Why Aussies are falling in love with Granny Flat
Granny flat trends: Why more Aussies are building secondary dwellings
Over the past two years, the popularity of granny flats has surged across Australia. These compact, self-contained dwellings offer flexibility, functionality, and the ability to meet a range of modern living needs — all while adding value to your property.
If you’re considering building one, here are some of the most common and practical ways families are using their granny flats today:
1. Generate extra income
One of the top reasons homeowners build granny flats is to rent them out for additional income. Whether you’re leasing to tenants, students, or short-term renters, it can provide a steady revenue stream that helps pay off your mortgage or fund other expenses.
A rental granny flat may offer tax depreciation benefits — a valuable bonus come tax season.
2. A smart retirement plan
With more baby boomers approaching retirement and adult children living at home longer, multigenerational living is rising. A granny flat provides a private and practical solution for ageing parents or even retirees themselves.
It allows you to stay close to family while maintaining independence and privacy — a win-win for everyone.
3. The modern “man cave” (or she shed!)
Sometimes, we all need a space to unwind and disconnect. Granny flats are increasingly being transformed into personal retreats — the perfect spot to relax, pursue hobbies, or entertain guests without disturbing the rest of the household.
From gaming rooms to home gyms or studios, the possibilities are endless.
4. A productive home office
With flexible and remote work becoming the norm, more professionals are setting up their home office in a granny flat. It creates a dedicated workspace separate from the main house, boosting focus and productivity while still being close to home.
Whether you’re running a business or need a quiet spot for virtual meetings, it’s a smart investment in your work-life balance.
5. The importance of costing your granny flat project
Before you break ground, it’s crucial to get a detailed and realistic cost estimate for your granny flat project. Costs can vary depending on design, site conditions, materials, and council regulations.
Partnering with a qualified Quantity Surveyor can help you:
-
Avoid budget blowouts
-
Understand material and labour costs
-
Identify cost-saving opportunities
-
Meet council or bank reporting requirements
-
Plan for long-term return on investment
A well-costed project ensures you stay within budget and avoid surprises — whether you’re building for rental income, family needs, or future resale value.
