As part of the NSW Government's public schools upgrade program, Hutchies has been awarded the contract to perform infrastructure improvements at William Stimson and two other schools. Works will include a new two story 'homebase' building and a single story support unit facility fitted with state-of-the-art disabled support equipment, fixtures and fittings. The new buildings will provide 12 new permanent classrooms, and four support unit classrooms and will provide space for up to 620 students.

The support unit will be 1100m² in size and will be constructed of lightweight prefinished panel on a suspended slab on piers. The homebase will be 2,996m² and will feature timber ceilings and an external architectural powder-coated louvre system. The scope also includes landscaping and softfall playground areas.
