Quick Answer
A duplex in Lane Cove North costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Lane Cove Council approvals, construction and subdivision under one fixed-price contract.
Dual Occupancy Developments in Lane Cove North
A duplex in Lane Cove North is a strong dual-occupancy play with genuine higher-density upside near the Metro. The Federation, inter-war and post-war stock sits on 500 to 800m² blocks, so most clear the dual-occupancy minimum for a Torrens-title duplex, while the R3 and R4 redevelopment around Mowbray Road and the Crows Nest Metro precinct opens an apartment yield on the right block. The 2024 Metro TOD overlay reaches the south-eastern portion.
The sandstone ridge ground behaves for slab and footings once geotech is in, with rock excavation possible on the higher parcels. Where an older home carries fibro, a licensed asbestos strip-out leads the demolition.
What I check first on your Lane Cove North block: whether you sit inside the Crows Nest Metro TOD precinct where higher density applies, the R3 or R4 layer, and the depth to sandstone. Those decide the best use of the land.

The Metro changes the calculation
Lane Cove North's south-eastern portion falls inside the 2024 Crows Nest Metro TOD precinct, and around Mowbray Road the R3 and R4 zoning already supports medium-density. On those blocks an apartment or townhouse yield can far exceed a straight duplex, and building a duplex there could leave real value on the table. Away from the precinct, a Torrens-title duplex on a 500 to 800m² block is the clean play.
This is why the location of your specific block matters so much here. Two streets apart can mean two completely different best uses, and I would rather map that against the overlays than guess.
Sandstone ridge and rock
The Lane Cove North ridge is sandstone, so the higher parcels can carry rock excavation for the two slabs. Priced from a real geotech rather than assumed, it becomes a known line in the budget. The ground is otherwise stable for a dual occupancy. Get the overlays and geotech checked early and the build runs predictably.

How It Works
From First Call to Final Key
Quick desktop check first — lot size, zoning, frontage — then full site visit if it stacks. Drainage path, neighbour overlooking, slope, services, easements.
⏱Our architect designs both dwellings to maximise your Lane Cove North block's yield — floor plans, elevations, 3D renders, and landscape concept. We optimise for rental return and sale value under Lane Cove Council's DCP.
⏱Most Lane Cove North duplexes go DA route through Lane Cove Council — CDC pathways for dual occupancy are restrictive on most R2 blocks. We pre-meet with council planners on borderline sites to confirm support before lodgement, which avoids a 3-month round trip on RFIs.
⏱Both dwellings built simultaneously — engineered slabs (Class M soil), frame, lock-up, fit-out. Milestone updates from your project manager.
⏱Final inspections, dual OCs issued, subdivision registered with LRS. Each dwelling gets its own title, services, and 6-year structural warranty.
⏱Quality Promise
Buildana delivers Lane Cove North duplexes as a single project — one contractor accountable from site check to subdivision.
