How can a granny flat add value to my property?

Granny flats add value to your property in more ways than one. Building a granny flat isn’t just a great way to accommodating a family member, it also presents a short or long-term rental investment opportunity, a home office solution or a comfortable guest house.

Pool Houses
Rental Units

Start living like you’re on a permanent holiday.

A pool house is one of the best improvements you can make to your property, and it’s not just about resale value either (though it improves that as well). A pool house brings immediate value to your lifestyle as well! Use it as your poolside entertainment hub, a kitchenette for events, a changing room to save your floors, and a comfortable guest accommodation for friends and family.

Turn your backyard into a smart investment.

Western Australia’s economy is booming, but Perth still offers surprisingly affordable property. With buyers and investors flocking here, it’s the perfect time to capitalise. Turn your backyard into a revenue stream with a rental-ready granny flat.

Client stories

Treeby

Jasmine & Owen

As first time home-owners and first time builders the most important thing for us was building with someone we could trust and who we knew would support us along the way. Chris gave us this reassurance and he was true to his word - he helped us at every step of the journey and we are so grateful for his guidance.
