A knockdown rebuild in Wentworth Point costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, City of Parramatta Council approvals, and construction under one fixed-price contract.
Wentworth Point KDR — Single Contract, New Home
KDR in Wentworth Point is not applicable — master-planned R4 waterfront apartment peninsula on remediated former industrial site, no detached stock. Apartment redevelopment only.
Practical realities of knocking down and rebuilding in Wentworth Point: Nearest rail is Olympic Park (T7, 1.5 km) / ferry to Circular Quay, which influences site access during construction (deliveries, cranage, skip placement). N/A (apartment-led precinct) blocks usually have enough room for proper site set-up, but tight battle-axe lots and narrow frontages need staging plans factored into the build program. City of Parramatta Council processes a steady volume of residential applications — clean documentation moves fast, and Buildana lodges everything at full standard the first time. Class M (Wianamatta Shale predominant) / Class P/E (alluvial Parramatta River corridor: Rydalmere, Ermington, Sydney Olympic Park, Wentworth Point) / industrial-legacy contamination overlays on Camellia, Rosehill, Silverwater fringe and Sydney Olympic Park soil (extremely reactive clay) sets foundation cost in the $45,000–$80,000 range; budget allocation for that line item is fixed in your contract, not estimated.
Buildana manages the complete knockdown rebuild process in Wentworth Point — 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 Wentworth Point?
Wentworth Point is the master-planned waterfront residential precinct on the former Homebush Bay industrial site — R4 high-rise apartment towers built 2010s onwards on 300–500m² strata blocks. No detached stock. Wianamatta Shale and reclaimed alluvial soil. Heavy industrial-legacy contamination management on remediated parcels. Bennelong Bridge and ferry to the CBD.
As one of Western Sydney's newer residential areas, Wentworth Point offers contemporary streetscapes with modern infrastructure. N/A (apartment-led precinct) lots with R2 Low / R3 Medium (station precincts) / R4 High (Parramatta CBD, Westmead, Harris Park, Wentworth Point, Sydney Olympic Park, Telopea, Epping town centre) zoning. Transport access via Olympic Park (T7, 1.5 km) / ferry to Circular Quay connects Wentworth Point to the wider Sydney network. 2010s+ apartment towers-era housing stock across Wentworth Point is prime for knockdown rebuild — replacing dated layouts and materials with modern, NCC-compliant homes that maximise block potential. Soil conditions in Wentworth Point (Class M (Wianamatta Shale predominant) / Class P/E (alluvial Parramatta River corridor: Rydalmere, Ermington, Sydney Olympic Park, Wentworth Point) / industrial-legacy contamination overlays on Camellia, Rosehill, Silverwater fringe and Sydney Olympic Park, extremely reactive) are factored into every Buildana foundation design.
KDR in the City of Parramatta is split sharply by suburb tier. The acreage-style premium tier — Oatlands (700–1,200m² R2 lots, top-school King's School premium), Carlingford (600–900m² R2), Northmead and North Parramatta (550–800m² R2) — carries premium custom KDR with end values $2.0M–$3.5M+ on Oatlands. Mid-tier KDR is the dominant scope across Dundas, Dundas Valley, Ermington, Rydalmere, Old Toongabbie, parts of Carlingford and Northmead with 1950s–1970s brick stock on 500–800m² R2 lots being replaced with two-storey contemporary builds. KDR is largely impractical on the apartment-led R4 cores (Parramatta CBD, Westmead, Harris Park, Sydney Olympic Park, Wentworth Point, Telopea Renewal Precinct, Epping town centre) where the playbook is apartment redevelopment. Wianamatta Shale soil predominant on suburban cores with minimal rock excavation; Class P/E alluvial soil with elevated water table on the Parramatta River corridor (Rydalmere, Ermington, parts of Telopea, Sydney Olympic Park, Wentworth Point) requiring suspended slabs, Class P/E footings and dewatering — cost premium $40K–$80K above standard. Industrial-legacy contamination clearance required on Sydney Olympic Park (former Homebush Bay industrial/Union Carbide), Wentworth Point (former industrial), Camellia (former Shell Oil refinery), Rosehill industrial fringe, Rydalmere (former industrial), Ermington (former Department of Defence, Boys Town) parcels — NSW EPA SEPP 55 site investigation, remediation action plan and validation reports add 4–8 months and $30K–$150K+ depending on contamination level. Heritage Conservation Areas restrict KDR on the heritage core (Parramatta CBD heritage precinct, Harris Park UNESCO buffer, North Parramatta Cumberland Hospital state-significant precinct, Federation streets in Dundas, Dundas Valley, parts of Carlingford, Epping village, Oatlands, Northmead, Rydalmere riverfront). UNESCO Old Government House World Heritage buffer-zone controls extend to adjoining streets in Harris Park, Parramatta CBD, North Parramatta and parts of Westmead. Tree Preservation Order LGA-wide. Demolition $30K–$60K with asbestos universal pre-1990. Riparian setbacks 10–60m on Parramatta River, Toongabbie Creek, Duck River and tributaries. Foreshore Building Line restrictions on direct waterfront in Wentworth Point, Sydney Olympic Park, Rydalmere, Ermington. Realistic premium turnkey $1.4M–$2.5M for 280–450m² build on suburban-core R2; $2.0M–$3.8M on Oatlands/Carlingford/Northmead premium suburban; $2.5M–$5M on direct river-frontage Rydalmere/Ermington with foreshore consent and Class P/E engineering. Pre-construction 4–7 months suburban-core; 6–10 months on heritage-adjacent, river-frontage, or contamination-clearance sites.
Planning Controls — City of Parramatta Council
Parramatta LEP 2023 & Parramatta DCP 2023. The City of Parramatta is Sydney's geographic centre and second CBD — a four-tier LGA spanning R4 high-rise apartment cores (Parramatta CBD, Westmead, Harris Park, Wentworth Point, Sydney Olympic Park, Telopea, Epping town centre), R3 station-precinct medium density, R2 detached suburban cores (Carlingford, Oatlands, Northmead, Dundas, Dundas Valley, Ermington, Rydalmere, North Parramatta, Old Toongabbie), and industrial-legacy redevelopment parcels (Camellia, Rosehill fringe, Silverwater, Sydney Olympic Park). R2 Low Density: FSR 0.5–0.55:1, building height 9m, front setback 6–7.5m, landscaped area 35–45%, deep soil 25%. R3 Medium Density along station precincts and major road corridors permits FSR up to 0.85:1 with heights 12–15m. R4 High Density on the Parramatta CBD core, Westmead Health Precinct, Harris Park, Wentworth Point peninsula, Sydney Olympic Park, Telopea Renewal Precinct and Epping town centre permits FSR 2.5–6:1+ with heights 50–150m+ — Parramatta hosts Sydney's tallest residential and commercial towers outside the CBD. Parramatta DCP 2023 enforces 600m² R2 dual-occupancy minimum. Heritage Conservation Areas in pockets covering Parramatta CBD heritage core (St John's Cathedral, Lancer Barracks, Old Government House precinct), Harris Park (UNESCO Old Government House World Heritage buffer), North Parramatta (Cumberland Hospital state-significant precinct + Female Factory), Westmead Boys' Home / Cumberland Hospital, parts of Carlingford, Beecroft fringe, Epping village, Oatlands, Northmead, Federation streets in Dundas, Dundas Valley, Rydalmere riverfront. Old Government House and the Government Domain at Parramatta Park are UNESCO World Heritage — buffer-zone planning controls extend to adjoining streets in Harris Park, Parramatta CBD, North Parramatta and parts of Westmead. Tree Preservation Order LGA-wide. Wianamatta Shale soil predominant; Class P/E alluvial soil with elevated water table on the Parramatta River corridor (Rydalmere, Ermington, Sydney Olympic Park, Wentworth Point, Camellia) requiring suspended slabs, Class P/E footings and dewatering on basement excavations. Industrial-legacy contamination management protocols apply to remediated parcels in Sydney Olympic Park (former Homebush Bay industrial/abattoir/Union Carbide), Wentworth Point (former industrial), Camellia (former Shell Oil refinery), Rosehill industrial fringe, Rydalmere (former industrial), Silverwater (current industrial transitioning) and Ermington (former Department of Defence, Boys Town). Riparian setbacks 10–60m on Parramatta River, Toongabbie Creek, Duck River and Parramatta River tributaries. Foreshore Building Line restrictions on direct waterfront in Wentworth Point, Sydney Olympic Park, Rydalmere, Ermington. Aircraft Noise overlays affect Sydney Olympic Park and Wentworth Point on the helicopter routes serving the Olympic Park heliport. Sydney Metro West (under construction, opening 2032) is the LGA's signature infrastructure event — stations at Parramatta CBD, Westmead, Sydney Olympic Park, Rosehill (planned) drive station-precinct redevelopment under specific 400m TOD overlays. Parramatta Light Rail Stage 1 (Carlingford–Westmead via Camellia–Rydalmere–Telopea–Dundas–Carlingford, opening 2024) anchors Stage-1 corridor R3/R4 redevelopment. Parramatta Light Rail Stage 2 (Parramatta CBD–Sydney Olympic Park via Camellia and Wentworth Point) opens further density precincts. Westmead Health Precinct (Westmead Hospital, The Children's Hospital, Westmead Private, Cumberland Hospital, Sydney Children's Hospital Network) anchors LGA employment with hospital-staff demand driving granny flat rental yield. Sydney Olympic Park is a master-planned event-and-residential precinct with apartment-only redevelopment under SREP 24 (Sydney Olympic Park) controls. Wentworth Point is a master-planned waterfront residential peninsula. Telopea Renewal is a UrbanGrowth NSW master-planned light-rail-corridor renewal precinct (post-war public housing replaced by 4,000+ apartment dwellings). Parramatta CBD is undergoing the largest commercial and residential tower redevelopment outside the Sydney CBD core — tallest residential tower outside Sydney CBD (Aspire Tower, 90 stories) and commercial towers Walker Corp, ATO, NSW Government precinct.

Building in Wentworth Point — Local Context
Site & Ground Conditions in Wentworth Point
Wentworth Point sits on Class M (Wianamatta Shale predominant) / Class P/E (alluvial Parramatta River corridor: Rydalmere, Ermington, Sydney Olympic Park, Wentworth Point) / industrial-legacy contamination overlays on Camellia, Rosehill, Silverwater fringe and Sydney Olympic Park soil — extremely reactive clay. For a knockdown rebuild, that rules out the cheapest off-the-shelf slab designs straight away. and pushes engineered footings into the $45,000–$80,000 range on most N/A (apartment-led precinct) blocks here. Geotechnical testing isn't optional — every Buildana rebuild in Wentworth Point 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 Wentworth Point's topography can collect water against rear setbacks if the contour survey is sloppy.
What City of Parramatta Council Wants to See
Approval in Wentworth Point comes down to documentation quality. City of Parramatta Council processes a high volume of residential applications, and the ones that get approved fast share three traits: clean drawings that show every required setback dimension on plan; a BASIX certificate that matches the actual specification (not a stand-in); and an engineering package sized correctly for the Class M (Wianamatta Shale predominant) / Class P/E (alluvial Parramatta River corridor: Rydalmere, Ermington, Sydney Olympic Park, Wentworth Point) / industrial-legacy contamination overlays on Camellia, Rosehill, Silverwater fringe and Sydney Olympic Park ground. We prepare every document at full lodgement standard the first time.
Cost vs Value in Wentworth Point
Median sale price in Wentworth Point is $750K–$1.5M (apartments). 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 Wentworth Point 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.
Wentworth Point Housing Stock & What That Means
Most homes in Wentworth Point were built 2010s+ apartment towers. Modern homes in this era generally have no asbestos, though survey is still standard before any major works.
Why Some Wentworth Point Builds Stall
Builds in Wentworth Point stall for predictable reasons. Lodgement defects (missing BASIX, wrong drawing scale, undeclared overlays). Soil surprises on Class M (Wianamatta Shale predominant) / Class P/E (alluvial Parramatta River corridor: Rydalmere, Ermington, Sydney Olympic Park, Wentworth Point) / industrial-legacy contamination overlays on Camellia, Rosehill, Silverwater fringe and Sydney Olympic Park ground when the builder didn't commission a borehole upfront. Variation creep when the contract was light on inclusions. Trade scheduling gaps when the builder is over-committed across too many sites. City of Parramatta Council delays when neighbour objection triggers committee review. Buildana protects against each of these at contract stage — fully documented lodgement pack, geotech in the price, itemised inclusions instead of allowances, and a tight project-manager-to-job ratio that keeps trades moving.
Builder's Take on Wentworth Point
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. Wentworth Point residents who KDR rarely regret it; the ones who renovate instead often tell me they wish they'd gone the rebuild path.
Clients often ask whether to keep the existing slab. Almost always no. 2010s+ apartment towers-era slabs in Wentworth Point weren't engineered for Class M (Wianamatta Shale predominant) / Class P/E (alluvial Parramatta River corridor: Rydalmere, Ermington, Sydney Olympic Park, Wentworth Point) / industrial-legacy contamination overlays on Camellia, Rosehill, Silverwater fringe and Sydney Olympic Park soil to today's standards. Trying to match new construction to old footings creates structural liability. Full slab replacement is cleaner and cheaper in the long run.
