FAQs
What are the benefits of choosing a duplex home design in Brisbane?
A duplex offers the perfect mix of flexibility, value and practicality—especially in a growing city like Brisbane. Whether you’re looking to keep family close while maintaining separate living spaces, create a long-term rental opportunity, or simply maximise the potential of your block, a duplex lets you do more with what you have. It’s also a great option for sloping sites or narrow blocks, and with Brisbane’s lifestyle-focused climate, you can enjoy light-filled interiors, private outdoor zones and designs tailored for comfort on both sides of the home.
Can I customise my duplex home design?
Absolutely. Our duplex home designs in QLD are just a starting point, not a finish line. Whether it’s tweaking the layout, adding rooms, or adding those precious personal touches, we’ll help customise the plan to suit your goals, your block and your style. That’s the beauty of building with G.J. Gardner Homes.
Are your designs available across Brisbane?
Yes. G.J. Gardner builds homes right across Brisbane, from Inner City West, to Bayside, Northside, Southside and beyond. Our range of house designs is adapted to suit zoning regulations, local council requirements, block sizes, and lifestyle needs unique to Brisbane.
Can each side of a duplex have a different layout or finish?
Yes, it can. If you’re building to live in one and rent the other, or have different needs for each residence, we can work with you to design two distinct floor plans or vary the finishes. You’ll still benefit from a cohesive external look, but inside, each home can feel uniquely tailored.
Do your homes accommodate Queensland’s tropical and subtropical climates?
They sure do. Our Queensland house designs prioritise natural ventilation, sun protection and thermal efficiency—especially important in tropical and subtropical regions. We consider orientation, airflow and materials to help keep your home comfortable year-round.
