A duplex in Abbotsford 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.
Abbotsford Dual Occ. — Feasibility to Handover
A duplex in Abbotsford depends entirely on heritage, because Conservation Areas cover several streets on this Federation river peninsula. On an eligible non-heritage lot clearing the Canada Bay 600m2 minimum a dual-occupancy is feasible, but on a contributory property the honest answer is a single sympathetic home, not a duplex. The premium river setting also means a single high-end residence often beats splitting the block.
The ground is Wianamatta Shale with sandstone outcrops, so footings are engineered off geotech to suit, and on a sloping river-fall lot the design steps with the fall. Heritage status decides feasibility first, and I would rather tell you up front whether your block is a duplex site or a single-home one. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Abbotsford block: the heritage status, whether the lot clears the 600m2 minimum, and the river fall. Those decide dual-occ versus single.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you honestly whether it is a duplex site.

Heritage decides feasibility
Conservation Areas cover several streets on this Federation river peninsula, so on a contributory property a single sympathetic home is the honest answer.
On an eligible non-heritage lot clearing the Canada Bay 600m2 minimum a Torrens-title duplex is feasible.
River fall and shale
The ground is Wianamatta Shale with sandstone outcrops, so footings are engineered off geotech to suit.
On a sloping river-fall lot the design steps with the fall, with older fibro stripped under licence first.

How It Works
From First Call to Final Key
Site visit, title search, and planning assessment for your Abbotsford block. We check lot dimensions against City of Canada Bay Council's minimum (600m²), review overlays, drainage, access, and services. You get a clear yes/no on duplex feasibility plus estimated yield.
⏱Design has to satisfy four audiences at once: City of Canada Bay Council, the future buyer or tenant, the certifier, and you. Each pull in a different direction — our job is to land plans that work for all four. Solar access, privacy, parking, POS, FSR, all balanced.
⏱We lodge and chase your approval — DA through City of Canada Bay Council for most duplexes, or CDC where eligible. R2 Low zoning in Abbotsford. CC issued, conditions cleared, ready to build.
⏱Building both sides in parallel halves the loan interest holding cost vs sequential builds. Bulk material orders for cabinetry, tiles, fixtures cut unit cost. Single site setup, single supervisor, single insurance period — efficiency compounds across the whole programme.
⏱Strata or Torrens title subdivision completed. Separate OCs, individual metering, 6-year structural warranty per dwelling. Strong rental demand near Drummoyne ferry / North Strathfield (3 km).
