A duplex in Yennora costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Fairfield City Council approvals, construction and subdivision under one fixed-price contract.
Dual Occupancy Developments in Yennora
A duplex in Yennora leans on the station, because the residential pockets sit tight against the rail line and the industrial land. Lots run 450 to 700m2 of R2, so the larger ones clear the Fairfield 600m2 minimum and the smaller ones fall short. On 1950s to 1970s stock at a $900K to $1.15M market, a qualifying block plus that station access gives a completed duplex real rental pull.
The ground is moderately to highly reactive clay, so footings and the slab are engineered to suit across both dwellings. The older post-war stock nearly always carries asbestos, so a licensed strip-out is the first job on site. A side-by-side works once the frontage checks out.
What I would check first on your Yennora block: the area against 600m2, the frontage, and whether the block backs onto or fronts the industrial edge. Those shape the design and the value.
We build these fixed-price, licence HBL 487805C, from the Fairfield office close by. Send me the block and I will tell you what it holds.
Buildana manages the full duplex development process in Yennora — 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.

Station-side feasibility
Yennora lots run 450 to 700m2, so the larger ones clear the Fairfield 600m2 minimum while the smaller ones need checking.
The suburb has its own station, which is the value driver for a completed duplex, even with the industrial land nearby.
Post-war ground and stripping
The moderately to highly 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 slabs go down.

How It Works
From First Call to Final Key
Site visit, title search, and planning assessment for your Yennora block. We check lot dimensions against Fairfield City Council's minimum (600m²), review overlays, drainage, access, and services. You get a clear yes/no on duplex feasibility plus estimated yield.
⏱Design has to satisfy four audiences at once: Fairfield City Council, the future buyer or tenant, the certifier, and you. Each pull in a different direction — our job is to land plans that work for all four. Solar access, privacy, parking, POS, FSR, all balanced.
⏱We lodge and chase your approval — DA through Fairfield City Council for most duplexes, or CDC where eligible. R2 Low Density zoning in Yennora. CC issued, conditions cleared, ready to build.
⏱Building both sides in parallel halves the loan interest holding cost vs sequential builds. Bulk material orders for cabinetry, tiles, fixtures cut unit cost. Single site setup, single supervisor, single insurance period — efficiency compounds across the whole programme.
⏱Strata or Torrens title subdivision completed. Separate OCs, individual metering, 6-year structural warranty per dwelling. Strong rental demand near Yennora station.
⏱Quality Promise
We build duplexes in Yennora end-to-end — feasibility, design, DA/CDC, dual-slab construction, subdivision. One contract.
