During the rebuilding works staff and pupils were temporarily based at Woodside School, close to the city's Anderston area.

The new building was completed in 2003[2] and the school was officially opened on 3 December 2004 by the then Education convener of Glasgow City Council, Steven Purcell, a former pupil.

In 2007 the school produced a version of Romeo and Juliet which received national media attention as it brought to life issues relating to sectarianism.
