Duplex in Georges River — what it actually takes in 2026
Duplex feasibility in Georges River works R3 medium-density along the Hurstville/Penshurst/Mortdale/Oatley/Riverwood/Beverly Hills station precincts (FSR 0.85:1) plus R2 detached pockets meeting 600m² minimum across the southern suburbs (Oatley, Peakhurst, Lugarno, Connells Point, Blakehurst). The 2024 NSW TOD reforms around Hurstville and Mortdale stations open major density bonuses for medium-density redevelopment within 400m. Heritage Conservation Areas in Hurstville, Penshurst, Oatley village restrict duplex on protected streets. Foreshore Building Line restricts duplex on Georges River frontage. End values $1.4M–$2.2M per attached dwelling on established core; $1.8M–$3.0M+ on premium Oatley, Lugarno, Connells Point. Mandatory paid feasibility — TOD precinct overlays, heritage and Foreshore Building Line controls change the maths.

Duplex Georges River — frequently asked questions
Can I build a duplex on my Georges River block?
Duplex feasibility depends on zoning (R2 detached or R3 medium-density), minimum lot size, frontage, FSR, setbacks, landscaped area, and overlays (heritage, bushfire, foreshore). Buildana runs a paid feasibility before any duplex contract — the planning answer determines everything.
Does Buildana handle subdivision after construction?
Yes — Buildana coordinates Torrens-title or strata subdivision at completion, including surveyor, plan registration and NSW Land Registry Services lodgement. The two new titles are the financial outcome of a duplex project.
What's the typical end value of a Georges River duplex?
End values vary widely by suburb tier within Georges River. Buildana provides a paid feasibility report covering construction cost, sale-comparable analysis, GST implications, and net return per dwelling — so you can sign with full numbers, not estimates.
