Duplex & Multi Unit
Builds
Dual-occupancy builds for investors and multi-generational families
Dual-occupancy builds for investors and multi-generational families
Whether you're building a duplex to hold as an investment, sell on completion, or house two generations of the same family on one block, the build needs to work harder on cost control and approvals than a single home does.
We handle the council approval process for dual-occupancy developments from the outset, working through subdivision, easements and dual-key layouts so the finished product performs the way you need it to — as an investment, a family solution, or both.
Every duplex we build is priced and documented as two connected fixed-price contracts, so cost tracking and eventual titling stay clean and simple.
What's Included
- Dual-occupancy and dual-key layout design
- Council approvals and subdivision coordination
- Separate metering and title-ready documentation
- Investment-grade finish specification
- Fixed-price contract across both dwellings
How We
Work Together.
Every Formex Homes project — including this one — runs through the same five stages.
Consultation
We walk your site or block, talk through your brief, budget and timeline — a real conversation, not a questionnaire.
Design
Concept plans and material selections refined together until the design is locked.
Approvals
We manage council and permit approvals, and finalise your fixed-price contract.
Construction
Building begins with scheduled site visits and weekly progress updates.
Handover
Final walkthrough, quality sign-off, and keys handed over with full documentation.
What This
Looks Like.

Detail
InteriorWhat Makes This
Different.
Subdivision-ready from day one
Titling, easements and separate services are planned into the design, not retrofitted after construction.
Investment-grade finish level
Specifications are set to suit resale or rental performance, not just personal preference.
Two contracts, one accountable builder
Each dwelling is priced and tracked separately, but managed under a single point of contact.
We built a duplex as an investment and Formex managed approvals, trades and budget without us having to chase anything.
About This
Service.
In most cases yes — we coordinate subdivision and titling requirements with council as part of the approvals process, though this depends on local zoning.
Yes, separate metering for power, water and gas is standard on our duplex builds unless you specify otherwise.
Shared walls and site costs typically bring the per-square-metre cost down compared to two standalone homes, though total project cost depends on your specific layout.
