Quick Answer
A granny flat in Lane Cove West 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.
Lane Cove West Secondary Dwellings
A granny flat builder in Lane Cove West works with large river-fall blocks where a secondary dwelling is about family or premium rental. The Federation and contemporary stock sits on 600 to 1,200m² blocks along the Lane Cove River, so clearing the 450m² threshold for a 60m² secondary dwelling under the Housing SEPP is never the issue. Heritage Conservation Areas, the river fall and bushfire on the bush-edge lots shape the build.
The sandstone-dominant ground behaves for the slab off geotech, though the substantial fall to the river can add engineering and rock excavation. Bush-edge lots backing Lane Cove National Park carry a BAL rating the granny flat has to meet. Where the older home has fibro, a licensed asbestos strip-out comes first if demolition is involved.
What I check first on your Lane Cove West block: whether you sit inside a Heritage Conservation Area or on a bushfire-rated bush-edge lot, the river fall and rock, and the rear-yard access. Those decide the build.

Large blocks, layered constraints
Lane Cove West's 600 to 1,200m² river-fall blocks clear the 450m² Housing SEPP threshold easily, so land size never stops a granny flat here. What shapes the build is the layering of constraints: Heritage Conservation Areas over several streets, substantial fall to the Lane Cove River, and bushfire on the lots backing Lane Cove National Park. Each has to be mapped on your specific block.
A granny flat here is usually about extended family living or a premium rental given the river setting, so the value is in building it well and, where the block allows, taking the outlook.
River fall, rock and bushfire
The sandstone ground behaves for the slab off geotech, but the fall to the river can add engineering and rock excavation, which on a small granny flat footprint is proportionally large. Bush-edge lots also carry a BAL rating that the secondary dwelling must meet. I price the fall, the rock and any bushfire spec from real assessments rather than a guess, so a Lane Cove West granny flat builds predictably.

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 Lane Cove West 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 Lane Cove West'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 Lane Cove West granny flat builds run on CDC fast-track where eligible. 10–15 business days to approval, 12 weeks to handover, fixed price.
