Our Altona Homes

We’ve also completed renovations and extensions in the pocket of Altona affectionately known by locals as the Birdcage. From Robin Street to Emu Avenue, we know Altona homes inside out.

What our customers are saying

Andrew and Mark of Yarraville

Despite all the stories you hear about how difficult building can be it was a fairly painless process thanks to the professionalism of the Supa Group team and the quality of their people. We even lived in the house throughout the process.

Ian and Lisa of Caulfield South

Thank you so much for the spectacular job you have done. We are very happy with the outcome and it was an absolute pleasure working with all of you. We appreciate the expertise, honesty and care we received throughout the renovation.

Melissa of Coburg

Very happy with our recent renovation with Supa Group. Just like another reviewer, we wasted time and money trying to go through an architect. Supa Group’s design was far superior and more cost effective.

About Supa Group

Just like our home extensions and renovations, Supa Group has stood the test of time. We were founded in 1974 by Frank Way, laying a solid groundwork of commitment and service to his staff, subcontractors, and most importantly, his clients — families seeking to remain in the home they know and love.

Now owned and operated by Neil Gardiner, Supa Group’s original commitment has remained the same. Today, our clients are still offered the peace of mind that comes with hiring a builder who takes projects from conception to completion.

Our reputation as a multi-award-winning master builder is built upon a foundation of commitment to quality. We are proud to deliver best possible outcomes for our clients, and we want to do the same for you. Contact us for a free design consultation, and begin building towards the future.

Can I help with the design?

A key part of our process is incorporating your style, design ideas, and wishes for your home extension. Your input is critical to ensuring we create a stunning extension that you love. Because we custom-design every extension for our clients, your input will be warmly welcomed to give our designers the direction they need to create your dream home.

Can I get my own tradespeople to work on the home extension?

A number of our clients choose to use their own plumber, or electrician for example. We are happy to work alongside your own tradespeople so long as they meet all the relevant Occupational Health and Safety requirements and complete their insurance requirements.

How long with it take to build my Altona home extension?

The answer to this question depends on the build you are putting in place. With every Supa Group home, there are three distinct phases – the design phase, the contract preparation phase, and the build phase. Once we have completed the design phase, we can give you a solid estimate of how long your build will take. It is best to contact us if you do have a specific timeframe in mind and we can discuss this with you.

What if I change my mind about something halfway through?

We understand that sometimes things might not look exactly as you might have planned with your home extension. If you do change your mind once our builders have already started works, you are welcome to make changes. Please note, however, changes may incur additional costs.
