A duplex in Woodpark costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Cumberland City Council approvals, construction and subdivision under one fixed-price contract.
Building Duplexes in Woodpark
A duplex in Woodpark is a quiet, individual-block call, because this is a small suburb tucked between Merrylands and Smithfield. It carries R2 and R3, and on R2 the larger of the 450 to 650m2 lots clear the Cumberland 600m2 minimum. On a $1.0M to $1.3M market a Torrens-title duplex on a qualifying block is a sound play, but with a small suburb the stock varies, so each block is assessed on its own.
The ground is moderately reactive clay, so footings and the slab are engineered to suit across both dwellings. The 1950s to 1970s stock nearly always carries asbestos, so a licensed strip-out comes first. A side-by-side works once the frontage checks out.
What I would check first on your Woodpark block: the zoning, then the area against 600m2 and the frontage. Small suburbs like this reward checking the individual lot rather than assuming.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what it holds.
Buildana manages the full duplex development process in Woodpark — 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.

Small suburb, individual check
Woodpark is a small suburb between Merrylands and Smithfield, so the stock varies and each block is assessed on its own.
It carries R2 and R3, and on R2 the larger 450 to 650m2 lots clear the Cumberland 600m2 minimum.
Reactive clay and stripping
The moderately reactive clay means footings and slab engineered to suit on both dwellings.
A 1950s to 1970s home almost always needs a licensed asbestos strip-out before the new work.

How It Works
From First Call to Final Key
A duplex is really a feasibility problem wearing a construction outfit. Before anything else, we verify your Woodpark block against Cumberland City Council's LEP — lot size, frontage, FSR, landscape area. If it doesn't stack up, you find out in a week, not after 3 months of design.
⏱Design runs dual from day one. Two dwellings, one coherent streetscape, party-wall acoustics and fire rating built into the structure rather than bolted on. The plan accommodates R2 Low Density & R3 Medium Density zoning without looking like two mismatched houses sharing a fence.
⏱Approval and construction get sequenced together. Slab pours are choreographed so the trades show up once, frame up both sides, and keep rolling. Two separate meters, two separate services, but one crew, one programme.
⏱Handover is dual. Both dwellings walked at the same time, both OCs in the same issue, both titles subdivided before settlement. You leave the final inspection with the option to live in one and rent the other, or to sell both.
⏱Quality Promise
Our Woodpark duplex projects run from feasibility to subdivision under one builder. Fixed price, dual handover, full compliance.
