6 Month Build Time Guarantee
Our granny flat build times have been significantly reduced from 12 months to just 6 months. We’ve achieved this by adopting an innovative construction approach that utilises steel framed construction instead of traditional double brick. This streamlined method allows us to complete your build faster, so you can move in sooner—whether it’s to settle in with loved ones, set up a new office space, or begin renting it out and enjoying the returns on your investment.

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. A pool house brings immediate value to your lifestyle as well! Use it as your poolside entertainment hub, a kitchenette for parties, a changing room after a swim, or a comfortable guest house 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.
