A duplex in Chester Hill is a feasible dual-occupancy on the lots that clear the Canterbury-Bankstown 600m2 minimum, with its own station. This suburb runs post-war housing on standard blocks with active residential renewal, and at a $950K to $1.15M median a Torrens-title duplex on a qualifying lot is a sound play with real yield and rail connectivity. Some standard lots fall short, so the area is the first check.
The ground is engineered off geotech to suit the specific lot, and on a qualifying block 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 Chester Hill block: whether it clears the 600m2 minimum, the frontage for a side-by-side, and any asbestos in the older home. 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 Chester Hill — 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 Canterbury-Bankstown Council controls, plus indicative end values, build cost, and likely yield.
⏱Dual occupancy floor plans designed for your Chester 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.
