A duplex in Breakfast Point 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.
Breakfast Point Dual Occ. — Feasibility to Handover
A duplex in Breakfast Point is not really the product, because this is a master-planned waterfront estate of townhouses and apartments on strata blocks, not freestanding dual-occupancy lots. The suburb was built from the 2000s on the former Mortlake Gasworks site, and the estate is R3 and R4 master-planned with strict controls, so a Torrens-title duplex on a freestanding lot is very unlikely. I would rather be straight about that than pretend otherwise.
On the rare freestanding title a designed home may be possible under the estate controls, but a duplex splitting a block does not fit the master-planned framework. The ground is Wianamatta Shale, engineered off geotech. If you are after dual-occupancy yield, neighbouring Mortlake or Cabarita with genuine R2 lots make far more sense, and I will point you to them.
What I would check first at Breakfast Point: whether any freestanding duplex-capable lot exists at all, which is very unlikely, and the better dual-occ options nearby. That is the honest starting point.
We build these fixed-price, licence HBL 487805C. Tell me what you are after and I will point you to where a duplex actually works.

A master-planned strata estate
This waterfront estate was built from the 2000s as townhouses and apartments on strata blocks, not freestanding dual-occupancy lots.
The R3 and R4 master-planned controls make a Torrens-title duplex on a freestanding lot very unlikely.

How It Works
From First Call to Final Key
Free feasibility check on your Breakfast Point block. We measure frontage width, confirm zoning (R3/R4 master-planned), check minimum lot size against 600m² requirement, and review City of Canada Bay Council's DCP controls. Written feasibility report within 5 business days.
⏱Two dwellings, one site — design is mostly about geometry. Frontage split, party wall position, garage stacking, private courtyard size, and the streetscape elevation a certifier will actually approve. We work the design until both sides feel like proper homes, not mirror-image apartments.
⏱DA through City of Canada Bay Council (40–90 days) or CDC (10–15 business days). Breakfast Point is zoned R3/R4 master-planned. Construction Certificate obtained before works commence.
⏱Dual construction runs 9–14 months. Engineered slabs sized for Class M–H soil, simultaneous frame-up, staggered fit-out for efficiency. Your project manager coordinates all trades and inspections.
⏱Two homes, two titles, two OCs, two warranty packs. We hand over a clean documentation set per dwelling: certifier reports, BASIX certs, structural sign-offs, appliance warranties, maintenance schedules. Whatever the next owner or buyer asks for is in the file.
⏱Quality Promise
Our Breakfast Point duplex projects run from feasibility to subdivision under one builder. Fixed price, dual handover, full compliance.
