Duplex estimates turn on the lot and the exit strategy more than on finishes. Share what you can from this list and the response can address pathway, configuration and construction scope together rather than in fragments.
Checklist
Include this with your enquiry
The property address, so zoning, lot dimensions and overlays can be verified
Whether the lot is vacant or carries an existing house, and if so its age and construction
Your intended outcome: hold both, sell one, sell both, or house family across the pair
Any survey, contract for sale, or title documents you already hold
Preferences on attached versus detached form, storeys and bedrooms per dwelling
Timing pressures: settlement dates, tenancy plans or family milestones
What happens next
After you send it
Duplex Builder Sydney is a service-matching website operated by Jordan James Media, not a building company. Once matching opens for your region, your enquiry is forwarded to the appointed licensed builder for dual occupancy work in that area, and every contractual, licensing and insurance obligation for the project sits with that builder, whose credentials you can verify directly.
Dual occupancy construction is residential building work under NSW law: it requires a contractor licence issued by NSW Fair Trading, written contracts in the prescribed form, and home building compensation cover for contracts above the statutory threshold before any deposit changes hands. Verify licences on the official register, and route subdivision, title and contract questions to registered surveyors and qualified legal advisers.
