The new Croset-Parc middle school completes the existing educational complex within a fast-changing context—a future housing district set to replace a disused industrial site. To address this impending densification, the project adopts two compact volumes, offset both in plan and in section. By choosing a single, simple geometric figure—the rectangle—the design aligns itself with the neighbouring school buildings and with the district’s prevailing morphology of solitary parallelepipeds.
Shifting the two blocks in plan frees generous covered-play areas. The building’s form clearly expresses its programme: a four-storey main volume containing the curricular and extra-curricular spaces occupies the northern edge of the site, while a lower, downstream block houses a double sports hall. The latter is sunk into the ground so that its roof becomes the school playground. The two volumes meet at a sheltered recess, where a cantilevered upper storey forms a covered courtyard.
The sloping site allows multiple entrances. The school touches the ground on two levels. The lower ground floor opens directly onto the playground and hosts the after-school facility. The upper ground floor, entered from the street, contains PPLS (pedagogical–psychological support) rooms and one classroom wing. The sports hall has its own entrance opposite the outdoor playing field. Two stair cores stitch the stacked programmes together.
The plan is organised in three bays: classrooms open to the east and west façades, while the central hall enjoys north–south transparency thanks to the positioning of special rooms—staff room, craft/technical spaces and storage—along its length. A skylit void connects all three teaching levels.
The structure is of concrete. Two longitudinal shear walls carry vertical loads past the sports-hall roof, creating an unobstructed, column-free covered playground. The façades are assembled from prefabricated modules that combine fixed and operable glazing, an integral blind and an aluminium finishing cap.
