A duplex in Kirrawee works on the R2 lots that clear the Sutherland 700m2 minimum, while R3 and R4 around the station open density. This station-precinct suburb runs 1960s to 1990s fibro and brick on the original streets, with 2010s apartment towers around the station, so near the centre medium or high density is the higher use. On a larger R2 lot away from the station a Torrens-title duplex or townhouse can work under the R3 Medium Density controls.
The ground is engineered off geotech to suit the specific lot, and the Kirrawee Brick Pit redevelopment anchors the station precinct. On a qualifying lot a side-by-side works cleanly, and smaller lots fall short of 700. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Kirrawee block: whether it clears the 700m2 Sutherland minimum, whether R3 or R4 density applies near the station, and the frontage. Those set the best use.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you the best use of it.
Buildana manages the full duplex development process in Kirrawee — 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 density, R2 duplex
This station-precinct suburb runs 1960s to 1990s stock on the original streets, with apartment towers around the station.
Near the centre density is the higher use, while a larger R2 lot clearing the Sutherland 700m2 minimum suits a duplex or townhouse.
A clean dual-occ build
The ground is engineered off geotech to suit, and on a qualifying lot a side-by-side works cleanly.
Smaller lots fall short of 700, with older fibro stripped under licence first.

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 Sutherland Shire Council controls, plus indicative end values, build cost, and likely yield.
⏱Dual occupancy floor plans designed for your Kirrawee block — attached or detached configuration, vehicle access, private open space, and full Sutherland Shire Council compliance..
⏱Full approval management: Statement of Environmental Effects, plans, reports, and all supporting documentation lodged with Sutherland Shire 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.
