A duplex in Five Dock costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, City of Canada Bay Council approvals, construction and subdivision under one fixed-price contract.
Five Dock Dual Occ. — Feasibility to Handover
A duplex in Five Dock is a bet on 2030. That is when Sydney Metro West opens the suburb's own station, and every qualifying block inside walking distance gets repriced. Qualifying is the operative word. Canada Bay's minimum is 600m² and blocks run 450 to 800m², so the Italian-Australian post-war homes on the fuller lots clear it while the tighter Federation streets miss. R3 along Great North Road and Lyons Road opens a denser pathway again.
Even without the Metro the maths worked. $2.0M to $3.8M medians, village retail, and buyer depth for new family homes on both sides of a pair. With it, building now means holding finished product through the repricing instead of paying for it afterwards. Heritage Conservation Areas cover several streets, so that check comes first.
What I would check first on a Five Dock block: whether it clears 600m² or falls under R3, the heritage status, and the walk to the coming Metro. Those set the feasibility.

Building before the 2030 repricing
Sydney Metro West opens Five Dock's own station in 2030, and every qualifying block inside walking distance gets repriced. Building now means holding finished product through that repricing instead of paying for it afterwards.
Qualifying is the operative word: Canada Bay's 600m² minimum against 450 to 800m² blocks means the fuller post-war lots clear it while the tighter Federation streets miss. R3 along Great North Road and Lyons Road opens a denser pathway on some blocks.
The maths worked before the Metro
Even without the station the case held: $2.0M to $3.8M medians, village retail, and buyer depth for new family homes on both sides of a pair. The Metro just adds a repricing on top.
Heritage Conservation Areas cover several streets, so that check comes first. Send us the address and we will confirm the size, the zoning and the heritage together.

How It Works
From First Call to Final Key
We assess your Five Dock block — lot size (typical 450–800m²), width, R2 Low zoning, setbacks, FSR, landscaped area requirements under City of Canada Bay Council's LEP and DCP. Minimum lot for duplex: 600m².
⏱Design phase covers unit layout, access, parking, private open space, and waste management for dual occupancy on your Five Dock site. You approve final plans before we move to lodgement.
⏱Duplex approvals get scrutinised harder than single dwellings — neighbour notification, overshadowing, privacy, traffic, waste. Our SEE addresses each on the front foot rather than reactively.
⏱Fixed-price construction of both dwellings from slab to keys. Class M–H engineered footings, frame, lock-up, internal fit-out, and external works.
⏱Subdivision registration starts in parallel with final fitout so titles issue close to handover, not 6 months after. Buildana coordinates the surveyor and City of Canada Bay Council clearance — important if you're planning to sell one side immediately to fund the next move.
⏱Quality Promise
We build duplexes in Five Dock end-to-end — feasibility, design, DA/CDC, dual-slab construction, subdivision. One contract.
