A granny flat in Turramurra costs $150,000–$300,000+ depending on size and finishes. 1-bed from $150K, 2-bed from $200K. CDC fast-track approval in 10–15 business days. Buildana manages design, Ku-ring-gai Council approval and fixed-price construction.
Building Granny Flats in Turramurra
Granny flat in Turramurra clears $650–$800/week. Block sizes 700–1,100m² are tight for a comfortable 60m² secondary dwelling under the 50% landscaped area requirement, but most lots make the math work. Heritage Conservation Areas around the village core push to DA pathway. Soil M on the ridge, E pockets near drainage. Realistic build cost $200K–$280K including engineered slab.
Most Turramurra blocks run 700–1,100m² on Class M ground. A granny flat under the Housing SEPP needs the lot above 450m², some clear backyard, and not much else by way of council process — CDC certifier sign-off in 10–15 business days, no DA through Ku-ring-gai Council required. Median price band: $2.8M–$4.2M. Local services anchor around Turramurra IGA village & Bobbin Head Road.
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.

Why Build a Granny Flat in Turramurra?
Turramurra is the central village of upper Ku-ring-gai — Bobbin Head Road heading east toward the national park, Pacific Highway shops, and a station on the T1 line. Heritage Conservation Areas around the village limit demolition options on certain streets, but the back-street blocks (700–1,100m²) generally allow KDR with standard Council controls. Soil grades M on the ridge with E pockets near drainage lines.
Turramurra's established streetscape and median house prices of $2.8M–$4.2M reflect a premium location within Ku-ring-gai. Building costs sit above the metro average, offset by stronger capital growth and rental returns. Turramurra benefits from Turramurra station on the doorstep — walkable rail access lifts both rental demand and property values. Secondary dwellings on 700–1,100m² blocks deliver rental returns of $650–$850/week per week. CDC approval through a private certifier typically takes 10–15 business days. Soil conditions in Turramurra (Class M, moderately reactive) are factored into every Buildana foundation design.
Granny flats in Ku-ring-gai run on a different economic logic to Western Sydney — block sizes of 800–1,400m² make compliance easy on paper, but the Tree Preservation Order, deep-soil 30% requirement, and 50% landscaped area control complicate every site plan. Bushfire BAL ratings apply in St Ives, North Turramurra, North Wahroonga and bush-edge lots — that adds $20K–$60K depending on the rating. The upside is rental: $650–$850/week is normal for a 60m² secondary dwelling in Killara, Wahroonga or Lindfield, with Pymble and Warrawee touching $900/week for full-spec finishes. CDC is available for SEPP-compliant designs but not on heritage or BAL-affected lots — DA is the safer route.
Planning Controls — Ku-ring-gai Council
Ku-ring-gai LEP 2015 & Ku-ring-gai DCP. R2 Low Density: FSR 0.3:1 on lots under 1,200m² (sliding down to ~0.27:1 on larger lots), building height 9.5m, front setback 9–12m varying by streetscape, landscaped area 50%, deep soil 30%. Heritage Conservation Areas cover significant portions of Gordon, Killara, Pymble, Wahroonga, Warrawee, Roseville and Turramurra — heritage character assessment is required before any DA. Tree Preservation Order is one of Sydney's strictest: any tree over 5m high or 0.45m trunk circumference needs Council consent before removal. Bushfire planning (Planning for Bushfire Protection 2019) applies in St Ives, St Ives Chase, North Turramurra, North Wahroonga and bush-edge lots — BAL assessment is mandatory. The 2024 NSW TOD reforms permit medium density inside 400m of Roseville, Lindfield, Killara, Gordon, Pymble, Turramurra and Warrawee stations, but Council scrutiny on built form and tree retention remains heavy.

Building in Turramurra — Local Context
What Turramurra Soil Means for Your Secondary dwelling
Most blocks across Turramurra (2074) classify as Class M — moderately reactive. Translation for a granny flat: foundation cost lands somewhere between $15,000–$32,000, depending on building footprint and how the engineer reads the borehole. Standard waffle raft slabs work on most Turramurra sites, sized by an engineer to the actual classification. Buildana includes the geotech report, structural engineering, and slab design in every quote. No site allowance, no provisional sum.
Ku-ring-gai Council & Approval Pathway
Turramurra sits inside the Ku-ring-gai LGA, governed by Ku-ring-gai Council. For a granny flat, the approval question is usually CDC vs DA. Most compliant designs in Turramurra fit CDC — Complying Development Certificate issued by a private certifier in 10–15 business days. That's the fast lane, and Buildana lodges it as part of the contract. Either way, we manage submission, RFIs, and re-lodgement in-house — you don't deal with the council.
Where the Money Goes on a Turramurra Secondary dwelling
Cost breakdown for a typical secondary dwelling in Turramurra: structure and frame around 30%, slab and foundations 8–14% (driven by Class M soil), roofing and external 10–12%, services (plumbing, electrical, HVAC) 12–18%, fit-out (kitchen, bathrooms, joinery) 18–25%, and finishes (paint, tiles, flooring) 8–12%. The remaining 4–6% covers approvals, certifications, and site establishment. Buildana itemises every line so you see what you're paying for — no lump sums hiding margin.
Designing for the Turramurra Streetscape
Turramurra's housing stock is predominantly from the 1920s–1960s (heavy heritage stock).. The local anchor is Turramurra IGA village & Bobbin Head Road. For a granny flat, the streetscape question matters more than most builders admit — a brand-new double-storey on a street of single-storey 1920s–1960s (heavy heritage stock) weatherboards will draw council attention on bulk and scale, even if technically compliant. Buildana designs the front elevation to read appropriately for the street while modernising the floor plan and structure behind it. Materials palette, roof pitch, fenestration rhythm — all chosen to settle into the existing rhythm rather than fight it.
Building Activity in Turramurra Right Now
Turramurra is seeing steady residential activity — secondary dwelling CDCs are being lodged at record rates as homeowners pursue rental income against rising mortgage costs. Buildana sits inside that pipeline — we know what's getting approved, what's stalling, and why.
Builder's Take on Turramurra
The trap on Turramurra granny flats: treating the 60m² SEPP cap as a goal rather than a ceiling. A well-planned 45m² 1-bedroom often rents for 80% of the full-size 60m² — with $40K less build cost. The rental yield actually improves. Size the build to the use, not the cap.
Separate meter is non-negotiable. Without it, rental income gets murky (who pays for electricity?) and lease compliance becomes a fight. Turramurra granny flats should be metered as a separate supply to the main home — $2.5K–$6.5K extra, saves five figures of dispute over a 10-year rental period.
