Duplex
Two homes.
One easy decision.
A smarter way to get more from your land.
A duplex gives you flexibility, choice and the chance to unlock real potential from a single block. Whether you’re looking to create two homes for family, build an income-generating investment, or simply make the most of your land, a duplex is one of the most efficient and future-focused ways to build in NSW. With clear pathways and the ability to subdivide once complete, a duplex offers all the freedom of two homes, wrapped into one smart solution.
Expertly guided from the very first step
NSW planning changes have unlocked the opportunity to increase the value of your property by building a duplex, however the complexity can be overwhelming. At Rawson our experts manage the entire process. From feasibility to subdivision - handled. You enjoy the outcome.
Free site assessments
Before you invest a cent, we start with a complimentary site assessment to understand your block’s potential. We look at zoning, access, slope, services and the likely approval pathway so you know upfront whether a duplex is the right fit.
Internal compliance reviews
Every duplex is thoughtfully designed to meet NSW planning rules and local council requirements, without losing focus on functionality, style, and lasting value for both dwellings.
Relevant title & planning checks
From day one, we ensure your duplex is feasible, and set up for success—identifying opportunities and challenges early so you can move ahead with confidence.

Simple 6-step duplex build process
A guided, managed pathway from first site check through to subdivision and handover.
1. Free Site Assessment
Before you invest a cent, we start with a complimentary site assessment to understand your block’s potential.
We look at zoning, access, slope, services and the likely approval pathway so you know upfront whether a duplex is the right fit.
2. Permissibility Check
For a one-off $5,000 fee, a permissibility check is completed to assess CDC/DA feasibility, including internal compliance checks, borehole and contour surveys.
You get a clear picture of what’s possible before committing to the full build.
3. Tender and Contract
We prepare your tender, including site costs, subdivision requirements, and selections that are tailored to your needs.
Once you’ve accepted your tender, building contracts will be prepared for you to sign prior to lodging CDC/DA approval.
4. Council or Certifier Approval
Whether your project goes through DA or CDC, we manage the entire approval process for you.
From preparing documentation to coordinating engineers, consultants and certifiers, our team will guide you through the process.
5. Construction & Quality Assurance
Once approved, your duplex is brought to life by our experienced construction team.
We keep you informed throughout the build, and every stage is independently quality checked – so you can move forward knowing your new home is built to the highest standard.
6. Subdivision & Handover
At completion, we handle the final stage of your subdivision and ensure your home meets regulatory requirements.
Then, we hand over your brand-new duplex, ready for living, leasing or selling with complete confidence.

These inspections typically occur at the slab, frame, and final completion stages, ensuring that both the structural integrity and finishing quality of your home are thoroughly assessed. Because they are conducted by independent inspectors, they provide an added layer of impartial oversight and reassurance that your home meets required standards throughout the build.
