Understanding the needs of your family

Many types of house extensions are available for families looking to increase their living space. Before starting a home extension project, read up on some ways you can transform your existing house.

Why build an extension?

There are many reasons why you might choose a particular type of extension. Here’s why you should consider home extensions in general.

Remain in the home you love

If you love the area where you live, you shouldn’t have to leave to accommodate your growing family.

Increase the liveability

Different home extensions can add extra living space and invite natural light into your home.

Add value to your existing home

Different types of extensions can potentially double your home's value when it comes time to sell.

Planning permission for types of extensions

Depending on what you want to achieve with your new home extensions, it’s likely that you’ll need local council approval. Any renovation project needs to go through the requisite steps to ensure that it meets local bylaws.

Supa Group can manage the planning permission process on your behalf. We will work with you to develop a solution that meets your needs and those of the local government. Learn more about our process on our dedicated page.
