This is similar in colour and texture to the original traditional Headington stone. The building housing the auditorium consists of an open octagon leading into a gallery cum reception area, followed by a short passage leading into the auditorium proper. On the left hand side of the passage there is a small bar while on the right there is a cloakroom. Beyond, steps lead down on either side to male and female toilets. The stage area is set at the same level as the forward row of seats.
All seats contain a small retractable writing tablet.
A projection booth at the back of the Auditorium is equipped with 35 and 16 mm cine projectors, two 35 mm slide projectors and a video projector which can also project computer generated images. Ethernet connections are provided on the stage for connection to lap-tops and thence projection of the screen image. A high quality sound system is fitted and this can be augmented by additional loudspeakers. Considerable attention has been paid to the acoustic standards of the Auditorium and voice amplification is only needed for special circumstances, for example, to provide induction loop amplification for those equipped with an appropriate hearing aid. A Steinway grand piano is located in a small room to one side of the stage.
