IBAS Thalwil campus is located at Gewerbestrasse 14 in Thalwil, occupying 2 floors of the Pfiffner Building.
The campus has 3 lounges where students can study and work on their projects, or have group discussion while relaxing. There are two lecture rooms for classes running simultaneously, one has projector for presentations so students can easily follow along with the online class so cameras are setup. The other lecture room when vacant can be used by the students to study or group sessions. Teachers can use it too when they are conducting tests or group activities.
Near the two lecture rooms is the Administration office that is ready to welcome the students and to assist students with any school issues or merely consulting about living in Switzerland.
