Our home extension services

At Supa Group, we know how much you love living in Balwyn.
We offer full service home extensions and renovations in your area, allowing you to add space and style to your home without moving away. We apply a 3-step process to guide you through The Design Phase, The Contract Preparation Phase, and The Build Phase. You’ll be in touch with every step of the process until you are ready to move back into your dream home.


Our Balwyn Homes

At Supa Group, we know what makes Balwyn special. From the area’s enviable collection of prestigious schools, to Balwyn Cinema on Whitehorse Road, there’s plenty for families to fall in love with. We know because we have renovated Balwyn homes from Burke Road to Union Road, and everywhere in between.

Our experience in the area has given us an intimate understanding of the inner workings of the City of Boroondara council. Not only can we help you navigate the planning and permit requirements of the council — we can ensure that your new Balwyn home extension protects heritage overlays.

We believe that families should stay in the areas they have grown to love. We’re here to bring your Balwyn renovation project from inception to completion, giving you plenty of space and style to enjoy in the years to come.

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 make design input into my new Balwyn home extension?

Your house wouldn’t feel like much of a home if it didn’t possess some of your personal style. By engaging Supa Group, you’ll begin to work with a team of designers to craft the perfect lifestyle renovation. Whether it’s art deco, traditional, federation, or contemporary, the Supa Group team know how to bring your style out.

What if I have my own tradies in mind?

We believe the best outcomes are delivered from a cohesive effort. If you have a preferred tradesperson you’d like to see on the tools, we would be happy to accommodate them, as long as they comply with our insurance prerequisites and Occupational Health and Safety standards.

The Supa Group team works to concrete completion dates. Your tradesperson will have to work to our deadlines to ensure that our agreed-upon deadline can be met.

How do I know if my Balwyn home has a heritage overlay?

Balwyn saw its first homes built pre-Federation in the 1850s. Today, the area still retains plenty of iconic elements of Australia’s colonial past. Some of these homes and buildings are of historical significance, and have been preserved by heritage overlays.

If you are concerned that your home falls under a heritage overlay, get in touch with Supa Group. We can investigate the history of your home and advise you of the changes we can and cannot make when completing your Balwyn home extension or house renovation.

Can I keep living in my Balwyn home during the extension or house renovation?

That depends on your personal preference. The Supa Group Build team can usually accommodate your request to remain living at home, provided that certain amenities remain intact. If your bathroom or kitchen is out of action for an extended period of time, you may have to live elsewhere for the duration of the project.
