Thomas Robert Gladwin from within the Department of Public Works. It copied the architectural details from the original section. In order to make room for the extension, the playshed was relocated on the site further south, adjacent to the western boundary. In 1952 the Oslo Lunch Room was converted for domestic science lessons. The verandah was enclosed with vertical timber boards and glass louvre windows to form a teacher's room and fitting room and a laundry. Casement windows with operable fanlights were added to the eastern gable end wall and high-level glass louvres were added to the west gable end wall. New doors and built-in sinks and joinery were added. In 1964 the Oslo Lunch Room was converted for use as a tuckshop. In 1955 two allotments fronting Ruthven Street (part of the original school site sold in 1906) were acquired and incorporated into the school grounds. Here, an infants' wing was constructed in two stages between 1957 and 1959 and opened by the Minister for Education, Jack Pizzey, in October 1959. The building was a standard design by architects within the Department of Public Works. It was a long and narrow two-storey building with open play space and one classroom on the ground level and classrooms on the upper level accessed by a verandah along the northern side. It was a brick, timber and concrete structure with a timber-framed gable roof. It had banks of timber- framed awning windows on the southern elevation, providing a high level of natural light and ventilation to the classrooms. It was connected to the western end of the main building via a ground-level covered walkway. This walkway was reconfigured in 1962 to be two storeys and include toilets, a staff room, a health services room and a store room. In March 1960 a plaque mounted on the new infants' wing was unveiled by Director of Primary Education, Arch Guymer. It dedicated the wing to recently retired Aileen Wadley, who taught at Toowoomba South Girls' and Infants' State School from 1 January 1938 to 31 December 1959. The building was called the "Wadley Wing". In 1977 the verandah was enclosed with aluminium-framed sliding windows and a ground-floor extension accommodating a janitor's room was added to the southern side of the wing in 1979. Alterations were made to the first floor of the main building in 1960. This included removing a folding partition and inserting
