Extend the home you already love

Moving house is expensive and disruptive. Often the smarter choice is to add the space you need to the home and neighbourhood you already love. An extension can transform how your home works without starting from scratch.

We design extensions that feel like a natural part of your home, matching materials, proportions and style so the new work sits comfortably alongside the old. The result is more room, better flow and real added value.

 Trustindex verifies that the original source of the review is Google. Avenue Building Group have been nothing short of exceptional in delivering my bathroom renovation. Anthony initially turned up on time to quote, got the quote back to me within 24 hours, and was able to start the following Monday. While this wasn't a huge job, there were some tricky aspects to it such as under floor heating that we wanted to try to salvage. Anthony and his tradies took great care in their work and really pushed to meet deadlines. These works were part of a house sale due to separation and I have to say that not only is Anthony an outstanding builder who knows his stuff and employs highly skilled tradies, he's also a very kind guy who understood the impact that something like this can have on people. I cannot recommend Avenue Building Group highly enough and will be using them for any future renovations or builds that I undertake. It's rare to find a builder you can trust and who isn't just out to hit you with variations but I can assure you Anthony is one of those rare builders that you can absolutely trust to be fair and reasonable, all while delivering high quality works and finishes.

 Trustindex verifies that the original source of the review is Google. Avenue Building Group have been amazing from the get go. I organised a complete home renovation with their team. From planning to carrying out the job to care at the job site…I felt one hundred percent heard throughout. Amazing quality with detail and workmanship. It was a pleasure working with Anthony and his team. Looking forward to my next project with them. The team definitely deliver way above expectations and took the stress out of home improvement.

Home extension FAQs

Have a question we have not covered? Call us on 0411 708 256 and we will happily talk it through.

Do I need council approval for a home extension?

Most extensions require some form of approval, and the exact requirements depend on the size of the work and your local council. We handle the approvals and permits for you as part of the project, so you do not have to navigate it alone.

How long does a home extension take?

It depends on the size and complexity of the extension, but we give you a realistic timeline with your quote and keep you updated throughout. (Typical timeframe to be added.)

Can you match the extension to my existing home?

Yes, and it is one of the things we care about most. We match materials, proportions and detailing so your extension looks like it has always been part of the house, not an afterthought.

Can I stay in my home during the build?

In many cases, yes. We plan the works to keep disruption to a minimum, and we will talk you through what to expect for your specific project so there are no surprises.

Do you offer fixed-price contracts?

We do. You receive a clear, fixed-price contract before any work begins, so you know exactly what your extension will cost from the outset.
