NUN Schools Dorms for Girls and Boys are placed in Beykoz Campus of NUN. These dorms are optional for students who prefer to stay on campus. Campus dorms are designed as flats. Three or four students stay in each flat, they own their own bed, closet, study desk, and bookstand. Flats share bathroom and lavatories. Each flat is furnished with ergonomic and comfortable items, entrance to flats requires electronic cards. Premises are subject to high security measures at all times.

NUN Dorms are designed for the support of student development rather than a residential need. Boarding school has proven benefits to student development; they learn to take responsibility, time management, sharing and helping, improving social relations. In addition to these a boarding student can make use of his/her time after classes joining co-curricular activities on campus; arts and sports, clubs and workshops exclusive to NUN students. Unlike their peers who spend two hours on a typically hectic Istanbul traffic during rush hours; they spend this time in nature, busy with arts and sports continuously working on their self development and creativity. They are able to use the library and other facilities on campus until late hours.
