Duplex Kurraba Point — Feasibility, Design, Approval & Build
End-to-end duplex delivery in Kurraba Point 2089: yield analysis, design for R3 Medium zoning, North Sydney Council approvals, subdivision coordination, construction, separate services and handover.
Quick Answer
A duplex in Kurraba Point costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, North Sydney Council approvals, construction and subdivision under one fixed-price contract.
Kurraba Point Duplex Construction
A duplex in Kurraba Point is rarely the play, because this premium harbourside peninsula carries heavy heritage controls that favour a single home. The Federation and inter-war stock sits on 300 to 600m2 blocks with substantial fall to the water, and heritage controls are heavy across the peninsula, so a dual-occupancy is constrained or precluded on contributory lots. At a $3.2M to $6.5M market a single premium residence usually returns more than splitting a block.
The sandstone soil and harbour fall mean engineered slabs and retaining are standard, so a duplex would double that on a premium market that rewards one home. I would rather give you the honest read than push the wrong product. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Kurraba Point block: the heritage status, whether a single premium home is the clear best use, and the harbour-fall retaining. That decides the direction.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you honestly what the block suits.

Premium harbour, heavy heritage
The Federation and inter-war stock sits on 300 to 600m2 blocks with substantial fall to the water.
Heritage controls are heavy, so a dual-occupancy is constrained or precluded on contributory lots, at a $3.2M to $6.5M market.
Harbour-fall retaining
The sandstone soil and harbour fall mean engineered slabs and retaining are standard.
A duplex would double that on a market that rewards a single home, with older fibro stripped under licence first.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Feasibility covers the planning side and the financial side. Yes-or-no on whether the block supports dual occupancy under North Sydney Council controls, plus indicative end values, build cost, and likely yield. The point is to kill bad sites before you spend on design — not after. Dual occupancy floor plans designed for your Kurraba Point block — attached or detached configuration, vehicle access, private open space, and full North Sydney Council compliance.
⏱The Kurraba Point construction phase. Fixed price, programmed, supervised. Full approval management: Statement of Environmental Effects, plans, reports, and all supporting documentation lodged with North Sydney Council or private certifier. We handle RFIs and conditions. CC follows. Construction follows a tight programme: dual slabs in one mobilisation, paired frame stand, simultaneous lock-up, then trades rotate between sides for fit-out so no day is lost waiting on availability. The schedule is engineered, not optimistic.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Both dwellings handed over with individual Occupation Certificates. Subdivision lodged for separate titles. Separate metering installed. 6-year structural warranty per dwelling.
