Building a House Extension

Request a Call Back

Is your family outgrowing the space in your home? Perhaps you want to add a big home office or a rooftop pool you’ve always dreamt of. Whether it’s adding new bedrooms, recreational areas or general living space, home extensions allow you to stay in the house you love and add value and liveability for years to come.

Why Build a House Extension?

House extensions offer a range of advantages for homeowners such as:

  • Additional space for a bigger kitchen
  • More or bigger bathrooms and bedrooms
  • The ability to convert your home to an open-plan layout
  • Increase storage space
  • Allow more natural light and better ventilation
  • A second-storey extension for more living space or a rooftop recreational area

Greater square meterage automatically increases the kerb appeal and market value of your property


What Are the Different Types of House Extensions?


Ground Floor Extensions

Single-storey extensions can be a cost-effective way to add space, refresh and modernize your home, and enhance the existing layout. There are a number of reasons to go for a ground floor extension.

From catering to the needs of a growing family, to reflecting a change in lifestyle, to upgrading your living environment with a more modern and eco-friendly open-plan layout, single-storey extensions add great value and functionality if you wish to remain in your current home for the foreseeable future.

To ensure that your completed ground floor extension meets your expectations and needs, make sure to work with a professional and experienced home renovation specialist.

Second Storey Extensions

If you wish to keep your ground floor layout as it is but need additional space, it’s time to build up!

Adding a second storey to a house allows you to transform your home with a whole new level of living space, giving your family room to grow especially if you have teenage kids in need of privacy as they enter early adulthood.

Depending on the architecture and condition of your home, building up (adding an extra floor) can be quicker and more cost-effective than building out (extending the same floor) due to excavation and foundation work required for ground floor extensions.


Triple Storey Extensions

Ever dreamt of having your own rooftop deck for BBQ parties with a stunning view of the Melbourne city skyline? What about a rooftop swimming pool for an elevated swimming experience?

Having a third floor not only adds a wow factor to your property in aesthetics and value but also creates endless opportunities for added functionality, such as:

  • Additional play areas for the kids
  • More breathing space for the family to spread out
  • A dedicated upper floor for entertaining with a beautiful view

House Extension Cost

Ground floor extensions can cost between $2000 to $4000 per m2, while second storey extensions can range from $3000 to $3500 per m2.

The following factors will affect the cost of your home extension:

  • The size of your property
  • The type of extension: same level or additional floors
  • Quality of building materials
  • New appliances and fittings
  • Permit requirements
  • External consultants such as a land surveyor, engineer, etc
  • Excavation or demolition work
