Central point
Clubs and societies, the "student board" (Grand Cercle) and the SUAPS (university sports department) have their offices here. The "maison" is a lively meeting point, where you may run into the Chess club training for the next tournament, the Rock club working on its dance routines or bands practicing for their next gig.
Melting pot
The "House" is on the campus, right in the midst of the Engineering Schools. The student house cafeteria is student-run and open all day and is lively meeting place. Students like to hang out here between classes, eating, playing cards or catching some rays on the terrace.
