Duplex Builder Wentworth Point — CDC-Ready Designs, 15-Day Approval
Wentworth Point 2127 duplex specialists. Compliant design means CDC approval in ~15 business days, construction complete in 10–14 months. Feasibility within 48 hours.
Quick Answer
A duplex in Wentworth Point costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, City of Parramatta Council approvals, construction and subdivision under one fixed-price contract.
Building Duplexes in Wentworth Point
There is no duplex market in Wentworth Point because there is no detached land. The suburb is a master-planned apartment precinct built from the 2010s on the former Homebush Bay industrial site, R4 towers on strata lots with zero freestanding stock to knock down. Parramatta's 600m² R2 minimum technically exists in the LGA rulebook. It just has nothing here to apply to. Anyone marketing you a Wentworth Point duplex site is selling something that is not there.
If dual occupancy is the actual goal, the land is one suburb over. Ermington, Melrose Park and the Parramatta corridor hold the R2 blocks this precinct never had, at entry points a Wentworth Point apartment owner trading up can reach. Industrial-legacy remediation controls govern what little ground remains here regardless.
What I would check first if a duplex is the goal: the nearby R2 suburbs that actually carry detached land, your budget, and the area you want. Those point you to real sites.
We build these fixed-price, licence HBL 487805C. Tell us your budget and the area you want, and we will point you at land that can actually carry two dwellings.
Buildana manages the full duplex development process in Wentworth Point — from feasibility assessment and architectural design through to DA or CDC approval, and fixed-price construction to dual handover. One builder, one contract, two homes.

No detached land, no duplex
Wentworth Point is a master-planned apartment precinct built from the 2010s on the former Homebush Bay industrial site, R4 towers on strata lots with zero freestanding stock to knock down. Parramatta's 600m² R2 minimum exists in the rulebook but has nothing here to apply to.
So anyone marketing a Wentworth Point duplex site is selling something that is not there. We say that plainly rather than take a fee to chase it.
The land is one suburb over

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Quick desktop check first — lot size, zoning, frontage — then full site visit if it stacks. Drainage path, neighbour overlooking, slope, services, easements. 600m² (R2) under Parramatta DCP 2023 minimum is just the entry ticket; the real feasibility is whether two compliant dwellings actually fit and sell. Our architect designs both dwellings to maximise your Wentworth Point block's yield — floor plans, elevations, 3D renders, and landscape concept. We optimise for rental return and sale value under City of Parramatta Council's DCP.
⏱The Wentworth Point construction phase. Fixed price, programmed, supervised. Most Wentworth Point duplexes go DA route through City of Parramatta Council — CDC pathways for dual occupancy are restrictive on most R2 blocks. We pre-meet with council planners on borderline sites to confirm support before lodgement, which avoids a 3-month round trip on RFIs. Both dwellings built simultaneously — engineered slabs (Class M soil), frame, lock-up, fit-out. Milestone updates from your project manager.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspections, dual OCs issued, subdivision registered with LRS. Each dwelling gets its own title, services, and 6-year structural warranty. Ready to rent, sell, or occupy.
⏱Quality Promise
We build duplexes in Wentworth Point end-to-end — feasibility, design, DA/CDC, dual-slab construction, subdivision. One contract.
