Our building services

As reliable house extension builders in Melbourne, we deliver experience and quality in every job. Rest assured that when you engage our building services, you can rely on them. We go the distance, providing value and peace of mind at every stage. We’ll manage the paperwork, deal with your council and provide honest progress updates whenever you like.
We have worked with families across Melbourne to produce home renovation solutions that add space and style to beloved homes. Our renovation services will add years of liveability and value to your home, whether by building new bedrooms, extending entertaining spaces or putting in a spacious home office.

Discover how we do it

Homes are meant to be lived in. We keep this at the core of our projects — it's what makes us one of Melbourne’s best home extension builders.

As Melbourne’s extension specialists, it’s our job to turn your house into a home. We start every job by focusing on the foundation — you. Tell us about yourself. Tell us about your family, hobbies and interests. Tell us what you need, but most importantly, tell us what you’ve always wanted.

You can’t always build your dream home from scratch. Maybe you’re already in love with what you have — the memories within your four walls and the community outside of them. The problem is those walls just aren’t quite big enough anymore.

Every decision we make puts your well-being first. Go ahead and add an en suite and a walk-in wardrobe to the master bedroom for a little personal space. Extend the kids’ bedroom so they have plenty of room to play with their new sibling. Rearrange the ground floor to capture that golden afternoon sunlight. Our designs answer one question: how do you want to live?

The Supa Group difference

Home extensions and renovations

Supa Group is one of the most experienced home extension and renovation companies in Melbourne. Established in 1974, we are one of Melbourne's earliest home renovation companies. Initially offering small-scale home renovations and extensions, we now specialise in second-storey and ground-floor extensions across the greater Melbourne area. 

With such a rich and expansive history behind us, we have become experts in large-scale projects such as kitchen remodelling, bathroom and bedroom renovations, and open floor plans for more living space.

Undertaking a DIY home renovation can be a headache-inducing process, especially if progress is not going to plan. Work can often halt and budgets get blown out, which is why it’s best to call on the services of a professional home renovation builder who will provide a cost-effective, time-conscious solution that will allow you to create your dream home!

Trade coverage

One of our great strengths is our extensive trade coverage and network of suppliers, which we have developed over many years. We have long-term relationships with material suppliers to ensure that your project can be completed within the timeframe and budget.

Whatever style of home you may have - Victorian, Edwardian, Federation, Art Deco, Californian Bungalow, Post-War Austerity, Mid Century Modern, and beyond, Supa Group have the designers and experience to make sure you get a quality job in a reasonable timeframe. We know how to find, coordinate and supervise the best tradespeople in the business to build your dream home.

Award-winning service

Supa Group is a long-term member of the Master Builder and Housing Industry Association (HIA). They’ve honoured us with a number of awards over the decades, of which we are so proud. Our enviable reputation as a highly trusted house extension company in Melbourne is based on our ability to deliver excellent outcomes for our clients. We take the time to understand your needs and work with you to create a tailored project plan.

We offer full in-house services as both a design and build company. This means that when you work with us, you work with tradespeople who we trust to deliver the absolute best in service.

Fixed price and completion times

To ensure you get peace of mind, we give you full clarity at the very beginning of your project. You'll know exactly how much you have to pay and how long your home extension project will take. We also carefully pre-plan before your project begins to head off any nasty surprises along the way!

During the consultation process, we undertake an order engagement and then a site measure. Here, we visit your home, engage a plumber, and look at your home’s foundation to identify any issues that might cause a material variation. Before the contract is offered, we sit down with you and decide whether or not we can proceed within budget.

Variation Orders are possible after the project commences if there are aspects of the project that clients want changed. This mechanism is available under our HIA contracts.

Successful projects all across Melbourne

We have built extraordinary first and second-storey extensions across Melbourne. Over the past 45 years, we have completed thousands of house extensions in areas including Coburg, Northcote, Yarraville, Alphington, Fairfield, Kew, Burwood, Camberwell, Glen Iris, Glen Waverley and Bentleigh, amongst others. With our sterling reputation, we can liaise with your council to quickly secure your building permit and get the right to work. See if we’ve built in your area on our locations map.

If you’re planning on creating more space with a second-storey extension or want to increase your property value, book a free design consultation today to see for yourself why Supa Group is one of the best in the industry.
