What our clients say

Hear from Melbourne homeowners who’ve trusted our experienced team. These testimonials reflect customer satisfaction, clear communication, and results built to last.

“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.”

“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.”

Frequently asked questions

We answer the most common questions about renovating or extending a home with Supa Group.

Do you manage the entire renovation or extension process?

Yes. Supa Group manages every stage from initial design through to construction and handover. Our integrated team oversees planning, approvals, building and site management, so your project runs smoothly without the handover gaps common with multi-party builds.

What types of renovation projects do you specialise in?

We specialise in large-scale home renovations and extensions, including single and double-storey projects. Our focus is on substantial home transformations rather than minor cosmetic upgrades, allowing us to deliver better outcomes through proven systems and experienced teams.

Who will I be dealing with throughout my project?

You’ll work with a dedicated Supa Group team from start to finish, including designer consultants and experienced builders. This ensures clear communication, accountability and consistent decision-making at every stage.

Do you handle council approvals and permits?

Yes. All council approvals, permits and compliance documentation are handled in-house. Managing this process internally helps reduce delays and ensures your renovation meets all regulatory requirements before construction begins.

How do you provide cost and timeline certainty?

Before construction starts, we confirm:

  • Fixed pricing.
  • A guaranteed start date.
  • A clear construction timeline.

This approach allows you to plan with confidence and avoids unexpected costs or scheduling changes mid-build.

Can you customise the design to suit my home and lifestyle?

Absolutely. Each design is tailored to your home’s structure, site conditions and planning requirements. We balance aesthetics with functionality to ensure your renovation supports your lifestyle now and into the future.
