Split-Level Home in Toorak Gardens, Eastern Adelaide
A split-level home is designed to step down or up a sloping block, following the natural contour rather than fighting it. Done well it saves tens of thousands in retaining walls and cut and fill. Done poorly it becomes an expensive lesson in why a sloping block is not just a flat block with a discount.

The 3 decisions that shape your split-level home in Toorak Gardens
Cut and fill versus split-level
Cutting a sloping block flat can add $30k to $100k in earthworks and retaining. A split-level design absorbs the slope into the floor plan instead.
Which levels get which rooms
The classic Adelaide split puts living upstairs for the view and bedrooms downstairs for cooler sleeping. But the right answer depends on your block's aspect.
Access and future proofing
Stairs between levels can make a split-level house harder to age in. Ask about lift-ready cavities during design if you plan to stay long-term.
Split-Level Home FAQs for Toorak Gardens
What slope justifies a split-level design?▾
Generally anything with more than 1.5 metres of fall across the building envelope. Below that a flat-block design with modest cut is usually cheaper.
Are split-level homes more expensive to build?▾
On a like-for-like flat block they cost more. On a sloping block a well-designed split-level is often cheaper than a flat design that requires extensive earthworks.
Can I get a split-level home from a project builder?▾
Some project builders offer sloping-block ranges. Custom builders and design-and-construct firms handle genuine split-level design better because each block is different.
What about drainage on a slope?▾
Councils require detailed stormwater plans on sloping sites. Ag drains, subsoil drains and retaining wall weep holes all matter. Get the civil engineer involved early.
Will a split-level home resell easily?▾
In sloping-block suburbs, yes. Good split-level design is prized. In flat-block suburbs a split-level design is unusual and can narrow your buyer pool.
