Melbourne’s Changing Demographics: How Granny Flats Address Family Needs

If it isn’t already evident, populations around the world are ageing, and Australia is no exception. Over the past decade, granny flats in Melbourne have grown in popularity, driven in part by the rising cost of living, which has made it increasingly difficult for adult children to afford a place of their own.

As a result, granny flats offer a practical solution, allowing families to support independence while staying connected on the same property. This combination of social and economic factors has driven sustained demand for this style of living.

With over 30 years of experience and more than 10,000 homes built, Todd Devine Homes has seen this shift firsthand, helping families create functional, private spaces that adapt to changing household needs.

The Demographic Shifts Putting Pressure on Melbourne Families

For Melbourne homeowners, granny flats are rising in popularity. They respond directly to three key local pressures: an ageing population, rising housing costs, and strong multigenerational living traditions across many of the city’s largest communities.

What was once considered a “nice-to-have” is now a practical and affordable solution, helping families create private, self-contained spaces for ageing parents or adult children while remaining connected on the same property.

The Fastest-growing age group is 65+

ABS-aligned projections show Australia’s 65+ population will grow from 4.31 million in 2021 to around 6.66 million by 2041, with a significant share concentrated in Melbourne’s expanding suburban areas.

Adult children priced out of independent homes

As of 2025, Melbourne’s median house price sits around the one million mark, contributing to a surge in adult children staying in or returning to family homes.

Multicultural multigenerational norms

According to the 2021 Census, nearly 40% of Melbourne residents were born overseas, with large Indian, Chinese, Vietnamese, and Greek communities, groups where multigenerational living is common. This makes granny flats a culturally aligned housing solution.

What Granny Flats Actually Solve for Modern Melbourne Households

Seen as a viable solution to the pressures facing modern Melbourne households, granny flats now effectively reshape how families live and manage money across generations.

Housing Elderly Parents Without a Nursing Home

Granny flats let families keep older parents close while still preserving their independence. It avoids the need for early entry into aged-care facilities. A self-contained unit on the same block provides a natural intermediate step, offering a private kitchen, bathroom, bedroom, and living space that’s just metres away from the main household.

Affordable Housing for Adult Children

With housing prices skyrocketing, many adult children simply cannot afford to enter the market. However, a granny flat allows parents to effectively subsidise their children’s housing by providing a low-cost home that’s right on the family block, all without the stigma of permanent “couch-surfing”.

Rental Income to Help With the Mortgage

A well and thoughtfully designed granny flat can typically rent anywhere from mid-1000s to low-2000s per month, depending on suburb, size, and finish. For many families, this extra stream of income can help offset mortgage and other cost-of-living payments.

Long-Term Multigenerational Living

Melbourne’s large Vietnamese, Indian, Chinese, and Greek communities frequently favour multigenerational living as a cultural norm, and granny flats offer a compromise between privacy and proximity. Rather than forcing three generations into one cramped house, families can place grandparents or adult children in a separate unit while still sharing meals, childcare, and day-to-day support.
