 Originally intended to be the site of the Hornsby Technical College, the Department of Education later decided to build Asquith Boys on its current site instead.Construction of the school buildings began in late 1959 but it was realised that they would not be finished in time for the school's opening in 1960 and thus the half the first boys were housed in various sites around Hornsby while the other half were housed in Chatswood High School.By mid-1960, the A Block was complete and the school moved onto its present site on 24 June 1960.
