Contents

There were 2 buildings which made up the school, Lower and Upper buildings. The Lower building catered for 11-13 year olds and the Upper building for 14-18 year olds and included the Sixth Form. The upper building was demolished in the mid 1990s to make way for a new housing development and the Lower building was remodelled to accommodate the whole school into one building.
