A duplex in Potts Hill 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.
Potts Hill Duplex Construction
A duplex in Potts Hill comes down to the block, in a small suburb built around the reservoir. Lots run 500 to 700m2 of R2, so the larger ones clear the Canterbury-Bankstown 600m2 minimum and the tighter ones fall short. On a $1.0M to $1.3M market with Birrong station a kilometre off, 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 1940s to 1970s post-war stock nearly always carries asbestos, so a licensed strip-out is the first job. A side-by-side works once the frontage checks out.
What I would check first on your Potts Hill block: the area against 600m2 and the frontage. Being a small suburb, each block is worth checking on its own.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what it carries.

Small suburb, block-by-block
Potts Hill lots run 500 to 700m2, so the larger ones clear the Canterbury-Bankstown 600m2 minimum.
It is a small suburb around the reservoir, so each block is assessed on its own rather than by a general rule.
Post-war ground and stripping
The moderately reactive clay means footings and slab engineered to suit on both dwellings.
A 1940s to 1970s 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 Potts Hill 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.
