A knockdown rebuild in Concord costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, City of Canada Bay Council approvals, and construction under one fixed-price contract.
Concord KDR — Single Contract, New Home
A knockdown rebuild in Concord suits the character stock on 500 to 900m² blocks — Federation cottages, inter-war Tudor and Spanish Mission, and post-war homes in the inland heart of the LGA, with Concord Hospital and Concord Oval as landmarks. A rebuild resets a dated home into a modern one in a settled, sought-after pocket.
The ground is Wianamatta Shale, so the slab is designed off a real geotech. Heritage Conservation Areas cover several streets, and on a well-kept inter-war character home the restore-versus-rebuild question is worth weighing, so I give you a straight read.
On the R3 land, a dual-occupancy can be worth costing where a block clears the 600m² minimum. The older stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility before you commit.
Buildana manages the complete knockdown rebuild process in Concord — 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.

Character stock in a settled suburb
Concord is the inland heart of the LGA, with Federation cottages, inter-war Tudor and Spanish Mission, and post-war stock on 500 to 900m² blocks, framed by Concord Hospital and Concord Oval. A rebuild resets a dated home into a modern one in a settled, sought-after pocket.
On a well-kept inter-war character home, the restore-versus-rebuild question is worth weighing, and I give you a straight read.
Shale, heritage and the duplex question
The ground is Wianamatta Shale, so the slab is designed off a real geotech. Heritage Conservation Areas cover several streets, so a listed block goes down the DA path. On the R3 land, a dual-occupancy can be worth costing where a block clears the 600m² minimum.
The older stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition.

How It Works
From First Call to Final Key
Free site inspection of your Concord property. We check lot dimensions, City of Canada Bay 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 1900s–1960s-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 M–H 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.
⏱Quality Promise
Concord knockdown rebuild done cleanly: licensed demolition, compliant slab, new home built to NCC 2025. Fixed-price contract.
