11 Dublin Avenue, Killarney Heights NSW 2087

Level block | DA-approved dual occupancy | premium family street | streamlined development path This property’s primary buying case rests on a rare combination: a flat 740sqm block in a tightly held family suburb with pre-approved plans for a five-bedroom residence plus a separate three-bedroom granny flat. For a buyer seeking a knockdown-rebuild or multi-generational setup, the approved design removes the typical six-to-twelve-month approval delay and its associated holding costs. The site’s elevation, orientation, and lack of overlay constraints reduce build risk, while the existing house remains habitable—allowing the granny flat to be built first as a live-in base or immediate rental income stream. The street’s high owner-occupier rate and proximity to top-catchment schools reinforce long-term demand, making this suited to a builder-occupier, an investor targeting dual-income yield, or a family wanting separation of spaces. The stormwater easement requires a structural engineer’s review before purchase, as it may affect excavation or foundation costs. The existing 1970s house has limited renovation value; any budget for cosmetic upgrades is better redirected toward the approved build. The price guide sits near the top of off-market estimates, so a buyer should negotiate on the basis that the DA’s value is offset by the easement risk and the need for full demolition. The suburb’s 89% long-term resident profile signals low turnover and steady capital growth, not short-term flipping potential. Hold as a build-and-hold: construct the main residence for family use, lease the granny flat to cover a portion of the mortgage, and benefit from the rising land value in a supply-constrained Northern Beaches pocket.
