Frequently asked questions

Do I need a permit for Thornbury home extensions?

Yes. You will need to obtain a permit issued by the registered building surveyor for significant home extension projects. This is the last step in the process before construction begins. In some cases, such as if you’re adding flood overlays or strata tiles to your home, you will also need council approval. This is called planning permission.

Can I live in my home during the extension project?

Usually, our clients can stay in their homes while we complete your home renovations or extension project. However, we cannot give you safe access to areas of the home, such as the kitchen or bathroom, you will need to find temporary accommodation elsewhere.

Will Supa Group use the contractors that I want?

Let us know if you know building contractors that you want us to work with, let us know. We’re happy to collaborate with builders across Melbourne. We will ensure they meet our safety standards, provide the necessary insurance and OH&S credentials, and meet the deadlines provided for your project.

Can I add home extensions to a Thornbury heritage-listed property?

Yes. We can add home extensions to a heritage-listed property. However, it may take more planning and council permissions to go ahead. At Supa Group, we will work closely with the Darebin city council to get all permits approved. 

We aim to preserve the property’s structural integrity while transforming the space with seamless ground floor or two-storey extensions.
