The challenge of Le Grand Réservoir association with the grouping of Altarea-Cogedim – TVK on the Cachan Campus project was to create links between the different crowds of the new campus, as well as to open up the old campus on the city.



The response of Le Grand Réservoir lies in the old reception building of the ENS school, designed in the concept of La Porterie, which is a central venue at the entrance of the campus. La Porterie is an area shared between residents and students, as well as between students from different schools. It allows porosity between the different campus users, and focuses on encounters, reflection, and the creation of social links.



Cachan residents and students enjoy cultural ideology, as well as an innovative and seductive area focused on slowing down and living together.
