A knockdown rebuild in Elanora Heights is a premium elevated project above Narrabeen Lagoon — 1960s to 1990s brick and contemporary on 600 to 1,200m² blocks, with lagoon and ocean views from the eastern fall. The views are worth designing for, and the aging stock rarely used them.
BAL-19 to Flame Zone applies on the bushland-fringe lots backing the lagoon catchment and Garigal, so the RFS assessment shapes those designs. The sandstone means deep rock excavation of $50,000 to $130,000 is typical, priced from a geotech bore.
The older homes can carry asbestos, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the bushfire and rock costed, before you commit.
Buildana manages the complete knockdown rebuild process in Elanora Heights — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

Views worth designing for
Elanora Heights sits elevated above Narrabeen Lagoon with lagoon and ocean views from the eastern fall — views the aging 1960s-90s stock rarely used. A rebuild on 600 to 1,200m² blocks designs a substantial home around the outlook.
The elevation and the greenery make it one of the peninsula's quietly premium pockets.

How It Works
From First Call to Final Key
KDR starts with an honest look at the existing house. Sometimes it's worth keeping. Most Elanora Heights homes from the 1960s–1990s + premium contemporary — especially fibro and brick-veneer — are beyond the point where renovation makes sense. We tell you straight.
⏱Demolition is pre-approved to run parallel with rebuild design. Asbestos cleared, services abolished, site stripped in a single mobilisation. Geotech reconfirms Class Hawkesbury Sandstone soil with the old house gone.
⏱New house goes up on the same footprint or a better one, whichever serves the block. Modern NCC envelope, better orientation, fit-for-purpose room sizes. The suburb stays the same; the house finally fits it.
⏱Final handover: new OC, six-year structural warranty, all the documentation on your Elanora Heights block you'd get on a greenfield build. The only difference is you still live in the street you chose.
