Need more space but love your home? Cubitt’s offer personalised, affordable and stress-free solutions for growing families.

As your family changes, you might find your existing home is no longer enough to provide the functional space you need. But many Australians consider it to be a time-consuming and expensive process to buy and sell your home, do all the cleaning and paperwork required, negotiate terms not to mention packing and physically moving location!

Stay in the family home where your most treasured memories have been created and shared, all while boosting the value of your existing property and achieving the extra space you need. Cubitt’s is passionate about helping Australians create their perfect living space, and can provide flexible solutions catered to your budget, property specifications and needs.

Does your property have limited land to build on? Cubitt’s Granny Flats can be built on as little space as 30m2! We have perfected the design of a compact yet comfortable 1-Bedroom Granny Flat model that works within a limited area. Alternatively, a custom-designed home extension or first-floor addition may be the perfect solution to keep your family together, without having to change schools or navigate the rocky property market.

Restricted by a narrow or sloping block of land? Ian Cubitt’s Classic Home Improvements have been building Granny Flats and home extensions in Australia for over 25 years, and are the experts on navigating difficult blocks.

Perhaps you have a particular floorplan or design in mind? Unlike most other companies, Cubitt’s offers custom Granny Flats built entirely to suit your needs and lifestyle.
