Read testimonials from homeowners who trusted Supa Group for home extensions and renovations in Melbourne. See how we improved space, comfort and liveability with quality workmanship.
“The whole process was very relaxed and easy from start to finish. We loved where we live and didn’t want to move, so the goal was to turn our house into a forever home that worked better for our family. That meant adding an extra bathroom, creating bigger rooms for the kids, and opening up the living space at the back. The team really helped bring that vision to life and even suggested ideas we hadn’t thought of. They were great to deal with, very organised, easy to communicate with, and always kept us in the loop. The workmanship is perfect, we genuinely couldn’t fault anything, and the end result turned out even better than we expected.”

“We bought the house knowing it was still in its original 1950s condition, so the goal was to modernise it while still keeping its character. We wanted a better layout, a second bathroom, and a more open living space that worked for everyday living. The team really understood what we were trying to achieve and helped bring it all together in a practical, efficient way. They were easy to deal with, kept things moving, and communication was clear throughout the entire build. The workmanship is excellent, and we were really impressed with both the quality and how quickly everything was completed.”

Find answers to common questions about key aspects of the house extension and renovation process in Melbourne.
Many home extensions in Melbourne require council approval, depending on zoning, overlays and your design. You may need a planning permit, a building permit, or both. A good first step is to check your property on VicPlan, then confirm the requirements with your local council and the VBA. This helps reduce delays later.
Cost depends on the size and complexity of the extension project, your finishes, and the scope of the work. A second storey upgrade usually differs from a ground floor addition. Renovation and extension projects also vary based on what stays and what changes in your existing home. For clear pricing, request a design consultation and get a free quote from Supa Group.
Yes, many homeowners choose to do both to improve layout and functionality in one build. It can be a practical solution if you want to upgrade key areas while extending your home. A well-designed extension should blend seamlessly with your existing home. It can add space, improve comfort, and support long-term property value. Your builder can also advise on extension options that perfectly suit your block and budget.
It depends on the scope of the project and which areas are affected. Some home renovations in Melbourne allow you to stay, while others require temporary accommodation. If you’re doing a kitchen or bathroom renovation, moving out can reduce disruption and help the work progress safely. Your project manager will confirm the best approach during planning.
