Live in the space you’ve always wanted

At Supa Group, our team creates unique and stunning ground floor home extensions. A ground floor extension from Supa Group is the ideal way to maximise the space and functionality of your home.

As ground floor extension specialists, we believe in turning the house you love into a home. We add space and style to your home to give it the liveability you need to grow into the future.

When adding to the ground floor, we create unique, functional designs that you just can't get from a knockdown rebuild. Our in-house designers are here to give you even more value for money by creating a functional design that works within your budget, without the need for additional architecture services.

Extending your ground floor will add much more space, increase the square meterage, and add significant value to your home. From new living and dining areas, to a brand new quiet bedroom retreat, to an expansive entertaining area, there's nothing we can't do.

Your questions answered

Will I need to move out during construction?

Generally speaking, you’ll be able to stay in your home throughout the project as long as you have access to a bathroom and kitchen. You’ll be able to discuss all your options with the Supa Group team.

How much do ground floor extensions cost?

The cost of a ground floor extension varies depending on the scope of works. Ground floor extensions typically involve new kitchens, pantries, laundries, and open plan living areas. But they may also be as simple as adding a couple of bedrooms or a living room. Other factors include the overall size and type of materials used.

Every project is different, so the best way to find out how much your ground floor extension will cost will be to book an initial consultation with one of our experienced Design Consultants.

Can you renovate my existing house as well?

Yes, we can renovate existing bathrooms, kitchens, bedrooms, and other areas as part of your extension project. Learn more about renovating with your extension.

What type of ground floor extension can I have?

When it comes to completing a ground floor extension in your existing home, there’s no limit to what can be achieved. It’s your property and your renovation project.

We can deliver quality home extensions that can add the following to create more modern homes:

  • More space
  • New space
  • Family room
  • Laundry room
  • Extra bedroom
  • Guest bedroom
  • Home theatre
  • Air conditioning
  • Living area
  • Alfresco dining area
  • Outdoor space

The perfect solution may be a bigger house, or an extended single storey home. Contact us today, and let's work together to achieve your home improvement dreams.

Do I need planning permission for my ground floor extension?

Depending on where you live, your local council may require you to seek planning permission or a building permit before you begin. Council approval is an essential part of our planning process, so we’ll let you know what is required in terms of other costs, like stamp duty.
