Building Granny Flats in Turramurra
A granny flat in Turramurra is a premium, family-driven build. On 700 to 1,100m² blocks worth $2.8M to $4.2M, a secondary dwelling is guest accommodation, a studio or multigenerational space — the lot clears the 450m² Housing SEPP threshold with room to spare.
Heritage is the variable. The Heritage Conservation Areas around the village limit demolition on certain streets and can push a secondary dwelling through a full DA rather than the fast CDC path — but the back-street blocks generally allow standard Council controls, so it comes down to exactly where you are. That's the first thing I check.
The soil grades Class M on the ridge with E pockets near drainage lines, so the slab is engineered off a real geotech to suit. Turramurra's village and national-park edge give the setting its character, and a second dwelling has to answer that.
We build to the standard the address demands, fixed-price, licence HBL 487805C. Heritage and soil scoped first.
Buildana manages the full granny flat process in 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.

Premium, family-driven
On 700 to 1,100m² blocks worth $2.8M to $4.2M, a Turramurra secondary dwelling is guest accommodation, a studio or multigenerational space — not a weekly-rent play. The lot clears the 450m² Housing SEPP threshold with room to spare.
That leaves room to site and design the dwelling properly rather than squeeze it in.
Heritage varies by street
The Heritage Conservation Areas around the village limit demolition on certain streets and can push a job through a full DA, but the back-street blocks generally allow standard Council controls — so it comes down to exactly where you are.
The soil grades M on the ridge with E pockets near drainage lines, so the slab is engineered off a real geotech to suit.
