Offices and laboratories complex, Paris-Saclay campus

On the edge of the Moulon district, the building is located on a very long site facing the 18 metro line. The building is divided into four volumes, creating garden courtyards that encourage views and a central atrium where the various users can meet. The complex is topped by a largely transparent base that houses common services and contributes to the vibrancy of the public space. The upper floors are home to a variety of actors - start-ups, scale-ups, public or private companies of different sizes - made possible by the reversibility of the floors into offices or laboratories. The design of the façade follows the internal grid, combining prefabricated concrete bands, wooden transoms and limestone trumeaux from the Paris Basin, whose profiles adapt to the orientation of the building. Finally, the exterior landscaping is inspired by local landscapes and the hydrographic network, while remaining part of the green fabric of the neighborhood. To the east, a large wooded forecourt opens up to the public realm and the metro. This flood-prone garden is home to an alder grove, a true piece of nature that evolves freely with the rains. In addition to the garden courtyards, a biosolar roof covers all the volumes.
