Who it suits

A duplex is a decision about land, not just a house.

  • 01

    Live in one, rent the other

    A home for your family and an income from the second dwelling, on land you already own.

  • 02

    Investors and first-time developers

    Two new homes from a single block, designed for the people who will live in or rent them.

  • 03

    Multi-generational families

    Parents next door, not across town. Two independent homes with one shared street frontage.

  • 04

    Knockdown and rebuild

    Replace a tired house with a duplex on the block you love. Demolition, approvals and construction handled together.

Site assessment

What we check before anyone draws a line.

Not every block suits a duplex. The desktop feasibility is free and tells you early.

A completed Morris Homes duplex at Blue Bay: two timber front doors behind one cohesive facade

  1. 01

    Your site address and survey

    Lot width, depth, slope and orientation decide which plans fit. We start with a free desktop feasibility.

  2. 02

    Council and NSW planning controls

    Each property is checked individually against current controls. Duplex eligibility is confirmed per site, never promised by suburb.

  3. 03

    Services and access

    Stormwater, sewer, driveway crossovers and street trees all shape the design and the budget.

  4. 04

    Your budget

    Established at the start. The design, structure and selections are then engineered to meet it.

Duplex designs

6 plans, six to ten bedrooms in total.

FAQs

Duplex questions, answered straight.

How do you work to a budget?
We establish the budget at the very start, before design. A free desktop feasibility checks the site, then preliminary drawings are costed with real trade take-offs and bills of quantities. We only sign a HIA fixed price contract once plans, selections and approvals are complete.
Do you have base prices?
No. Every duplex or custom home is priced on its own site, design and selections, so we do not publish base prices. Book a discovery session and we will talk through a realistic range for your project.
Can you tell me if my block suits a duplex?
We assess each property individually against current NSW and council planning controls using your site address, lot dimensions and survey. Feasibility is confirmed per site, not promised by suburb.
How long does a build take?
It depends on council planning and approvals, the size and complexity of the design, site challenges and weather. The estimate and tender stage sets a realistic program for your project.
What inclusions do you offer?
Our current inclusions package is the Coastal Collection. Selections are finalised with Maree from the Client Selections Handbook before contract so there are no surprises during construction.
