Hear from our clients



If my home in Mitcham is heritage-listed, can I add extensions?

Absolutely, although we will need to attain permits to carefully design and create the renovations for your home. Supa Group understands that many councils are hesitant to allow new construction on heritage-listed properties. 

We have the building experience and expert advice needed to acquire the necessary building permission, with decades in this industry and a commitment to quality builds. We are well-placed to assure Whitehorse City Council that our renovations will preserve the character and beauty of your heritage-listed property.

Can Supa Group collaborate with the tradespeople I choose?

Absolutely. Our friendly team are happy to work with any tradespeople you choose for your Mitcham extension. We require that your preferred tradespeople have the necessary experience and qualifications to complete the work to our high standards. We provide you with a list of credentials, insurance coverage and OH&S requirements that they must meet. And since we offer fixed completion dates for your project, they will also need to work to our schedule.

Can we stay in our Mitcham home while renovations are done?

We can work on your renovation while you continue to live in your house, as long as you have access to your bathrooms and kitchen. If not, we will do our best to complete our work as soon as possible so you can return home.

How much do home extensions in Mitcham cost?

Each renovation comes with a unique quote reflecting the complexity of the necessary work, the materials required and the labour involved to bring it to life. 

A bathroom renovation or extension to your kitchen will, of course, cost substantially less than a large scale home renovation. Until you’ve settled on a design and timeframe, we can’t advise you of an exact price — but rest assured, once a figure has been set, it will not change. We are the extension builders Mitcham residents go to when they want a fixed fee with no hidden costs.
