Canada Bay wants 600m² for a duplex, and Drummoyne blocks run 350 to 700m², so the suburb splits cleanly into haves and have-nots. The 350m² Federation lots near the peninsula tip were never candidates. The 600 to 700m² blocks on the wider streets are, and corner positions among them are the prize: dual street frontage solves the driveway and entry problems that make mid-block dual occupancy feel like a compromise.
The economics justify the hunt. Medians at $2.5M to $6M with harbour outlook and ferry access mean each side of a well-designed pair holds serious end value. This close to the city, qualifying land is the scarce ingredient, not buyer demand. Heritage Conservation Areas cover several streets including parts of the Lyons Road peninsula, so the overlay check comes first.
What I would check first on a Drummoyne block: whether it clears 600m², whether it is a corner with dual frontage, and the heritage overlay. Those decide it.

Haves and have-nots
Canada Bay's 600m² duplex minimum against Drummoyne's 350 to 700m² blocks splits the suburb cleanly. The 350m² Federation lots near the peninsula tip were never candidates, and the 600 to 700m² blocks on the wider streets are.
Corner positions among them are the prize, because dual street frontage solves the driveway and entry problems that make mid-block dual occupancy feel like a compromise.
Qualifying land is the scarce ingredient
At $2.5M to $6M medians with harbour outlook and ferry access, each side of a well-designed pair holds serious end value. This close to the city, qualifying land is the scarce ingredient, not buyer demand.
Heritage Conservation Areas cover several streets including parts of the Lyons Road peninsula, so the overlay check comes first. Send the address and we will tell you if your block is one of the haves.

Drummoyne dual occupancy construction: feasibility assessment first, then fixed-price build to dual handover. No surprises.
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. 600m² 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 Drummoyne block's yield — floor plans, elevations, 3D renders, and landscape concept. We optimise for rental return and sale value under City of Canada Bay Council's DCP.
⏱Most Drummoyne duplexes go DA route through City of Canada Bay 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–H 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. Ready to rent, sell, or occupy.
