A knockdown rebuild in Killara costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Ku-ring-gai Council approvals, and construction under one fixed-price contract.
Knockdown Rebuild Builder in Killara
We will not sugar-coat knockdown rebuild in Killara: the heritage streets between the Pacific Highway and the Lane Cove valley escarpment are lined with inter-war homes Council actively protects, and demolition applications on contributory houses face genuine resistance. Blocks are magnificent, 800 to 1,400m², deeper than the typical Ku-ring-gai lot, which is precisely why owners keep asking. The answer depends entirely on your specific house and its heritage status.
Where a dwelling is not heritage-listed or contributory, a rebuild on that much land near Killara station is one of the north shore's best plays, $3.0M to $4.5M medians say the value supports serious architecture. Soil grades M on the ridge and tips toward H on the valley fall, so siting affects footings. Duplexes need 1,200m², ruling most blocks out.
What I would check first on a Killara block: the heritage status of the specific house, the soil where the land falls, and whether serious architecture is warranted. Those decide it.
We build these fixed-price, licence HBL 487805C. Commission the heritage and feasibility check before the design dollars, we will line both up for you.
Buildana manages the complete knockdown rebuild process in Killara — 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 Killara property. We check lot dimensions, Ku-ring-gai Council's planning controls, existing home condition, and potential asbestos.
⏱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 1920s–1960s (heavy heritage stock)-era dwelling. Asbestos removal by certified contractors (if present).
⏱Your new home goes up on the cleared site. Engineered slab sized for Class M soil, frame, roof, fit-out, kitchen, bathrooms, flooring, painting, driveway, and landscaping.
⏱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.
