From 1861–1863, the school moved to its current location on Skene Street. A large granite building in Scottish baronial style was constructed and officially opened on 23 October 1863. This allowed expansion of the curriculum to include English, mathematics, modern languages, art and gymnastics. Other buildings and extensions have been added to the 1863 building since it was built. These include the Bennum Building (originally a primary school) and the 1960s modern design: a west-wing science block, theatre, and a dining hall.
