The building is designed using traditional brick and tile externally to make it part of the 'family' of existing buildings.

Internally it provides a 600-seat auditorium designed to be switched easily between the acoustics required for speech and music. The auditorium is provided with a full theatrical lighting and sound installation together with additional lighting for school assembly use. The large stage is served by a theatre workshop, costume store and generous backstage areas which double as drama teaching areas and a 130-seat, fully flexible, studio theatre. There is also a drama library, an office for the head of drama, a box office and a double-height entrance foyer.

To supplement the main auditorium, there is an informal 'small performance space' capable of seating 70 and intended for choir rehearsals and impromptu lunchtime concerts, recitals, poetry readings, etc.
