Granny Flats Designed for South Turramurra Blocks
A granny flat in South Turramurra is a premium, family-driven build with an engineering edge to it. On 800 to 1,500m² blocks in the Lane Cove River valley, a secondary dwelling is guest accommodation, a studio or multigenerational space — the lot clears the 450m² Housing SEPP threshold with room to spare.
The catch here is the ground. South Turramurra sits in the valley with steeper, more reactive blocks than its ridge-top siblings — clay soil pockets grading Class H to E where the valley deepens. That means engineered slab and retaining design, which adds cost against a flat ridge block, so the geotech is the first thing I scope.
The family-oriented cul-de-sac streets and the Browns Field reserve give the suburb its quiet character. There's no station of its own, so a second dwelling here is about family, not yield.
We build to suit the block, fixed-price, licence HBL 487805C. Geotech and slope scoped before design starts.
Buildana manages the full granny flat process in South Turramurra — from site assessment and CDC fast-track approval through to fixed-price construction and handover. We build studio, 1-bedroom, and 2-bedroom designs up to the NSW maximum of 60m².

Family-driven, valley blocks
On 800 to 1,500m² valley blocks, a South Turramurra secondary dwelling is guest accommodation, a studio or multigenerational space — the lot clears the 450m² Housing SEPP threshold with room to spare.
The quiet cul-de-sac streets suit family use rather than a weekly-rent play.
Slope and reactive clay
South Turramurra sits in the valley with steeper, more reactive blocks than its ridge-top siblings — clay pockets grading H to E where the valley deepens.
That means engineered slab and retaining design off a real geotech, which adds cost against a flat block — so I scope the geotech and slope first.
