Quick Answer

A duplex in Leumeah costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Campbelltown City Council approvals, construction and subdivision under one fixed-price contract.

Dual Occupancy Developments in Leumeah

A duplex in Leumeah is a feasible dual-occupancy on the lots that clear the Campbelltown 500m2 minimum, with R3 adding options and its own station. This suburb runs 1970s to 1990s brick veneer on 500 to 700m2 R2 blocks, so most clear 500, and R3 Medium Density along the station precinct means a well-placed lot may suit medium density. At an $850K to $1.1M median a Torrens-title duplex on a qualifying lot is a sound play with strong renewal around the station.

The ground is engineered off geotech to suit the specific lot, and on a qualifying R2 lot a side-by-side duplex works cleanly. There are no broad heritage overlays, which keeps the approval path predictable. Where the existing home carries fibro a licensed asbestos strip-out comes first.

What I would check first on your Leumeah block: whether it clears the 500m2 minimum, any R3 potential near the station, and the frontage. Those set the dual-occ.

We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what dual-occupancy it carries.

Buildana manages the full duplex development process in Leumeah — 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.

How It Works

From First Call to Final Key

Everything that has to be right before we touch the ground. Feasibility covers the planning side and the financial side. Yes-or-no on whether the block supports dual occupancy under Campbelltown City Council controls, plus indicative end values, build cost, and likely yield. The point is to kill bad sites before you spend on design — not after. Dual occupancy floor plans designed for your Leumeah block — attached or detached configuration, vehicle access, private open space, and full Campbelltown City Council compliance.

The Leumeah construction phase. Fixed price, programmed, supervised. Full approval management: Statement of Environmental Effects, plans, reports, and all supporting documentation lodged with Campbelltown City Council or private certifier. We handle RFIs and conditions. CC follows. 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.

The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Both dwellings handed over with individual Occupation Certificates. Subdivision lodged for separate titles. Separate metering installed. 6-year structural warranty per dwelling.
