<P> The four House dormitories have secret entrances , generally known only to members of that house and require a password ( Gryffindor & Slytherin ) , riddle answer ( Ravenclaw ) or ritual ( Hufflepuff ) in order to gain entrance . Inside is the common room , which contains armchairs and sofas for the pupils and tables for studying and homework . There are fireplaces to keep the rooms warm , and students either relax here in the evenings or else complete their homework , but may complete their work in the bedroom . There are notice boards in each common room and at other strategic points throughout the school . The students sleep in their House dormitories , which branch off from the common rooms . Each dormitory gets at least two rooms ; one for boys and one for girls ( an enchantment prevents boys from entering the girls ' area , although there is no spell to prevent the reverse from occurring ) . Each student sleeps in a large four - poster bed with bed covers and heavy curtains in the House colours , and thick white pillows . There is a bedside table for each bed , and each dormitory has a jug of water and goblets on a tray . </P>
