Building a duplex home is becoming an increasingly popular choice for homeowners, investors and multi-generational families across Sydney and the Illawarra. Whether your goal is to maximise the value of your land, create space for extended family, or generate rental income, a duplex can be a smart and flexible solution.
At Crystele Homes, we offer a range of thoughtfully designed duplex and dual living home designs, with customisation options available to suit your block, budget and lifestyle requirements.
Our dual living home designs provide separate living spaces under one roof — offering privacy, independence and convenience, without sacrificing comfort or style.
What Is a Duplex Home?
A duplex typically consists of two separate dwellings on one block of land, each with its own entry, kitchen, living areas, bedrooms and amenities. The two homes are usually side-by-side (or sometimes one above the other), sharing a common wall but operating as completely independent residences.
Duplex homes are commonly built to:
- Live in one dwelling and rent the other
- House multiple generations of a family
- Maximise resale value and land use
- Create dual income investment opportunities
Duplex & Dual Living Designs at Crystele Homes
Crystele Homes offers duplex and dual living designs across both of our design collections — Classic and Creative — allowing you to choose the level of inclusions, flexibility and budget that best suits your project.
Our two Classic Collection duplex and dual living designs available are:
- Lachlan & GF – dual living
- Clifton – Duplex design
Our Classic Collection duplex designs offer a higher level of inclusions as standard, along with the freedom for full customisation. These designs are ideal if you’re looking for premium finishes, architectural flexibility, or a tailored solution for a specific site.
Creative Collection duplex designs include:
- Donovan
- Ironstone
- Peridot
- Rose
If you’re working with a smaller lot or a defined budget, our Creative Collection duplex designs are cleverly planned to maximise space and comfort. These homes feature smart layouts with optional upgrade packages to streamline the build process.
Each design has been carefully developed to deliver functionality, liveability and long-term value.
What are the benefits of building a duplex?
1. More Value from One Block
A duplex allows you to build two homes on a single block, often resulting in higher resale value and stronger long-term returns compared to a single dwelling.
2. Ideal for Multi-Generational Living
Duplex homes are perfect for families wanting to live close — but independently. For example:
- Parents in one dwelling, adult children in the other
- A family in one home, grandparents in the second
- Close support while maintaining privacy
3. Rental Income Potential
A duplex offers flexibility when it comes to income:
- Live in one home and rent the other
- Rent both dwellings for dual income
- Offset your mortgage while staying in your own home
This makes duplexes appealing for both owner-occupiers and investors.
Frequently Asked Questions
What is the difference between a duplex and a dual living design?
A duplex typically consists of two equal, fully independent dwellings on one title.
A dual living design usually includes one main home with a smaller secondary dwelling — such as an attached granny flat or a separate living zone within the same structure.
Both options offer flexibility, but the best choice depends on your block, council requirements and intended use.
Do you customise your duplex designs?
Yes. Classic Collection duplex designs can be customised to suit your block, layout preferences and lifestyle needs. Our team works closely with you to tailor the design while ensuring compliance with planning controls.
Do you offer pools and landscaping with duplex builds?
Yes. Crystele Homes can include pool and landscaping services as part of your duplex build, offering a streamlined process with one builder, one contract and one timeframe.
Have you built duplex homes before?
Yes. Crystele Homes has built a wide range of duplex and dual living homes across Sydney and the Illawarra, giving us the experience and expertise needed to navigate planning requirements and site conditions.
Does it take longer to build a duplex?
A duplex can take slightly longer than a single dwelling due to its size and complexity. However, with proper planning and an experienced builder, timelines can be managed efficiently.

We build duplex and dual living homes across Sydney and the Illawarra region, subject to local planning controls and site suitability.
