Across its 7.3 km², Glenbrook is highly constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay, and 80% is flagged bushfire-prone. There are 46 heritage-listed sites on record, and the dominant land-use zone is Environmental Conservation. The median lot measures about 954 m² across 2,037 parcels. These figures are suburb-wide - the overlays that actually apply to a given lot can differ block to block, which is what a property-level check tells you.
