Why Build a Granny Flat?
A secondary dwelling (granny flat) is one of the smartest ways to unlock more value from the land you already own, without the cost of moving, selling, or buying a bigger property.
How can a granny flat make a difference to your property?
1) Add Living Space for Family
A granny flat gives adult children, parents or guests their own private space — close enough to support each other, but with full independence and privacy.
4) Provide More Options for Your Family
Granny flats give families more living flexibility — whether it’s space for parents, adult children, guests, or downsizing within your own block. They also help create more affordable living options in high-demand areas.
2) Create Extra Income
A well-designed granny flat can become a stable rental income stream. Many homeowners use this extra income to reduce mortgage pressure, cover household bills, or accelerate savings
5) Cheaper Than Upsizing
Instead of selling and buying a bigger home (and paying stamp duty, agent fees, moving costs), many families stay where they are and simply build up to 80m² at home.
3) Increase Property Value
A professionally built secondary dwelling can significantly increase property value. Buyers love the flexibility — which makes your home more attractive if you sell in the future.
6) Flexible Use Over Time
Granny flats adapt as life changes — home office, studio, teenage retreat, guest house, hobby room, student accommodation, anything.
