Opened in Spring 2005, the Octagon is situated at the centre of the School.

OctagonA dramatic eight-sided structure, it has transformed the landscape and identity of the School by giving the site a new heart and focus. The School invested £4.5 million in the building and succeeded in its aim of providing a multi-purpose space for teaching, receptions, performances, conferences and conventions.

OctagonSituated in the school's central courtyard, is designed as a focal point for school activities. It provides either clear open space for teaching, rehearsal and examinations or, through the operation of electronically controlled banks of seating and staging, a fully-equipped 600-seat performance space.

When the theatre layout is in use, lighting, projection and sound are monitored from a control room overlooking the stage. The building is self-contained with front and back-of-house facilities for visitors and performers.

All parts of the School make use of the Octagon; Westbourne performs its Christmas production there each year, Prep girls use it for drama workshops, concerts and the annual disco and Senior girls attend Assembly there 3 times a week and have timetabled classes plus extra curricular activity inside.

The Octagon's self-contained design has brought another benefit to School life; during public examinations the space becomes the main examination area allowing complete silence and distance from the main School building and minimum interruption to the rest of School life
