Lane Cove North Granny Flat Construction — Fixed Price
A granny flat builder in Lane Cove North works with the pocket bordering Willoughby at Artarmon and Chatswood — Federation, inter-war and post-war detached on 500 to 800m² blocks, alongside significant R3 and R4 redevelopment around Mowbray Road and the St Leonards and Crows Nest Metro precincts. The detached side-street blocks clear the 450m² Housing SEPP threshold comfortably, so a 60m² secondary dwelling works well, and with Artarmon and the new Metro close, a studio lets easily.
The Metro-precinct streets are being redeveloped to R3 and R4 density, so on those a secondary dwelling isn't the highest use — it suits the settled detached blocks away from the TOD overlay. Heritage is lighter here than the harbour suburbs, but I still check your specific street.
The soil grades sandstone on the ridge, so the slab is conventional and engineered off a geotech. The post-war stock can carry fibro, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. Zoning and soil scoped first.

Detached blocks, Metro-close
Lane Cove North's detached side-street blocks of 500 to 800m² clear the 450m² Housing SEPP threshold comfortably, so a 60m² secondary dwelling works well.
With Artarmon and the new Crows Nest Metro close, a studio lets easily on a qualifying block.
TOD overlay and soil
The Mowbray Road and Metro-precinct streets are being redeveloped to R3 and R4 density, so a secondary dwelling suits the settled detached blocks away from the TOD overlay.
The sandstone ridge keeps the slab conventional off a geotech, and post-war stock can carry fibro.

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 North 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 North'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.
