Fitting your family members under one roof

As Melbourne's population diversifies and housing options change, home extensions are the perfect way to support your family. Whether extending your ground floor for your elderly family members or adding a separate living space for your adult children, house extensions are designed to foster closer family connections while maintaining individual privacy.

We all like to watch our own television shows, be able to regulate the volume to our own hearing abilities and not have to queue in the morning for the bathroom so with a bit of thought this can be factored into a design to arrive at the ideal outcome for your situation.

With a focus on functionality, aesthetics, and seamless integration into the existing structure, multigenerational house extensions offer a tailor-made solution for modern families looking to live harmoniously under the same roof.

Making space for the parents through a multi-generational living plan

This family loved their Coburg home and eagerly anticipated the annual visit of parents from the UK, the home lacked the space for them all to live comfortably under one roof for lengthy periods of time. So the client came to Supa Group looking for a Multi-generational living plan.

Existing floor plan

Proposed floor plan

The outcome

In this case the brief was to extend the house, create separate sleeping and living quarters for the grandparents, whilst still providing a floorplan that was conducive to a comfortable lifestyle without fear of losing privacy.

The old undercover entertaining area made way for the ‘Grandparents Wing’ which comprised of a private living area, wet bar with a meals area and access to the spacious bedroom with bespoke BIR and luxe ensuite.

The extensions distinctive design was not only creative but smart with both the living area and the ‘grandparents wing’ having independent access via double glazed stacking doors to the charming rear garden. The design also afforded views of the deep garden through the pergola.

Extending is an easier option for your family


Extending your existing home is often more cost-effective than demolishing and building anew, as it utilises your current structure and foundation, saving on construction and demolition expenses.

Preservation of Character

Extending allows you to retain the architectural character and charm of your current home, which can be important for families who value their property's sentimental and historical aspects.

Time Savings

Extending typically requires less time than constructing an entirely new home, enabling you to accommodate multi-generational living arrangements more quickly.

Minimal Disruption

Home extensions can be completed with less disruption to your family's daily life compared to the extensive construction process required for a new build, making it a more convenient option for multi-generational households.

Can I add an extension to my home?

One thing that Supa Group is really good at is customization, and understanding what’s possible for your individual situation given site and financial constraints.

Constraints include:

  • Any overlays on the property such as a heritage or other planning overlay
    Site set back requirements (front, rear and side) to comply with ResCode
  • The size of your block
  • How your home is currently situated on the block
  • The condition of the existing home
  • Your budget and understanding what is a reasonable amount to spend on your property

Supa Group’s Design Consultants are highly experienced in understanding site constraints and have the expertise in providing the best customised extension solution for people’s homes.
