State School 4727 opened on Belmore Road in 1954, on a site bounded by McColl Road, Sewell Street and Milne Road. Enrolments reached 355 by 1959 but had declined significantly by the early 1990s. This led to a ‘merger’ with Box Hill North Primary and Box Hill Primary at the end of 1993. The result of a ‘quality provision task force’ decision, it meant consolidation on the Box Hill North site, and closure for the other two schools. The Koonung Heights site was sold ($2,064,000) to make way for the Scarborough Square housing estate.
New townhouses started appearing in Sewell Street by 1995.
