1 bedroom Granny Flats for every purpose

Home office

As working from home becomes more and more common, many of us are looking for a comfortable and affordable home office solution. A granny flat makes a convenient working from home option with the commute across the back lawn offering a psychological separation of work and home and providing clarity and calm for the workday.


Artist Studio

Create your own dedicated, unique space for painting, building and creating. A self-contained studio granny flat is a great choice for a creative space, providing all the room you need for your creative endeavours. With custom features like a deep sink for washing brushes and other art supplies, a dark room for photography or in-floor drainage for easy cleaning, we can create the ultimate artistic space for your studio.


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. 


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.


Teenagers retreat

As your kids mature they’ll naturally start to want their own space. A teenagers retreat can provide some privacy for them and some peace and quiet for you. Kit it out with a gaming room and private lounge room and add bunk beds for when friends sleepover.


Man cave

Create the ultimate bloke’s retreat with a gaming station, bar, lounge room or whatever you like with a custom granny flat. Our architectural granny flat designs can be tailored to fit a pool table, kitchen-bar area or whatever you’ve got in mind, the only limit is your imagination.


Safe elder housing

As your parents age it can become increasingly difficult for them to keep up with home maintenance, and with the added risk of falls or accidents, it can be hard not to worry about their safety. A granny flat offers a safe, comfortable, affordable alternative to nursing home accommodation and lets you keep your family close while still allowing them their independence.
