Torrens Title vs Strata Title Duplex — What Is the Difference?

When you build a duplex and want to sell the dwellings separately, you need to subdivide. In NSW, there are two subdivision options: Torrens title and strata title. Each has different costs, legal implications, and buyer appeal. Buildana (Lic. 487805C) advises on the best option for each project based on the block, the design, and the development goals.

Torrens Title Subdivision

Torrens title subdivision divides the land into two (or more) separate lots. Each lot has its own title deed, its own boundaries, and its own independent services. There is no common property and no strata plan.

Advantages: • Each lot is completely independent — no body corporate, no strata levies, no common areas • Higher resale value — buyers pay a premium for Torrens title over strata. In Western Sydney, the premium is typically 5–10 per cent • Simpler ownership — no disputes over shared driveways, shared walls, or common maintenance • Better financing — most lenders treat Torrens title dwellings identically to standard houses. No strata report required for mortgage approval.

Disadvantages: • Higher subdivision cost: $30,000–$60,000 (surveyor, solicitor, council contributions, Sydney Water compliance, plan registration) • Longer timeline: 3–6 months for the subdivision process • Requires physical separation of services — each lot must have independent water, sewer, stormwater, electricity, and gas connections • May require wider blocks — each lot must meet minimum lot size and frontage requirements under the council's LEP

Strata Title Subdivision

Strata title subdivision creates a strata plan with individual lots (one per dwelling) and common property (shared driveway, shared party wall, possibly shared landscaping).

Advantages: • Lower subdivision cost: $15,000–$30,000 (strata plan registration, solicitor, common property definition) • Faster process: 2–4 months • Works on narrower blocks — no minimum individual lot size or frontage per dwelling • Services can be shared — one water meter with internal sub-metering, shared driveway

Disadvantages: • Body corporate required — even for a two-lot strata, a body corporate must be established with bylaws, levies, and meetings • Strata levies — ongoing quarterly levies for common property maintenance (shared driveway, shared insurance, shared landscaping). Typically $500–$1,500 per quarter per lot • Lower resale value — buyers discount for strata. Perceived as 'unit' rather than 'house' • Financing complexity — some lenders have restrictions on two-lot strata. Buildings below 50 sqm per lot may face lending restrictions • Owner disputes — party wall maintenance, driveway access, and noise are common friction points in two-lot stratas

Which Should You Choose?

Torrens title is almost always the better choice if your block and design support it. The higher subdivision cost ($15,000–$30,000 more than strata) is recovered many times over through higher sale prices and easier financing for purchasers.

Choose Torrens title when: • Block meets minimum lot size and frontage per dwelling (check council LEP) • Both dwellings can have independent service connections • You plan to sell one or both dwellings • You want maximum sale price per dwelling

Choose strata when: • Block does not meet minimum requirements per lot for Torrens title • You are retaining both dwellings as investments (strata levies are less relevant when you are paying them to yourself) • Budget is tight and you need to minimise subdivision cost • Development is a battle-axe or irregular block where Torrens boundaries are impractical
