The beauty of a Granny Flat lies in its versatility. Whether you’re building a Granny Flat to make more space for your family or building a Granny Flat as an investment, it can truly enhance your lifestyle. Here are just some of the uses our Granny Flat plans care being put to.

Guest quarters

Whether you have interstate or international family members visiting regularly or want to have a self-contained area for your friends to stay in, a custom granny flat is a smart solution. Provide a comfortable, private environment with a kitchen, bathroom and living area for long-stay guests to give both them and you some privacy. 


Safe elder housing

Provide yourself with an extra revenue stream with a purpose-built Airbnb granny flat. We can incorporate desirable features that will make your property more enticing to potential holidaymakers and people on business such as floor to ceiling windows, strong wifi, spacious lounge areas and study nooks.


Grey nomad home base

If you’re looking to retire soon and want to have an inexpensive yet comfortable home base to return to, a custom granny flat is a fantastic choice. Invest more of your money into funding your retirement lifestyle by adding a granny flat to your child’s property.


Pool house

Provide a comfortable place for guests to relax, eat, drink and bathe when using your pool. We can add a custom spacious covered deck, outdoor kitchen for entertaining and handy shower facilities to make your pool going guests feel right at home. Plus we can use tile, laminate or wooden flooring inside your flat suitable for wet-footed visitors.


Stepping stone home

Get a foot on the property ladder by investing in a granny flat on your parent’s property. Stay close to the comforts of home while funnelling your hard-earned money into an investment rather than losing it to rent, all while staying in a brand new, clean, comfortable space that’s all your own.
