With Brisbane’s beautiful weather and vibrant lifestyle, it’s no surprise that more homeowners are investing in home extensions to refresh and expand their living spaces. Whether you’re looking to modernise your home, create more room for your family, or adapt to evolving lifestyle needs, extending your home has become a smart, stylish way to achieve those goals. Brisbane’s sunny climate and love for outdoor living are key drivers behind many of the trends we’re seeing. Let’s take a look at the top home extension trends for 2025 and see how they’re transforming homes across Brisbane.
Maximising Natural Light

With Brisbane’s reputation for almost year-round sunshine, it’s no surprise that homeowners are focusing on bringing as much natural light into their homes as possible. Maximising natural light isn’t just about the aesthetics, but it’s also a practical and eco-friendly choice.
Popular strategies include adding skylights, large windows, and even glass walls to flood homes with sunlight. Open floor plans are another favourite, allowing light to travel freely through the space. By reducing the need for artificial lighting, homeowners can cut energy costs while enjoying brighter, more inviting living spaces. Also, the benefits of this go beyond energy savings. More natural light has been shown to boost mood, productivity, and overall well-being.
Eco-Friendly Designs

Sustainability is here to stay and Brisbane homeowners are leading the way with eco-friendly extensions. Eco-conscious materials like recycled timber, bamboo, and sustainable concrete are in high demand, helping to reduce the environmental impact of construction.
Energy-efficient designs are also key with solar panels, energy-saving appliances, and rainwater harvesting systems being seamlessly integrated into homes. Water-smart homes are particularly important in Brisbane, where conserving water can significantly reduce household costs. Brisbane’s warm climate makes effective insulation and natural ventilation essential for keeping homes cool during the summer without relying too much on air conditioning. While eco-friendly designs may initially seem like a bigger investment, understanding the costs of house extensions in Brisbane will show that these choices can offer long-term savings on energy bills, making them a worthwhile consideration. By making these eco-friendly choices, homeowners can not only reduce their carbon footprint but also future-proof their homes against rising energy costs.
Outdoor Living Spaces

Brisbane locals love spending time outdoors and home extensions are all about making the most of the city’s great weather. A growing trend is to create a seamless transition between indoor and outdoor spaces with homeowners adding covered patios, decks, and outdoor kitchens to expand their living areas. These outdoor spaces are perfect for relaxing, entertaining, or just enjoying the beautiful climate. Folding or sliding glass doors are a popular feature, allowing easy access to the outdoors and helping to blend the two areas. Durable, weather-resistant materials like composite decking, natural stone, and exposed aggregate concrete patios are being used to ensure these spaces last through the seasons.
Blend Old and New
Brisbane is famous for its charming heritage homes, especially the iconic Queenslanders and homeowners are increasingly looking to balance preserving this charm with modern conveniences. This trend of blending old and new is giving homes a unique, personalised feel. Many extensions are designed to keep traditional elements like timberwork, gabled roofs, or verandahs while introducing contemporary features like modern kitchens, open-plan living, and sleek bathrooms.
Multigenerational Living

With the rising costs of housing and changing family dynamics, multigenerational living is becoming more common. Home extensions are increasingly designed to cater to families with ageing parents or adult children living under the same roof. These extensions often include self-contained living areas with their own entrances, bedrooms, and bathrooms, providing both privacy and independence. Future-proofing these areas is also important such as incorporating wider doorways, accessible bathrooms, and ground-floor bedrooms to accommodate mobility needs as family members age.
If you’re considering multigenerational living, you may also be weighing up whether to extend your house or move. Both options come with their own set of advantages and challenges, but extending your home could be a more practical solution for keeping your family together while adding value to your property.
Home Office Spaces

The shift to remote work has become a permanent change for many people, which means home offices are now an essential part of home extensions. Having a dedicated space for work that’s comfortable and functional is more important than ever. Soundproofing, ergonomic designs, and plenty of natural light are top priorities for creating productive workspaces. And with the demand for flexibility, many homeowners are designing multi-purpose rooms that can double as guest rooms or creative studios when needed.
Smart Home Technology Integration
Technology continues to evolve and smart home systems are becoming a must-have in modern extensions. From energy-efficient lighting systems to smart thermostats and home security, Brisbane homeowners are embracing tech-savvy solutions for greater comfort and convenience. Automation is a major focus with features like motorised blinds, smart speakers, and climate control systems being controlled remotely via smartphone apps. These innovations make daily tasks easier and help homeowners reduce energy consumption while staying in control of their home’s environment.
Conclusion
If you are a homeowner looking to extend their homes in 2025, these trends reflect a strong focus on maximising natural light, embracing eco-friendly designs, and creating flexible spaces that suit modern living.
