A knockdown rebuild in Strathfield costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Strathfield Council approvals, and construction under one fixed-price contract.
Strathfield KDR — Single Contract, New Home
Nowhere in the inner west scrutinises demolition harder than Strathfield, and any honest conversation about a knockdown rebuild starts there. Heritage Conservation Areas cover virtually all the older streets of the Federation-mansion estate, and heritage assessment is the first step before KDR or duplex feasibility even opens. The 700 to 1,500m² blocks that make this suburb magnificent are exactly why Council guards it.
Outside the protected fabric, and pockets do exist, the fundamentals are elite: $3.0M to $5.5M heritage-estate medians, Wianamatta Shale soil that behaves, and land depth that supports genuinely grand homes. Strathfield's 650m² duplex minimum is higher than most LGAs, another reason single premium rebuilds dominate. Spending on design before confirming heritage status is the most expensive mistake made here.
What I would check first on a Strathfield block: whether it sits inside an HCA, the heritage contribution of the existing home, and the Wianamatta Shale soil. Those decide feasibility.
We build these fixed-price, licence HBL 487805C. Confirm status first, we will manage the assessment and tell you plainly what your block allows.
Buildana manages the complete knockdown rebuild process in Strathfield — 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 Strathfield property. We check lot dimensions, Strathfield 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 1900s–1940s Federation mansion/Californian Bungalow heritage + inter-war Tudor + 2010s+ R3/R4 redevelopment around Strathfield/Homebush stations-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.
