A duplex in Wareemba 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.
Dual Occupancy Developments in Wareemba
A duplex in Wareemba works on the larger non-heritage blocks in a tightly held inland pocket between Abbotsford and Five Dock. Lots run 450 to 700m2, so the larger ones clear the 600m2 Canada Bay duplex minimum and the smaller fall short. On a $2.0M to $3.8M market, a quality Torrens-title duplex can work, but Heritage Conservation Areas cover several streets and shape a lot of the stock.
The ground is Wianamatta Shale, moderately to highly reactive, so footings and the slab are engineered to suit across both dwellings. The Federation and inter-war stock carries asbestos, stripped under licence first, and the heritage streets are checked before any design.
What I would check first on your Wareemba block: the heritage status and the area against 600m2, then the frontage for two dwellings.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you honestly what it carries.
Buildana manages the full duplex development process in Wareemba — 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.

Larger non-heritage blocks qualify
Wareemba lots run 450 to 700m2, so the larger ones clear the 600m2 Canada Bay minimum.
It is a tightly held inland pocket between Abbotsford and Five Dock, with steady demand at $2.0M to $3.8M.
Heritage and reactive shale
Heritage Conservation Areas cover several streets, checked before design.
The Wianamatta Shale means footings and slab engineered to suit, and older stock stripped of asbestos under licence.

How It Works
From First Call to Final Key
We assess your Wareemba block — lot size (typical 450–700m²), 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 Wareemba 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.
