The Buys Ballot Building has both tutorial rooms and several computer learning rooms. The classrooms are mainly located on the ground floor, the first floor and the second floor.
The building does not have a freely accessible entrance. Access without an access pass is possible via the first floor of the Koningsberger building. The main entrance of the Koningsberger building is on the Budapestlaan. From the entrance, go diagonally right between the reception desk and the stairs. Then go through the door into the hallway. The elevators are located further on in the corridor on the right. On the first floor, exit the elevator and turn right. After the doors, turn right again and continue straight on until you see the automatic doors of the Buys Ballot building. The elevators of the Buys Ballot building are located in the middle of the building. So, after the automatic doors, go straight on to be able to use them.
