A duplex builder Gold Coast owners can talk to directly
A duplex can do a lot of work for your family. Live in one side and rent the other. Build both as an investment. Make room for parents or grown-up children with their own space. Or replace an older house with two new homes on the same block.
As a duplex builder on the Gold Coast since 2004, we design and build duplexes and dual living homes Built To Requirement™, planned around your block, your goals and the rules that apply to your site.

How building a duplex works
Working with your duplex builder Gold Coast team follows four clear stages, so you know what your site can support before you invest in detailed plans.

Duplex options we build
Live in one, rent the other
Owner-occupy one side and rent or sell the other. A well-planned duplex can help with the cost of building while giving you a brand-new home to live in.
Dual occupancy for investors
Two dwellings designed for durability, low maintenance and appeal to tenants or buyers. We’ll help you balance design, inclusions and build cost so the numbers make sense for your investment.
Knockdown to duplex
If your existing house is past its best but your block is in the right spot, a knockdown rebuild to a duplex can make the most of your land. We’ll help you understand what’s involved before you commit.
Dual key and dual living homes
One home with a separate self-contained living area, ideal for multi-generational families, older children or guests. Read our guide to dual living home designs for ideas.
What to check before you build a duplex
Whether a duplex is possible, and what it will cost, depends on your site. The City of Gold Coast, Logan and Brisbane each have their own rules for duplexes and dual occupancy, covering things like lot size, frontage, setbacks and parking.
Your goals matter too. Living in one side, renting both or selling one will shape the layout, inclusions and budget. Your Core Feasibility Assessment covers these considerations up front, so you can decide with confidence before investing in detailed plans. Our guide to the cost to build a custom home explains more about what drives the price.
Your duplex site checklist
- Zoning and council requirements for your lot
- Lot size, frontage and setbacks
- Slope, soil, drainage and flood or other overlays
- Separate water, sewer, power and stormwater for each dwelling
- Parking and access for both homes
Duplex or dual living home?
Duplex
- Two separate dwellings on one block
- Each with its own entry, kitchen and facilities
- Suits investors, or living in one and renting the other
- Usually needs more involved approvals and separate services
Dual living home
- One home with a separate self-contained living area
- Often under a single roof
- Suits multi-generational families, older children or guests
- Can suit blocks where a full duplex isn’t possible
Choosing a duplex builder Gold Coast investors can rely on
A duplex has more moving parts than a single home: two sets of services, more involved approvals and two dwellings that both need to work well. That’s why choosing a duplex builder Gold Coast investors and families can deal with directly matters. We’re a small, local team, so you’ll speak with the people who estimate, plan and build your project, and we’re proud members of Master Builders Queensland.
We start by checking what your site can support, then design both dwellings around your goals. If you’re comparing builders, ask each one how they price site works and separate services, what’s included as standard and who you’ll deal with during construction.

Duplex Builder Gold Coast FAQs
Can I build a duplex on my block?
It depends on your zoning, lot size, frontage and other site conditions, which vary between councils and suburbs. Send us your address and we’ll check what may be possible as part of your free Core Feasibility Assessment.
How much does a duplex cost to build?
Every duplex is different. Size, design, inclusions and site conditions all affect the price. Your Core Feasibility Assessment gives you an estimated investment range for your specific project before you commit.
Can you build a duplex after a knockdown?
Yes. Replacing an older home with a new duplex is a common way to make the most of a well-located block. We’ll help you understand demolition, approvals and site requirements as part of planning your project.
Can I live in one side and rent the other?
Yes, and it’s one of the most popular reasons to build a duplex. We’ll design each side around how it will be used, so your home suits you and the other dwelling appeals to tenants. Talk to your accountant or financial adviser about how this works for your situation.
What areas do you build duplexes in?
We build across the Gold Coast, Logan and selected Brisbane suburbs. Use our Find a Builder search to confirm your area.
