Narraweena might be the purest knockdown rebuild suburb on the Northern Beaches, 1950s to 1970s brick on 500 to 750m² blocks, no beachfront hazard zones, no heritage drama, just post-war housing that is done its job and land worth $2.0M to $2.8M underneath it. The KDR market here is strong for exactly that reason: owners are not fighting overlays, they are just replacing a spent house.
Sandstone is the one line item to respect, rock excavation runs $40K to $90K on typical lots, and the topography means some blocks need more cutting than the neighbour's. Cromer Park and the public school anchor a quiet family pocket that people genuinely do not want to leave, which is the whole argument for rebuilding over relocating. Get the geotech done, get the excavation priced, and the rest is straightforward.
What I would check first on a Narraweena block: the sandstone rock cost from a geotech, the land value against the tired house, and the cutting the topography needs. Those set the budget.
We build these fixed-price, licence HBL 487805C. We will handle all three, so start with a site visit.
Buildana manages the complete knockdown rebuild process in Narraweena — 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.

How It Works
From First Call to Final Key
Free site inspection of your Narraweena property. We check lot dimensions, Northern Beaches Council's planning controls, existing home condition, and potential asbestos. Written assessment with budget estimate within 5 business days.
⏱KDR is the chance to get the design right — the new build doesn't have to mimic the original layout. We start from your block's strengths (orientation, slope, views) and your family's brief, then design the home the original lot always deserved.
⏱Licensed demolition of existing 1950s–1970s-era dwelling. Asbestos removal by certified contractors (if present). Site cleared, levelled, and ready for new slab. Typically 1–2 weeks.
⏱Your new home goes up on the cleared site. Engineered slab sized for Class Hawkesbury Sandstone soil, frame, roof, fit-out, kitchen, bathrooms, flooring, painting, driveway, and landscaping. Quality inspections at every stage.
⏱Handover pack: OC, structural certificates, BASIX, appliance manuals and warranties, paint colour schedule, maintenance plan, and the keys. Six-year structural warranty kicks in from OC date — keep the documentation safe for any future sale.
