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
KDR in Concord is one of the LGA's strongest mid-tier markets — inland village stock outside HCAs covers most of the suburb. Wianamatta Shale soil; minimal rock excavation. Demolition $35K–$65K with asbestos prevalent in 50s–70s stock. Realistic premium turnkey $1.4M–$2.8M for 280–450m² build. Pre-construction 4–7 months.
On the ground in Concord (2137), the practical numbers shape every knockdown rebuild. Class M–H (Wianamatta Shale) / H (river/bay fall) soil — moderately to highly reactive clay — pushes engineered foundation work into the $24,000–$42,000 bracket on most 500–900m² blocks. R2 Low / R3 Medium / R4 (Rhodes/Concord West) zoning under City of Canada Bay Council sets the building envelope, with R3 Medium Density pockets that open up dual occupancy options on qualifying lots. Median sale price across Concord sits at $2.2M–$4M, which frames the build-versus-buy decision from the start. Nearest rail is Concord West (1 km), and that proximity affects everything from rental demand to construction site access.
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.

Why Knockdown Rebuild in Concord?
Concord is the inland heart of the LGA — Federation cottages, inter-war Tudor and Spanish Mission, post-war stock on 500–900m² blocks. Heritage Conservation Areas cover several streets. Wianamatta Shale soil. Concord Hospital and Concord Oval landmarks.
Concord sits in the City of Canada Bay local government area with 500–900m² residential blocks and R2 Low / R3 Medium / R4 (Rhodes/Concord West) zoning. Building costs are around the Sydney metro average, balancing construction value with lifestyle and growth. Transport access via Concord West (1 km) connects Concord to the wider Sydney network. 1900s–1960s-era housing stock across Concord is prime for knockdown rebuild — replacing dated layouts and materials with modern, NCC-compliant homes that maximise block potential. Ground conditions (Class M–H (Wianamatta Shale) / H (river/bay fall)) across Concord are well understood by local builders — Buildana's engineering accounts for moderately to highly reactive soil movement.
KDR in Canada Bay works inland village stock outside Heritage Conservation Areas — Concord, Five Dock, Russell Lea, Canada Bay, Wareemba and the inland portions of Mortlake and North Strathfield. Riverside heritage peninsulas (Abbotsford, Chiswick, Cabarita, parts of Drummoyne) are extension-restricted. Wianamatta Shale soil; rock excavation rare and shallow ($5K–$20K) on inland lots, deeper on sandstone-outcrop river-fall lots. Demolition $35K–$70K with asbestos prevalent in 50s–70s stock. Realistic premium turnkey $1.4M–$2.8M for 280–450m² build, peaking at $2.5M–$4.5M on river-fall premium blocks in Drummoyne and Abbotsford. Pre-construction 4–7 months.
Planning Controls — City of Canada Bay Council
Canada Bay LEP 2013 & Canada Bay DCP 2017. R2 Low Density covers most older residential streets: FSR 0.5–0.55:1, building height 8.5–9m, front setback 6–7.5m, landscaped area 35–40%. R3 Medium Density along Lyons Road, Great North Road, Concord Road and Parramatta Road permits FSR up to 0.85:1. R4 High Density and B4 Mixed Use concentrated on Rhodes peninsula (Rhodes Waterside, Concord Road towers), Concord West / North Strathfield station precincts, and Five Dock village (gearing up for Sydney Metro West 2030 — Five Dock station precinct already designated TOD). Heritage Conservation Areas cover the riverside peninsulas (Abbotsford, Chiswick, Cabarita, Mortlake, Drummoyne) plus pockets in Concord, Five Dock, Russell Lea, Wareemba, Rodd Point. Tree Preservation Order LGA-wide. Wianamatta Shale soil with sandstone outcrops on the river-fall peninsulas — fall to Parramatta River, Iron Cove, Hen and Chicken Bay, Canada Bay drives suspended slab engineering on premium river-fall lots. Five Dock Sydney Metro West (under construction, opening 2030) is the LGA's signature planning event — station-precinct overlay opens density bonuses inside 400m of Five Dock station. Rhodes peninsula has industrial-legacy soil contamination management protocols on remediated former Union Carbide site.

Building in Concord — Local Context
Site & Ground Conditions in Concord
Concord sits on Class M–H (Wianamatta Shale) / H (river/bay fall) soil — moderately to highly reactive clay. For a knockdown rebuild, that rules out the cheapest off-the-shelf slab designs straight away. and pushes engineered footings into the $24,000–$42,000 range on most 500–900m² blocks here. Geotechnical testing isn't optional — every Buildana rebuild in Concord starts with a borehole report so the slab and footings are sized to your actual block, not a generic spec. Skipping that step is how you end up with cracked cornices and sticking doors three years in. Drainage design matters too — overland flow paths on Concord's topography can collect water against rear setbacks if the contour survey is sloppy.
City of Canada Bay Planning Context
City of Canada Bay has its own LEP and DCP layered over State planning controls. For knocking down and rebuilding in Concord, the practical impact: City of Canada Bay Council's DCP sets local rules for streetscape character, materials palette in some precincts, vehicle crossover widths, and tree retention. R2 Low / R3 Medium / R4 (Rhodes/Concord West) zoning on most Concord blocks permits single dwellings, alterations, and additions. Buildana checks every overlay (heritage, bushfire, flood, acid sulfate soil, biodiversity) before quoting.
Cost vs Value in Concord
Median sale price in Concord is $2.2M–$4M. For a rebuild, the decision tree runs through three numbers: build cost, expected post-completion value, and how long you plan to hold. New custom homes in Concord re-set the property at the top of the local price band, with new-build premium of 10–20% over comparable established stock. We map this in feasibility before you commit.
Lifestyle Fit in Concord
Concord has a settled residential character. Concord West (1 km) from the nearest station. Local landmark: Concord Hospital & Concord Oval. For families knocking down and rebuilding here, the design considerations that matter day-to-day: orientation for natural light (north-facing living wherever the lot allows), separation between adult and kids' zones, a kitchen that opens to outdoor entertaining, garage size that fits a real family vehicle plus storage, and a layout that doesn't require renovating again in 10 years as the kids grow. Buildana designs for the long arc of how families actually use a home, not just the showroom photo.
City of Canada Bay Council Processing & Concord Activity
City of Canada Bay Council processes thousands of residential applications a year across the City of Canada Bay LGA, and Concord (2137) sits in the active end of that workload. For a knockdown rebuild, the realistic clock from lodgement to DA determination is 8-14 weeks. The applications that move to the front of the queue are the ones where every required document is correctly named, drawn to scale, and matched against the SEPP or LEP clause it's claiming compliance with. Buildana lodges every project at that standard — not because it's required, but because it's how you avoid sitting in the RFI loop for an extra month.
Builder's Take on Concord
Service abolishment and reinstatement in Concord typically costs $3K–$8K. Sydney Water cap-off, Endeavour Energy disconnection, gas cap. Cheap KDR quotes often bundle this into "demolition" as a line item worth $1K — which is wrong and gets billed later.
The biggest surprise on KDR for clients is how much the new house improves the suburb feel. Same street, same neighbours, same kids' schools — but the house finally fits. Concord residents who KDR rarely regret it; the ones who renovate instead often tell me they wish they'd gone the rebuild path.

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 (Wianamatta Shale) / H (river/bay fall) 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.
