Cheminée Commune reimagines the apothecary as the center of a civic network for medicinal cultivation, research, and production in Ervy-le-Châtel, France.
In this project, Gillian Hause (MArch II ’26) proposes a passage of architectural interventions connecting medicinal cultivation, research, production, and exchange across the village landscape. Developed in STU 1302 (Fall 2025), taught by Liu Yichun, the project draws from medieval systems of herbal knowledge and communal craft.
Cheminée Commune proposes a medieval passage of alchemical pilgrimage through the meandering rural landscape of Ervy-le-Châtel. The project looks to the apothecary as a precursor to the industrialized pharmaceutical industry, revitalizing a dormant program. Small-scale architectural prototypes engage the existing gardens to support a renewed system of medicinal cultivation, research, and production. This architectural pilgrimage journeys from the medieval garden in the town center toward its final destination at the commercial apothecary. The programs encountered along this passage are tied to medieval ways of life and include an herb bath, alchemical workshop, exhibition hall, researcher housing, roadside hearths, and commercial apothecary. Scientific trial and new methods of medicinal cultivation animate these spaces.
The Merchant Hall is the largest structure within the village. Conceived as a reflection of the medieval guild hall, the civic space allows researchers and herbologists to showcase their craft and production. The twiggy, merchant-stall column recalls the casual and makeshift nature of medieval stalls traditionally used to sell goods, serving as both structure and furniture. These individual columns notch into a larger system of roof beams, producing a field of habitation in which every column becomes a small exhibition station.
Each structure houses its medieval essence of life, forming a larger circuit of medicinal craft and production. Cheminée Commune is a contemporary guild for herbal knowledge: from the medieval potager to the modern apothecary. The incubator binds the garden, the laboratory, and the storefront into a civic metabolism of wellness.
