Let me be straight about a duplex in Cammeray: it is rarely on the table. North Sydney Council heavily restricts dual-occupancy, the blocks are tight at 300 to 550m², and Heritage Conservation Areas cover several streets of Federation and inter-war stock, so a standard duplex almost never stacks up here. Honesty about that saves you money before you engage a designer.
Where anything is possible on a rare block, it is a premium, heritage-sensitive exercise rather than a standard dual-occupancy, and the ridge setting between Long Bay and Tunks Park shapes the engineering. For most owners at a $2.6M to $3.8M median, a single well-designed home suits the controls and the Miller Street village character far better. We tell you plainly what your block allows.
What I would check first on your Cammeray block: whether dual-occupancy is even permissible under the North Sydney controls, the heritage status, and the block size. Those decide whether a duplex is possible.
We build these fixed-price, licence HBL 487805C. Let us check your block's controls before you plan.
Buildana manages the full duplex development process in Cammeray — from feasibility assessment and architectural design through to DA or CDC approval, and fixed-price construction to dual handover. One builder, one contract, two homes.

Rarely on the table
North Sydney Council heavily restricts dual-occupancy, the blocks are tight at 300 to 550m², and Heritage Conservation Areas cover several streets of Federation and inter-war stock.
So a standard duplex almost never stacks up here, and honesty about that saves you money before you engage a designer.
What suits instead
On a rare permissible block, it is a premium, heritage-sensitive exercise rather than a standard dual-occupancy.
For most owners at a $2.6M to $3.8M median, a single well-designed home suits the controls and the Miller Street village character far better.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Quick desktop check first — lot size, zoning, frontage — then full site visit if it stacks. Drainage path, neighbour overlooking, slope, services, easements. 500m² minimum is just the entry ticket; the real feasibility is whether two compliant dwellings actually fit and sell. Our architect designs both dwellings to maximise your Cammeray block's yield — floor plans, elevations, 3D renders, and landscape concept. We optimise for rental return and sale value under North Sydney Council's DCP.
⏱The Cammeray construction phase. Fixed price, programmed, supervised. Most Cammeray duplexes go DA route through North Sydney 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.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspections, dual OCs issued, subdivision registered with LRS. Each dwelling gets its own title, services, and 6-year structural warranty. Ready to rent, sell, or occupy.
