Kearns Mancini's proposal for the Highcastle Public School sought to incorporate and renovate an existing two-storey west wing of over-sized classrooms into a more efficient space, while also adding an additional building with new classrooms and communal spaces. The buildings are sensitively connected through a central, glazed corridor, which defines a new courtyard framed by the existing and proposed building.
The original program for Highcastle Public School was to provide an 11 classroom, 4 kindergarten room addition, while at the same time removing 6 portable classrooms. Following a series of user group meetings, the final program was expanded to renovate an existing two-storey west wing of oversized classrooms to allow for a more efficient space usage, adding classrooms, upgrading the mechanical systems and developing a senior students arts and science technical suite. Ultimately, the addtion and re-management of these programs was meant to foster a larger school population and increased availability to educational resources.
