Duplex Builder Fairfield East — From $750K Fixed Price
Fixed-price duplex construction in Fairfield East 2165. Two dwellings, one contract, no variations. Minimum lot 600m². Free feasibility.
Fairfield East Dual Occ. — Feasibility to Handover
A duplex in Fairfield East is a feasible dual-occupancy on the lots that clear the Fairfield 600m2 minimum. This small suburb adjacent to Fairfield CBD runs post-war housing on standard blocks, so a Torrens-title duplex on a qualifying lot is a sound play close to the station and shops. Some standard lots fall short, so the area is the first check.
This is Fairfield City on reactive clay, so footings are engineered off geotech and the slab is detailed for the movement on both dwellings. On a qualifying block a side-by-side duplex works cleanly, and there are no broad heritage overlays. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Fairfield East block: whether it clears the 600m2 minimum, the reactive-clay footing design, 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 Fairfield East — 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
Feasibility covers the planning side and the financial side. Yes-or-no on whether the block supports dual occupancy under Fairfield 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 Fairfield East block — attached or detached configuration, vehicle access, private open space, and full Fairfield City Council compliance.
⏱Full approval management: Statement of Environmental Effects, plans, reports, and all supporting documentation lodged with Fairfield 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.
⏱Both dwellings handed over with individual Occupation Certificates. Subdivision lodged for separate titles. Separate metering installed. 6-year structural warranty per dwelling.
