 In 1952 a lowset timber Boulton & Paul Building was constructed at the western end of Block B.Responding to materials shortages and the pressures of the baby boom, the DPW imported a British prefabricated building system from manufacturers Boulton & Paul Ltd of Norwich.Based on an planning and construction module, the prefabricated elements in the Boulton & Paul system included wall panels, ceiling panels, roof trusses and banks of awning windows.
