Our Lady of the Assumption Catholic Primary School is a new K-6 school for 420 students in North Strathfield. The design is a realisation of the school’s vision of creating spaces that invite imagination, innovation and support independent learning and student wellbeing. The project reuses a rundown 1970s three storey former Telstra training centre that was a typical institutional example of brutalist concrete architecture of its time. Flexible, open and inviting learning spaces support the school’s vision. To maximise daylight penetration and enable natural ventilation, the external concrete façade of the existing building was replaced by high performance timber framed double glazing.
