Hear from our clients



How much will my Box Hill renovation cost?

The cost of a renovation or extension varies depending on the size, complexity, and style of works. A ground level open plan renovation typically costs more than a second storey extension just because of the works involved. 

A home extension is often more affordable than you might think, depending on what you are looking to undertake. From the initial consultation through to the final touches, we are committed to keeping your costs low. Speak to our team and book your Free Design Consultation today.

How do I know if my home is heritage listed?

Melbourne has a wonderful array of heritage architecture which it is the responsibility of homeowners to preserve. But having period features does not preclude you from investing in a stylish and tasteful renovation. Supa Group can help you to navigate planning obligations and ensure the finished outcome is special and sustainable.

If you have period features on your home, why not visit the Heritage Council of Victoria website and identify any potential obligations of being a heritage homeowner.

Do I need to move out of my home while renovations are taking place?

Many of our clients opt to remain in their homes while renovations are taking place. So long as you have an operating bathroom and a toilet, your home is habitable. Of course, there are some disruptions which will take place such as noise, dust, and debris — but we will work with you to make sure disruptions are as minimal as possible.

What kind of building permits or planning permissions do I need for my home in Box Hill?

There is a range of permits and planning hoops that you will need to jump through,  but we can help you navigate every aspect. When you work with us, we can ensure that your renovation or extension is completed on budget and on time. 

It may seem daunting to consider undertaking a renovation, but with us on your side, we make the process simple and ensure your project meets all council requirements.
