A granny flat in Longueville 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, Lane Cove Council approval and fixed-price construction.
Longueville Secondary Dwellings
Granny flat in Longueville is largely heritage-restricted — HCAs cover most streets. Where compliant siting exists, build cost $290K–$440K including suspended slabs and retaining on harbour-fall lots. Rental yields $800–$1,000/week driven by Tambourine Bay/Woodford Bay outlook.
Practical realities of building a granny flat 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 full granny flat process in Longueville — 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 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. Secondary dwellings on 600–1,400m² blocks deliver rental returns of $650–$900/week per week. CDC approval through a private certifier typically takes 10–15 business days. 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.
Granny flats in Lane Cove deliver $650–$900/week typical, $750–$1,000/week on river/harbour-fall lots in Greenwich and Longueville. Block sizes 500–900m² generally accommodate compliant siting on detached lots. Heritage Conservation Areas restrict placement on Greenwich, Longueville, Northwood and Linley Point peninsulas. Sandstone-dominant soil; suspended slabs and substantial retaining on river-fall lots add $25K–$60K. Tree Preservation Order LGA-wide. Bushfire BAL ratings on bush-edge lots in Lane Cove West and Riverview. CDC available outside heritage zones; otherwise full DA. Realistic build cost $230K–$370K for premium 60m².
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 secondary dwelling, 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 building a granny flat 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 secondary dwellings up to 60m² under the Housing SEPP without DA. Buildana checks every overlay (heritage, bushfire, flood, acid sulfate soil, biodiversity) before quoting.
What a Secondary dwelling Costs in Longueville
Longueville's median house price sits at $3.5M–$7.5M. That's the number that decides whether a granny flat stacks up financially. Build cost $150K–$260K against $650–$900/week in rental — payback period typically 7–11 years, plus capital uplift on the parent lot. 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 secondary dwelling 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 — 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 Longueville
Separate meter is non-negotiable. Without it, rental income gets murky (who pays for electricity?) and lease compliance becomes a fight. Longueville 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.
Rental yield on a Longueville granny flat typically sits around 8–11% gross — often stronger than the main dwelling in percentage terms. The $200K–$260K build returns $18K–$28K per year in gross rent. Even after expenses, it clears comfortably.

How It Works
From First Call to Final Key
Granny flats get underestimated. A lot of builders treat them as a kit-home product. We don't. Your Longueville block has a main dwelling, a driveway, service connections, trees, and neighbours — the secondary dwelling gets designed around those realities.
⏱The 60m² SEPP cap is not a suggestion. Every millimetre gets used — kitchen, bathroom, laundry, living, bedroom, storage — with the envelope tuned for Longueville's sun and prevailing breeze. Real rooms, not compromise spaces.
⏱CDC gets lodged through a private certifier the week design locks in. 10–15 business days later, slab starts. The trades sequence tight because the footprint is small — one plumber, one sparkie, one tiler, one programme.
⏱Handover gives you a genuinely rentable second home. Separate meter, independent hot water, standalone bathroom, full kitchen. Ready to lease on handover day, not a 'studio' that needs another $20K of finishing.
⏱Quality Promise
Our Longueville granny flat builds run on CDC fast-track where eligible. 10–15 business days to approval, 12 weeks to handover, fixed price.
