Visit our showroom to see why Granny Flats are the perfect fit for the beautiful Wollongong and Illawarra region.

If you live in the Wollongong and Illawarra regions, building a Granny Flat on your property is one of the savviest investments available. Whether you are retiring to the stunning South Coast of NSW or just setting up your first home, many locals are choosing Cubitt’s to add value to their properties. Plus, these days with the launch of companies such as Airbnb or Stayz, there are more opportunities to maximise property revenue than ever before. If you are at a stage of your life where you are wanting to spend less time in the office and more time at home with your family, you can reduce or replace your number of working hours with passive income from building a new Granny Flat.
