In 1904, the girls' school moved into the present accommodation on the west side of Harrogate.
[2] In 1907 the school acquired a panel by sculptor Frances Darlington, depicting Sir Perceval's Vision of the Holy Grail which was fixed above the fireplace in the reading room.
Additional extensions that housed a library, a science block and a gymnasium were built later in the 1950s.
Later, more buildings were constructed (a sports hall in the 1980s, an art room, and the Highfield Prep School).
Currently, the grounds, playing field, tennis courts, houses and gardens occupy about 28 acres (11 ha) of the Duchy Estate.
Each house is overseen by a housemistress and full-time residential staff who look after boarders during after-school hours.
