Granny flats are becoming a popular option for Australian homeowners looking to maximise their property's potential without the high costs of a full extension or new build. Whether you want to accommodate aging parents, support adult children, or generate rental income, granny flats offer an affordable, flexible solution. This guide covers everything you need to consider before investing in a granny flat and how Express Portables can help.
1. What Is a Granny Flat?
A granny flat is a self-contained, secondary dwelling located on the same lot as a primary home. These compact units typically include a bedroom, bathroom, kitchen, and living area, making them ideal for independent living. Traditionally used to house elderly family members, modern granny flats now serve a variety of purposes including home offices, guest retreats, or rental properties.
At Express Portables, our granny flat alternatives such as Expander Homes are designed to suit your lifestyle while maintaining affordability, ease of setup, and style.
2. Understanding Local Regulations
Before purchasing or building a granny flat, it's essential to research local council regulations. Requirements can vary depending on your location and may dictate permissible size, placement, usage, and occupancy limits. Some areas allow granny flats to be rented out, while others restrict use to family members.
We recommend checking with your local council or working with experienced providers like Express Portables to ensure your chosen portable home solution aligns with zoning and development codes. Many of our customers successfully place units in regional and rural locations with fewer planning constraints.
3. Costs of Buying a Granny Flat
The price of a granny flat depends on size, layout, features, and level of customisation. While traditional brick builds can cost upwards of $150,000, prefabricated options from Express Portables offer more budget-friendly solutions.
Our Expander Homes start at $21,900, with larger two- or three-bedroom models available for under $60,000. Don’t forget to factor in delivery, installation, permits, and utility connections into your overall budget. We also offer finance options to make purchasing easier.
4. Design and Customisation Options
Granny flats come in a wide range of designs. From studio layouts to spacious two- and three-bedroom options, the possibilities are endless. Choose from a variety of portable cabins and homes with modern finishes, integrated kitchens, and bathrooms.
Express Portables offers customisation across colours, flooring, wall finishes, and layout options. Whether you're after open-plan living or separate rooms for privacy, our team helps tailor your design to your needs—whether for an elderly parent, adult child, or tenant.
5. Benefits of a Granny Flat
Extra Income:
If local regulations allow, renting out a granny flat can provide reliable supplementary income. In areas with high demand, it can cover the cost of your investment in just a few years.
Property Value:
Adding a granny flat-style home increases your property's resale appeal. Dual living potential is attractive to investors and growing families.
Multigenerational Living:
Keep family close without sacrificing privacy. Granny flats offer a comfortable, separate space for relatives while maintaining proximity for support and care.
Flexible Use:
Beyond accommodation, these units can serve as home offices, creative studios, teen retreats, or even Airbnb rentals. Their versatility ensures long-term value.
6. Considerations Before Buying a Granny Flat
Space and Access:
Make sure your property can accommodate a granny flat comfortably. Consider yard space, privacy buffers, and access for deliveries and construction.
Utilities and Infrastructure:
You may need to connect to existing services like water, electricity, and sewerage. Express Portables can guide you on site prep and service integration.
Privacy and Layout:
Thoughtful positioning, fencing, and landscaping can help ensure privacy for both the main residence and the granny flat occupants.
Maintenance:
While low-maintenance, these units still require occasional servicing, cleaning, and care, especially if rented out.
