Your questions answered

Will I need to move out during construction?

In most cases, homeowners find it preferable to move out of the home for at least part of the construction. As an experienced second-storey extension builder, we will plan to minimise disruptions to your living area. You can continue to live at home throughout the construction as long as you still have access to kitchen and bathroom facilities. 

You can discuss all options with our team, and your building supervisor will also keep you up to date as each stage of your construction progresses, so you’ll know exactly what to expect every step of the way.

How much do ground-floor extensions cost?

The cost of a ground-floor extension varies depending on the scope of the work. 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 single-storey 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. We also offer second-storey extension services. 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 statutory costs, like stamp duty.
