Live where you love 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 in 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.

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.

  • 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.

Make the House you Live in Now, your “Forever Home”

A custom-designed extension or first-floor addition from Cubitts creates value from the day you meet with one of our Design Consultants. Keep your family together, with the freedom of space. Preserve the home you treasure and make room for your own style choices. Make this home your “Forever Home”

Frequently Asked Question on Granny Flats (1)

I thought granny flats had to be a maximum of 60m2. Why does Cubitt’s have bigger models?

The 60m2 requirement applies only to the interior space of your granny flat. Additional areas such as decks, alfresco areas and garages are not included in this area requirement.

To find out more, talk to one of our experienced design consultants today

Are you guys the most expensive granny flat builders?

No, not by a long shot. Our granny flats are incredibly affordable, and we always keep your budget in mind when considering options for you.

And don’t forget, in addition to your actual build we offer unbeatable customer service. No excuses. Our motto is: one contact, zero confusion. Our highly trained staff are always available, from our design team through to the office team, your site supervisor and construction team. There is no compromise on skills and customer service at Cubitt’s.

Will I need survey reports before building can start?

Survey reports (bushfire, flood etc) are a drag. But they ensure your safety and your warranty, so they are worth doing and doing well.

We are completely transparent with you from the start about the reports you’ll need, and the costs involved. Better you know up front, and we can support you in understanding the reasons for these and the process to get moving on your build.
