Time for an upgrade? If you’re ready to turn your current home into your dream home, we’re ready to help! With experienced local builders on hand and a network of trusted suppliers, we can get your renovation underway in no time.


Save yourself the stress of moving
Moving house is known to be one of the most stressful experiences people can go through, and navigating the volatile Australian housing market to find a new property can be nothing short of exhausting. Between finding a house that’s the right size and price, completing paperwork and packing your life into boxes, you can expend endless time, energy and money on moving home – all of which can be saved by adding an extension to your Canberra home.


Stay connected to your community
Choosing to extend rather than move means not having to uproot your family and start again. Your kids can stay at their school and you can stay connected to your friendship network and family members. Plus, there’s no need to find new doctors, hairdressers, dentists and other service providers, and no need to update your address.


Enjoy today, invest in tomorrow
You already love where you live, now you need to ready your home for the future. Make your home spacious and comfortable for family living now and add value to your property for when it comes time to sell or downsize in the future.


Upgrade your lifestyle
With the help of our expert design team, you can turn your current home into your forever home with a custom extension. Whether you want to make room for your growing family, want more space for entertaining or need a parent’s retreat to escape to, our design team will come up with a bespoke design that ticks all the boxes while working to your budget.


Stay connected to precious memories
When you’ve spent years creating family memories in your home it can be heart-wrenching to move – that’s why so many Canberra locals are choosing to extend instead. A custom extension can turn your family home into your forever home, helping you stay together with room to grow. Hold onto your memories and make new ones in your new and improved home.


Increase the value of your property
Adding an extension to your home can increase its value by tens or even hundreds of thousands of dollars. Not only will you enjoy more room to live, play and relax, you’ll also enjoy higher value when it comes time to sell – all while keeping a mortgage you can afford.

Hear What Cubitt’s Customers Have to Say…

"Cubitt’s are the most supportive and professional contractors I have ever employed. From their on-site supervisor to all others who worked on site, everyone was co-operative, nothing seemed to be too much trouble, and any alterations we wanted were carried out quickly and well. The job was completed 2 months before the contract date, and we are very happy with the end result. We would happily recommend Cubitt’s to anyone considering this option!"
