A knockdown rebuild in South Turramurra costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Ku-ring-gai Council approvals, and construction under one fixed-price contract.
New Home on Your South Turramurra Block
South Turramurra KDR runs into soil and slope before anything else — Class H to E reactive clay, drainage, and retaining wall requirements add $40K–$100K to the foundation budget on a typical block. Browns Field on the south. Existing post-war stock often poorly drained, with damp issues that demolition reveals. Block sizes 800–1,500m². Realistic KDR turnkey: budget the engineering before the architecture.
Most South Turramurra blocks run 800–1,500m² on Class M–H ground. Knockdown rebuild on 1920s–1960s (heavy heritage stock) stock here usually pencils out better than deep renovation once you tally up structural, electrical, plumbing, insulation, and waterproofing upgrades against full replacement value. Median price band: $2.8M–$4.2M. Nearest rail is Turramurra (2 km).
Buildana manages the complete knockdown rebuild process in South Turramurra — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

Why Knockdown Rebuild in South Turramurra?
South Turramurra sits in the Lane Cove River valley with steeper, more reactive blocks than its sibling suburbs. Browns Field and Browns Forest reserve frame the southern edge. Lots run 800–1,500m² with clay soil pockets (Class H to E) where the valley deepens — engineered slab and retaining design adds cost compared to ridge-top Turramurra. Cul-de-sac streets, family-oriented, no station of its own.
South 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. Transport access via Turramurra (2 km) connects South Turramurra to the wider Sydney network. 1920s–1960s (heavy heritage stock)-era housing stock across South Turramurra is prime for knockdown rebuild — replacing dated layouts and materials with modern, NCC-compliant homes that maximise block potential. Ground conditions (Class M–H) across South Turramurra are well understood by local builders — Buildana's engineering accounts for moderately to highly reactive soil movement.
Knockdown rebuild in Ku-ring-gai is its own discipline — every job starts with a heritage check, a tree report, and a streetscape character assessment before a concept goes anywhere near a block. Council's Heritage Conservation Areas cover significant portions of Gordon, Killara, Pymble, Wahroonga, Warrawee, Roseville and Turramurra; demolish without consent and you lose the lot. Blocks generally run 800–1,400m² with Class M soil on the sandstone ridge and reactive H pockets in the Lane Cove valley suburbs (East Killara, South Turramurra, West Pymble, East Lindfield). Demolition costs run $35K–$60K because most of the housing stock is asbestos-era brick or fibro and the Tree Preservation Order limits site clearing. CDC is rarely the right pathway in Ku-ring-gai — full DA is the realistic plan, with 12–18 weeks typical assessment. Realistic KDR budget for a 350m² premium two-storey rebuild on a Pymble or Wahroonga block: $1.6M–$2.6M turnkey, depending on finish level.
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 South Turramurra — Local Context
Ground Conditions That Affect Your Build
Class M–H is the rule across South Turramurra — moderately to highly reactive clay. For your knockdown rebuild, expect engineered footings in the $24,000–$42,000 range. The variables that shift you up or down inside that band: building footprint, number of storeys, point loads (heavy stone benchtops, masonry feature walls), and whether the adjacent stormwater system needs upgrading. South Turramurra is close to Turramurra (2 km) station — site access on tighter blocks adds a logistics premium, which is why we cost cranage and material delivery before signing, not after.
Planning Controls in South Turramurra
South Turramurra is zoned R2 Low Density. Ku-ring-gai Council controls FSR, height limits (typically 8.5–9m), site coverage, landscaped area minimums, and setbacks. For a rebuild, the binding constraints on most 800–1,500m² blocks here are: front setback (around 4.5–6m), side setbacks (1.0–1.5m articulated), rear (3–6m depending on lot depth), and landscaped area (usually 35–40%). Buildana's design team works to those numbers from the first sketch — no late re-design when council comes back with comments.
Realistic Budget for South Turramurra
For a knockdown rebuild in South Turramurra, the budget conversation starts with what you actually want versus what the site supports. Most quotes you'll get from volume builders strip out the things that matter on Class M–H soil — engineered slab upgrade, decent waterproofing, real drainage design, BASIX-compliant glazing — and present them as variations after you sign. We don't do that. Buildana's contract is fixed-price including everything required to deliver a rebuild that complies with NCC 2025 on a 800–1,500m² block in South Turramurra.
South Turramurra Housing Stock & What That Means
Most homes in South Turramurra were built 1920s–1960s (heavy heritage stock). That puts asbestos risk firmly in play — sheeting, eaves linings, vinyl floor tiles, and pipe lagging are likely. Licensed removal adds $5,000–$25,000 to a rebuild where demolition is involved, and Buildana manages SafeWork NSW notifications, removal, and clearance certificates as part of the contract.
What Recent Approvals Show
Ku-ring-gai Council's recent decisions for Rebuilds in South Turramurra reveal a clear pattern — applications that demonstrate genuine understanding of Ku-ring-gai Council's DCP — not just the State controls — progress materially faster. Sloppy lodgement adds 4-8 weeks of round-trip; clean lodgement doesn't.
Builder's Take on South Turramurra
1920s–1960s (heavy heritage stock) South Turramurra homes are often asbestos-affected — not always, but often enough that the demolition quote should include contingency. AL/A-class licensed removal runs $8K–$25K on top of standard demolition. Any builder who doesn't flag this is either inexperienced or setting up a variation.
Service abolishment and reinstatement in South Turramurra typically costs $3K–$8K. Sydney Water cap-off, Endeavour Energy disconnection, gas cap. Cheap KDR quotes often bundle this into "demolition" as a line item worth $1K — which is wrong and gets billed later.
