Building on titled land in Adelaide: Four common myths, and what buyers should know
Titled land is often seen as the finish line. For Adelaide buyers, it’s the starting point for construction, and getting the next steps right can save time and money.
South Australia has a unique place in the history of land ownership. The Torrens title system, now used around the world, was introduced in South Australia in 1858, giving landowners a clear, government-backed record of who owns each parcel of land.
More than 165 years later, title remains the milestone that matters for buyers in Adelaide’s new estates, from Angle Vale in the north to Seaford Heights in the south. A block becomes a separate legal lot once the developer’s plan of division is deposited and certificates of title are issued through the Lands Titles Office, allowing the buyer to settle and take ownership.
Yet there are still plenty of misconceptions about what happens next. Here are four of the most common.
Myth 1: “Once my land titles, I can start building straight away”
Titling allows the land to settle, but a home can’t go up until it has development approval.
In South Australia, new homes are assessed under the state’s Planning and Design Code, with applications lodged through the PlanSA portal. A new home generally needs both planning consent and building rules consent before construction can begin, and many new estates also require the design to be checked against their own design guidelines first.
The good news is much of this can be prepared before the land titles. Buyers who have chosen their home design early can have plans ready to lodge as soon as the site information is available.
Myth 2: “All blocks cost the same to build on”
Two neighbouring blocks can come with very different construction costs.
Adelaide is known for reactive clay soils, which expand and contract as moisture levels change. Once the land has settled, a soil test determines the site classification, and highly reactive sites can require a deeper or more heavily reinforced slab. A contour survey shows whether the block falls enough to need retaining walls or cut and fill. In some areas, planning overlays such as bushfire or flood requirements can also shape the design.
Understanding these factors early gives buyers a clearer picture of their total build cost before they sign a building contract.
Myth 3: “Stamp duty will eat into my building budget”
For eligible first home buyers, that’s no longer the case in South Australia.
Since 6 June 2024, eligible first home buyers purchasing vacant land to build their first home pay no stamp duty, regardless of the land’s value. They may also be eligible for the $15,000 First Home Owner Grant when building a new home, with no property value cap.
The impact has been significant. The South Australian Government reports $73.5 million in stamp duty relief was provided to 3,705 households buying a new home or vacant land in 2024–25, with the average first home buyer around $51,000 better off when the grant is included.
Eligibility conditions apply, so buyers should confirm their position with RevenueSA before signing.
Myth 4: “There’s no point choosing a builder until the land is ready”
Waiting can leave buyers exposed to price changes and delays once their land titles.
Choosing a builder early allows the design, inclusions and site costs to be worked through in advance, so finance and approvals can move quickly once settlement occurs. It also gives buyers a clearer picture of the total cost of their land and home together.
Simonds Homes’ Titled Land Advantage campaign in South Australia is built around this timing. It’s available to buyers who already hold titled land, as well as those whose land is expected to title by 31 March 2027, and offers savings off the advertised base price of selected homes until 15 November 2026.
Buyers whose land is still titling can also benefit from Simonds’ 12-month price hold, which starts when the $500 initial fee is paid. That fee must be paid by 15 November 2026, after which sales acceptance, sales documentation and the building contract follow within set 14-day timeframes.
Every home is supported by Simonds’ fixed price guarantee, guaranteed site start and Lifetime Structural Guarantee for the original homeowner. Eligibility criteria and terms and conditions apply.
