KDR in Longueville is rare and heritage-restricted — Heritage Conservation Areas cover most streets. Where non-contributory replacement is viable, harbour-fall engineering dominates: suspended slabs, rock excavation $25K–$60K, structural underpinning. Demolition $50K–$85K. Realistic premium turnkey $2.2M–$4M for 320–480m² rebuild. Pre-construction 7–9 months.
Practical realities of knocking down and rebuilding in Longueville: Nearest rail is Wollstonecraft (4 km, ferry), which influences site access during construction (deliveries, cranage, skip placement). 600–1,400m² blocks usually have enough room for proper site set-up, but tight battle-axe lots and narrow frontages need staging plans factored into the build program. Lane Cove Council processes a steady volume of residential applications — clean documentation moves fast, and Buildana lodges everything at full standard the first time. Class M (sandstone ridges) / H–E (river fall) soil (extremely reactive clay) sets foundation cost in the $45,000–$80,000 range; budget allocation for that line item is fixed in your contract, not estimated.
Buildana manages the complete knockdown rebuild process in Longueville — 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 Longueville?
Longueville is the harbour-fall peninsula on the north side of Tambourine Bay and Woodford Bay. Federation mansions, inter-war heritage and contemporary harbour-fall builds on 600–1,400m² blocks. Heritage Conservation Areas cover most streets. Sandstone-dominant with substantial fall to the water. Lane Cove River and Woodford Bay frontage. Premium for harbour outlook.
Longueville's established streetscape and median house prices of $3.5M–$7.5M reflect a premium location within Lane Cove. Building costs sit above the metro average, offset by stronger capital growth and rental returns. Transport access via Wollstonecraft (4 km, ferry) connects Longueville to the wider Sydney network. 1880s–1940s heritage-era housing stock across Longueville is prime for knockdown rebuild — replacing dated layouts and materials with modern, NCC-compliant homes that maximise block potential. Ground conditions (Class M (sandstone ridges) / H–E (river fall)) across Longueville are well understood by local builders — Buildana's engineering accounts for extremely reactive soil movement.
KDR in Lane Cove works the village R2 detached stock and inland Lane Cove North — Heritage Conservation Areas restrict scope on Greenwich, Longueville, Northwood and Linley Point peninsulas where extension/restoration dominates. Sandstone-dominant soil; rock excavation $20K–$50K typical, deeper on river-fall lots. Demolition $40K–$80K with asbestos prevalent in pre-1990 stock. Realistic premium turnkey $1.6M–$3.5M for 280–450m² build. Bushfire BAL ratings drive material upgrades $15K–$50K on bush-edge lots in Lane Cove West and Riverview. Pre-construction 4–7 months including heritage and tree consents on protected streets.
Planning Controls — Lane Cove Council
Lane Cove LEP 2009 & Lane Cove DCP 2010. R2 Low Density dominates the LGA: FSR 0.5:1, building height 9.5m, front setback 7.5–9m varying by streetscape, landscaped area 35–40%. R3 Medium Density along Burns Bay Road, Longueville Road and the Lane Cove village core permits FSR up to 0.8:1. R4 High Density and B4 Mixed Use along the St Leonards / Crows Nest fringe in Lane Cove North. The 2024 Crows Nest Metro SEPP TOD precinct overlay reaches the south-eastern portion of Lane Cove North, opening density bonuses inside 400m of Crows Nest Metro station. Heritage Conservation Areas cover most older streets in Greenwich, Longueville, Northwood, Linley Point, Lane Cove West, Riverview and parts of Lane Cove village. Tree Preservation Order applies LGA-wide. River-fall and harbour-fall sites on the Lane Cove River and Sydney Harbour peninsulas (Greenwich, Longueville, Northwood, Linley Point) require engineered slab and retaining design — sandstone rock excavation $20K–$60K standard. Lane Cove National Park frontage on Lane Cove West and Riverview adds bushfire BAL ratings on bush-edge lots.

Building in Longueville — Local Context
Longueville Block Realities
Typical Longueville blocks are 600–1,400m² on Class M (sandstone ridges) / H–E (river fall) ground (extremely reactive clay). For a rebuild, the structural envelope is more constrained than the headline lot size suggests — once you subtract setbacks, easements, landscaped area requirements, and any tree preservation, the actual buildable area is usually 35-45% of the block. We map that early in the feasibility stage so you're designing to what's actually allowed, not what looks possible from the title plan. Foundation cost band on most Longueville blocks: $45,000–$80,000.
Lane Cove Planning Context
Lane Cove has its own LEP and DCP layered over State planning controls. For knocking down and rebuilding in Longueville, the practical impact: Lane Cove Council's DCP sets local rules for streetscape character, materials palette in some precincts, vehicle crossover widths, and tree retention. R2 Low Density / R3 Medium (Lane Cove village) zoning on most Longueville blocks permits single dwellings, alterations, and additions. Buildana checks every overlay (heritage, bushfire, flood, acid sulfate soil, biodiversity) before quoting.
What a Rebuild Costs in Longueville
Longueville's median house price sits at $3.5M–$7.5M. That's the number that decides whether a knockdown rebuild stacks up financially. A new build at $3.5M–$7.5M+ replacement is well-supported by the local market and adds resale headroom on standard 600–1,400m² blocks. Buildana provides itemised quotes — no provisional sums, no allowances, no "as per engineering" line items.
Longueville Housing Stock & What That Means
Most homes in Longueville were built 1880s–1940s heritage. 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.
Building Activity in Longueville Right Now
Longueville is seeing steady residential activity — 1880s–1940s heritage-era stock is reaching end-of-life on dozens of streets, driving steady knockdown rebuild activity month over month. Buildana sits inside that pipeline — we know what's getting approved, what's stalling, and why.
Builder's Take on Longueville
Clients often ask whether to keep the existing slab. Almost always no. 1880s–1940s heritage-era slabs in Longueville weren't engineered for Class M (sandstone ridges) / H–E (river fall) soil to today's standards. Trying to match new construction to old footings creates structural liability. Full slab replacement is cleaner and cheaper in the long run.
1880s–1940s heritage Longueville 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.

How It Works
From First Call to Final Key
Site visit covers everything that affects the build cost: vehicle access for trucks and crane, services (sewer depth, water connection, electrical service rating), soil exposure for borehole, neighbouring construction, and any obvious heritage or tree constraints. Real numbers, not estimates.
⏱Architectural design for your replacement home, structural engineering for Class M (sandstone ridges) / H–E (river fall) soil, BASIX certification, and all approval documentation. Lodged as CDC (10–15 days) or DA (40–90 days) depending on design.
⏱Demolition runs 5–10 working days for a standard Longueville cottage — longer if asbestos volume is significant or the structure includes a brick chimney or solid-block walls. Asbestos work happens first under a controlled removal program before mechanical demo starts.
⏱New home built from engineered slab (Class M (sandstone ridges) / H–E (river fall) soil) to keys — fixed-price, milestone-based progress payments. Your project manager provides weekly updates.
⏱Walk through your finished home on your original Longueville block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule. Move in.
