Large block in Blackburn | school-zoned family house | flood overlay noted | suited to renovators or rebuild buyers This is a generously proportioned family house on a 925 m² block, which places it among the larger sites in Blackburn’s detached housing stock. The combination of a 254 m² building footprint, three car spaces, and zoning for Laburnum Primary and Box Hill High schools makes it a strong candidate for families who want room to spread out without moving to a smaller lot or a townhouse. The property’s form and land size also appeal to renovator-occupiers or buyers considering a rebuild, as the block offers scope that many newer infill sites in the area do not. The house itself appears functional rather than premium, but the land and location are the primary drawcards here. The flood management planning control flagged for this site may affect future redevelopment or extension plans, so a buyer should investigate what that overlay permits before forming a firm view on price. The building coverage of around 27% leaves room for additions or a new dwelling, but the overlay could limit design options or require additional engineering. The property’s value is driven heavily by land and school zoning, which supports strong demand from family buyers, but the yield from renting is likely modest given the high land component. A buyer should weigh the renovation or rebuild opportunity against the constraints of the overlay, as those factors will shape both use and resale potential.
