As was the case with the primary schools, standard post-primary school plans were prepared to meet the great increase in the school population in the period immediately following the Second World War. The first, known as the Naenae type school, was a two-storey building, of reinforced concrete construction up to first floor level and timber frame above, with the teaching rooms in long rows and with access from corridors at both levels. This was the first school fully planned as a complete entity with the incorporation of specialist facilities for the full range of subjects in the modern curriculum. It proved, however, slow and costly in construction for the large buildings programme looming ahead and was replaced by the Henderson type school of similar content but in single storey timber construction.
