It is a single storey building with a low-pitched gabled roof, constructed in the same materials as the original buildings. The gymnasium has highlight windows to the west, and a first-floor mezzanine viewing area to the east. The performing arts hall is located to the east of the gymnasium, and smaller associated rooms are located to the north-east.
