A duplex in Cabarita 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.
Building Duplexes in Cabarita
A duplex in Cabarita works on the larger lots that clear the Canada Bay 600m2 minimum and sit off the heritage streets, though the premium river outlook often favours a single home. This riverside peninsula runs Federation cottages, inter-war heritage and contemporary on 500 to 1,000m2 blocks with fall to the Parramatta River, and at a $2.5M to $5M market a dual-occupancy is feasible on a qualifying lot but a single premium residence sometimes returns more. Heritage Conservation Areas cover several streets, so the status check comes first.
The ground is Wianamatta Shale, so footings get stable bearing and a slab off geotech is routine on both dwellings, with the fall to the river handled in the siting. On a qualifying non-heritage lot a side-by-side works cleanly. Where older homes carry fibro a licensed asbestos strip-out comes first.
What I would check first on your Cabarita block: whether it clears the 600m2 minimum, the heritage status, and whether a duplex or a single river-outlook home returns more. Those set the best use.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you the best use of the block.

Feasibility against 600m2
This riverside peninsula runs Federation, inter-war and contemporary stock on 500 to 1,000m2 blocks, so the larger lots clear the Canada Bay 600m2 minimum.
At a $2.5M to $5M market a dual-occupancy is feasible on a qualifying lot, though the premium river outlook sometimes favours a single home.
Stable ground, river fall
The Wianamatta Shale gives footings stable bearing, so a slab off geotech is routine on both dwellings.
Heritage sits on several streets, so the status check comes first, with older fibro stripped under licence.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Cabarita block — lot size (typical 500–1,000m²), width, R2 Low zoning, setbacks, FSR, landscaped area requirements under City of Canada Bay Council's LEP and DCP. Minimum lot for duplex: 600m². You'll know viability before spending on design. Design phase covers unit layout, access, parking, private open space, and waste management for dual occupancy on your Cabarita site. You approve final plans before we move to lodgement.
⏱The Cabarita construction phase. Fixed price, programmed, supervised. 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. Cleaner submission, fewer conditions, faster CC. Fixed-price construction of both dwellings from slab to keys. Class M–H engineered footings, frame, lock-up, internal fit-out, and external works. Weekly progress reports.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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
Our Cabarita duplex projects run from feasibility to subdivision under one builder. Fixed price, dual handover, full compliance.
