A duplex in Yagoona costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Canterbury-Bankstown Council approvals, construction and subdivision under one fixed-price contract.
Yagoona Duplex Construction
A duplex in Yagoona works on the blocks that clear the Canterbury-Bankstown 600m2 minimum, and the station in the suburb helps the case. Lots run 500 to 700m2 of R2, so the larger ones qualify and the tighter ones fall short. On a $1.0M to $1.25M market with active renewal through the streets, a Torrens-title duplex on a qualifying block is a sound play.
The ground is moderately reactive clay, so footings and the slab are engineered to suit across both dwellings. The post-war and 1960s 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 Yagoona block: the area against 600m2, the frontage, and the walk to the station, because that walk lifts the rent.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what it carries.
Buildana manages the full duplex development process in Yagoona — 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
Yagoona lots run 500 to 700m2, so the larger ones clear the Canterbury-Bankstown 600m2 minimum.
The station in the suburb plus active renewal give a completed duplex steady demand at the $1.0M to $1.25M market.
Reactive clay and stripping
The moderately reactive clay means footings and slab engineered to suit on both dwellings.
A post-war or 1960s home almost always needs a licensed asbestos strip-out before the new work.

How It Works
From First Call to Final Key
Feasibility covers the planning side and the financial side. Yes-or-no on whether the block supports dual occupancy under Canterbury-Bankstown Council controls, plus indicative end values, build cost, and likely yield.
⏱Dual occupancy floor plans designed for your Yagoona block — attached or detached configuration, vehicle access, private open space, and full Canterbury-Bankstown Council compliance..
⏱Full approval management: Statement of Environmental Effects, plans, reports, and all supporting documentation lodged with Canterbury-Bankstown Council or private certifier. We handle RFIs and conditions.
⏱Construction follows a tight programme: dual slabs in one mobilisation, paired frame stand, simultaneous lock-up, then trades rotate between sides for fit-out so no day is lost waiting on availability. The schedule is engineered, not optimistic.
⏱Both dwellings handed over with individual Occupation Certificates. Subdivision lodged for separate titles.
⏱Quality Promise
Our Yagoona duplex projects run from feasibility to subdivision under one builder. Fixed price, dual handover, full compliance.
