 Boulton & Paul Buildings were timber-framed and clad, had a verandah as circulation, and a gable roof.Ideally, they were orientated so the verandah faced north and the classroom faced south but were also added as extensions to existing buildings regardless of orientation.The building could be high or low-set and had extensive areas of timber-framed awning windows, providing more glazing than had ever been used in Queensland classrooms; almost the entirety of the verandah wall and the opposite classroom wall were glazed, providing excellent natural ventilation and lighting.
