As property prices climb and family dynamics shift, more Australians are embracing multigenerational living. It’s a practical response to housing affordability, ageing populations, and the desire for stronger family connections. One solution gaining momentum is the backyard granny flat.

Granny flats, also known as secondary dwellings, are self-contained living units built on the same block as a primary residence. Whether it’s to house ageing parents, give adult children independence, or accommodate extended family, these dwellings offer flexibility without the need for major renovations or relocation. They allow different generations to stay connected, while each still enjoys a sense of privacy and autonomy.

Why Multigenerational Living is on the Rise

Several social and economic factors are contributing to the rise in multigenerational households:

• Housing affordability: Rising property and rental prices make it harder for younger people to move out or for older relatives to downsize independently. Granny flats offer a more accessible housing option.
• Aged care alternatives: Living close to family provides emotional support and often avoids the high costs and emotional toll of residential aged care facilities.
• Cultural norms: In many cultures, it is common for multiple generations to live together under one roof or on the same property.
• Childcare and support: Grandparents living nearby can offer hands-on help with young children, school pick-ups, and day-to-day parenting support.

This resurgence in multigenerational living reflects broader lifestyle changes, prioritising connection, care, and cost-efficiency.

What Makes a Granny Flat Suitable for Family Living?

To support multigenerational living effectively, a granny flat must balance comfort, privacy, and accessibility. It should feel like a home in its own right, not just an add-on to the main residence. Key features to look for include:

• Separate entrance: Allows independence and reduces daily disruptions between households.
• Full kitchen and bathroom: Ensures the dwelling is truly self-contained, giving residents the ability to live independently.
• Single-level design: Particularly important for elderly occupants who may have mobility concerns.
• Soundproofing: Enhances privacy for both dwellings and reduces noise between homes.
• Outdoor space: A small garden or patio can greatly improve quality of life and give residents a private retreat.

A well-designed granny flat doesn’t just add square metres – it improves how a household functions together.

Benefits for the Whole Household

The advantages of building a granny flat extend across all age groups. Here’s how different generations benefit:

• Older adults: Gain security and family connection while retaining independence and dignity. It’s often a better alternative to aged care.
• Adult children: Can save money on rent and build savings for a home deposit while still living in a semi-independent space.
• Parents: Benefit from extra support in child-rearing and reduced long-distance care responsibilities.
• Children: Grow up surrounded by grandparents or extended family, creating closer bonds and shared memories.

Multigenerational living offers both practical and emotional rewards – from shared chores and expenses to everyday companionship.

Things to Consider Before Building

Before planning a granny flat, homeowners should take several practical steps to ensure the project goes smoothly:

1. Check local regulations: Each local council has its own rules around floor area, setbacks, and occupancy. These must be reviewed before design and construction begin.
2. Assess the site: Consider access for construction vehicles, utility connections, and how the structure will affect yard space and privacy.
3. Think long-term: Plan for how the granny flat might be used over the next 10-15 years. Flexibility is key.
4. Budget realistically: Factor in all costs, including design, planning approvals, excavation or slab work, and finishes.
5. Plan for accessibility: Features like wide doorways, level thresholds, and grab rails may not be needed now, but they future-proof the home.

Taking the time to plan properly ensures that the granny flat meets current and future family needs.

Design Ideas That Work

Modern granny flats don’t have to feel basic or cramped. Thoughtful design choices can make a huge difference:

• Use high ceilings and large windows to create a sense of space
• Choose neutral colours and quality finishes for longevity
• Incorporate built-in storage to maximise internal space
• Provide adequate lighting both inside and out for safety and comfort

Where possible, involving the future occupant in the design phase helps ensure the final space is practical and enjoyable.

A Realistic Alternative to Moving

For many families, the decision to build a granny flat comes down to keeping loved ones close while avoiding the upheaval of moving or the financial strain of aged care. It allows parents and children to maintain routines while being close enough to support each other daily.

Companies like DuaLiving, which operate in South East Queensland and Northern New South Wales, specialise in creating quality granny flats and other backyard dwellings. They assist homeowners with layout choices and help navigate local planning approvals, making the process less stressful.

Final Thought

Multigenerational living is nothing new – but it’s finding renewed relevance in today’s housing and social climate. A granny flat is more than an extra building; it’s a bridge between generations, offering support, independence, and shared time together.

With the right planning and design, it becomes an investment in both property and family life – one that can adapt to changing needs while keeping everyone connected and cared for.
