Reasons to love where you live with large scale home renovations in Sydney

Love where you’re living but need more space? We can help. We’ve completed over 300 home extensions throughout Sydney and beyond and our expert designers and builders will work with you to create a custom home extension that allows you to stay where your memories were made with enough room to grow.


Avoid the hassle of moving house
Between finding a new property, negotiating prices, completing paperwork and physically packing and moving your whole life to a new home, moving can be a real pain. By adding an extension to your Sydney home you can avoid the stress of moving while gaining the space you need.


Stay in the community you love
When you renovate instead of moving you get to stay where your roots are. Your children can stay in their school, you can stay close to your friends and there’s no need to fuss over updating your address.


Invest your future
This is the home you want to settle down in. Make it comfortable for living now and enhance its value for when it’s time to downsize further down the road.


Enhance your lifestyle
Whether you want to add an extra storey or expand your property with additional rooms and entertaining spaces, a home extension will help you make the most of your space. Our designers will create a custom extension from scratch that meets all your unique requirements.


Stay where your memories were made
It can be hard to move on from a home that holds so many precious memories — so why not stay there? With an extension, you can accommodate your growing family and cater to their changing needs, all while staying in the place where your precious memories were made.


Add value to your home
Beyond enhancing your home living now, an extension can also increase the value of your home. Improve the value of your home while keeping a mortgage you can afford that allows you the freedom to live the lifestyle you want.


Fast, hassle-free extensions with experienced Sydney renovation builders

One of the hardest things about planning a home extension in Sydney is the time spent sourcing builders, designers and contractors and waiting for quotes to come back. With Cubitt’s, we’ll shoulder that burden for you. Working with Cubitt’s is as simple as telling us exactly what you want and leaving it up to our in-house team of designers, builders and trusted contractors to make it happen. We have dedicated in-house staff who can prepare your estimate in a matter of days, rather than a matter of weeks, so we can get the green light on your project, fast.

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!"
