Outstanding building services

It’s time to take your home up a level. Double storey extensions can add immeasurable worth to your home and lifestyle.

As upstairs extension specialists, we believe in turning the house you love into a home with all the space you need for your family, lifestyle, and comfort.

When building a second storey, we create unique designs that you can’t get from a knockdown rebuild. With our in-house designs, we provide outstanding value for money since you don’t need additional architecture services. And we do it all within your budget.

Adding on top of your existing ground floor with a two storey extension will add more space, an increase in square metre area, and an increase in significant value to your home. From comfortable bedrooms for every child, to a luxurious parents' retreat, to a vast open-plan living space and entertaining area, the options are limitless.

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. We plan a double storey extension to minimise disruptions to your living area, and you can continue to live there 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 second storey extensions cost?

This entirely depends on the details of your project. But you can rest assured that the Supa Group team will work within your budget. Since we handle all the design and construction ourselves, we can ensure that your extension stays on schedule and on budget.

The exact cost of your project will depend on a number of factors, which may include:

  • External vs internal renovations
  • Adding an additional storey
  • Poor access
  • Large or small block
  • How to best achieve minimal disruption
  • Other changes to the existing home or existing dwelling

To understand the house extension costs of what you want to achieve with an upper storey addition, get in touch with our design consultants.

Are second storey extensions more difficult than ground floor extensions?

At Supa Group, we are specialists in creating the perfect double storey extension for clients. Since we have all the necessary expertise, a second storey extension isn’t actually any more difficult for us than a ground floor extension. Depending on the specific details of your home and block, it may actually be easier and less disruptive to extend up instead of out.

What can be achieved with a second storey extension?

Build upward and extending outwards can add major advantages to a home, including new space and style to the existing structure. A common second storey extension involves adding a master bedroom or two bedrooms for children plus a living area. As part of an entire process of ground and second story extension, we can:

  • Retain garden spaces for children
  • Add extra bedrooms
  • Improve storage space
  • Increase living space
  • Invite more natural light
  • Create new outdoor living space
  • Work to budget and time constraints
  • Separate bedrooms from main living areas

For a growing family, no home renovation is too much trouble. From a simple ground floor extension to building a second storey, Supa Group can do it all.

Are there any council regulations I should be aware of before adding another storey extension?

Yes, local council requirements are an important part of the home extension process. When adding a second storey extension, it’s especially important to understand what you can and cannot do in terms of changing the facade and structure of a building, particularly if it has a heritage overlay.

Before the construction process takes place, our experienced design consultants will advise you of what’s required in terms of local council approval and town planning. Get in touch with a project manager or design consultant for a free consultation.
