The project, second-place winner in the architectural competition for the Hauts de Dorigny school complex, proposes an innovative solution to accommodate 240 primary school students, an after-school structure, and a daycare center. The building, conceived as an "inhabited canopy," integrates harmoniously into its wooded environment while creating a strong architectural identity. Its distinctive form combines an "L"-shaped base and a two-level cloister upper structure. The functional layout distributes spaces between the lower level (sports and after-school activities), the ground floor (daycare and common areas), and the upper floor (classrooms). The project emphasizes connection with nature, offering covered playgrounds and a central courtyard open to the neighborhood. Flexibility of use and diversity of spaces are prioritized, allowing adaptation to evolving needs.

The project proposes an innovative and sustainable structure, designed to adapt to future needs while minimizing its environmental impact. The main structure consists of steel frames, spaced 6.40 m apart, with spans ranging from 9.6 to 16 m. This configuration, supported by tie rods at the base, ensures lightness and flexibility to the building.

This design allows for future adaptation to the evolving needs of the neighborhood, with steel being fully recyclable and the structure dimensioned for possible extensions. Interior floors use prefabricated mixed wood and low-carbon concrete slabs, ensuring thermal and acoustic comfort. Recycled concrete is limited to buried parts, minimizing its environmental impact.

The building's bioclimatic approach favors connection with nature and the use of natural materials. The orientation optimizes sunlight exposure, while the "canopy" shape creates shaded areas. Large openings ensure efficient natural lighting and ventilation.

The green roof helps reduce heat islands and increases biodiversity. The project prioritizes bio-based materials, especially locally sourced COBS-certified wood, for floors and interior partitions. The heating system combines geothermal probes and a heat pump, with distribution through underfloor heating. Photovoltaic panels on the roof complement the sustainable energy approach. The envelope, insulated with bio-based materials and equipped with triple glazing, limits excessive solar gain. A double-flow ventilation system ensures indoor air quality while minimizing energy losses.

This project thus stands out for its comprehensive approach to sustainable development, integrating innovative solutions in terms of structure, materials, and energy performance, while creating a quality environment for its future users.
