Located on the CIRAD Baillarguet Campus near Montpellier, the project to build a set of quarantine and pathology greenhouses is intended to provide scientists with a range of facilities enabling the production and cultivation of plants that will serve as study material under reproducible conditions requiring high levels of bioclimatic control. This complex is located in the immediate vicinity of existing laboratories and culture units and uses the fluid and energy resources already available on the site.

This facility is built as an extension of, and in connection with, the Joint Research Unit in Genetic Biology of Plant–Parasite Interactions and includes a Quarantine area (sugarcane and yam), a Pathology area (banana, coffee, cocoa, rice, yam and sugarcane), and the associated technical premises (cold room, washing zones, repotting and storage areas) grouped within a connecting building serving both the new and existing buildings.

To ensure visual continuity with the existing structure, the connecting building adopts the volume and architectural language of the adjacent building to which it is attached, and its metal cladding extends into the base of the three greenhouses. Access from the outside is via a central space marked by a white colour between the greenhouses, which are identified in green.
