SSB's boarding school is housed in Château d´Argenteuil, an old castle with modern facilities on the school’s campus.

The castle is also used for the school’s cultural activities, as well as for the school restaurant. There are single and double guest student´s rooms on two floors, a kitchen, a laundry room and large living rooms for watching TV studying or just gathering with your friends.

All rooms in the castle are connected to the school’s network, as well as the internet. In the basement there is a power-training room and outside on the school campus, there is a sports hall, which offers many different sport opportunities.
