A duplex in Cremorne 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.
Cremorne Duplex Construction
A duplex in Cremorne is uncommon, because this lower-north-shore ridge is mostly apartments and townhouses, with detached homes on premium side-street lots. The Military Road spine runs through, and the stock is largely 1960s to 2000s apartments with pockets of Federation and inter-war detached on 350 to 600m2 side streets. On a rare qualifying detached lot a duplex can work, but the premium market and North Sydney's density focus often mean a single home or a townhouse scheme is the better play.
The ground is engineered off geotech, and heritage sits on some side streets, so the status check comes first. I would rather give you the honest read on whether your lot suits a duplex, a single home or a townhouse than push the wrong product. Where older homes carry fibro a licensed asbestos strip-out comes first.
What I would check first on your Cremorne block: the heritage status, whether the lot is a genuine detached duplex site, and the premium-market economics. That decides the direction.

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 Cremorne block — attached or detached configuration, vehicle access, private open space, and full North Sydney Council compliance.
⏱The Cremorne 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.
⏱Quality Promise
Our Cremorne duplex projects run from feasibility to subdivision under one builder. Fixed price, dual handover, full compliance.
