground floor now accommodates a liberal profession, while the upper level is reimagined as a residential haven for the parents of a large family. This transformation maintains a strong dialogue with the surrounding context: to the east, the picturesque orchard offers a serene morning atmosphere, while to the west, the setting sun bathes the barn roofs in warm twilight hues, echoing the romantic landscapes of Caspar David Friedrich.

Spatial Circulation and Design

A pair of wooden helicoidal staircases act as vertical connectors, creating a sculptural circulation core that emphasizes verticality while separating professional and private functions. The entrance sequence follows a winding path through tall grasses, culminating in a wooden footbridge — a vernacular detail deeply rooted in Swiss rural architecture. This element completes the architectural promenade, blending practicality with a poetic sense of arrival.

Materiality and Sustainability

The renovation embraces a sustainable material palette, combining mineral and vegetal elements for both insulation and aesthetics. An innovative mixture of lime and hemp forms a breathable insulating layer, applied directly onto the old facade. This “new skin” was crafted in a participatory workshop involving the architects, craftsmen, and clients, reinforcing the building’s authenticity and community-driven spirit. The resulting facade treatment feels raw, honest, and deeply connected to the site’s agrarian heritage.

Architecture of Continuity

Rather than erasing the past, the project celebrates continuity. By retaining the rural essence of the original pigsty and enhancing it with modern spatial strategies, the transformation creates a meaningful balance between heritage and contemporary living. The architecture embodies values of reuse, sustainability, and contextual sensitivity, offering a model for future rural revitalization projects.
