Home Extensions Kurnell
Built For The Way You Live
Kurnell homes are predominantly single storey brick and fibro builds from the 1960s through to the 1980s, sitting on decent blocks that typically range from 550 to 750 square metres. Many of these original homes feature small living areas, single bathrooms and cramped kitchens that no longer suit modern family life. An extension makes far more sense than selling up, especially when you’ve got a solid home on a good sized block in a beachside location.
We’ve completed extensions throughout Kurnell and nearby suburbs like Cronulla and Lilli Pilli, working with homeowners who want to stay in the area but need more space. Our team understands the local housing stock and what works best for these solid but dated homes. Whether it’s opening up the back of the house, adding a second bathroom or creating a proper master suite, we design extensions that feel like they’ve always been part of the home.
Living at the southern tip of the Shire means beach access, national park trails and a tight community feel that’s hard to find elsewhere in Sydney. Property prices have climbed steadily as more families discover what locals already know about the area. A well planned extension can add $200,000 to $400,000 in value while giving you the extra space you need without leaving a location you love.

Don't Take Our Word For It
"I contacted Monstructions to get an idea of a price for doing an extension on my home. Of course I contacted many other people but they were the only ones who came back to me and assisted in giving me an idea of the price. I was so grateful. I wouldn't hesitate in recommending this company as we couldn't be more happy with the team, thank you for your help and support."
Amanda
"We had a plan of what we wanted with our 2nd story + granny flat addition, but also had a budget to meet..the Monstructions team worked hard to make that happen for us. With a few little hiccups along the way from weather delays, the boys kept the job moving as smoothly as possible and the team were amazing in keeping mess to a minimum. Allowing us to stay at home during the reno. 100% highly recommended!"
Angela
"Fantastic! Monstructions did an amazing job on my home extension, all the boys that worked on my house were professional and polite, and their quality of work was second to none. From drawings to completion it was a breeze working with them. They were easy to work with and extremely efficient and professional. Thank you for all the hard work and effort, I will recommend you to everyone I know."

Do I need council approval for a home extension in Kurnell?
Most home extensions in Kurnell require either a Development Application or Complying Development Certificate through Sutherland Shire Council. Some minor internal alterations may be exempt, but any structural work or external addition typically needs approval. We manage the full approval process for you, from plans through to certification.
Can you extend older fibro homes in Kurnell?
Absolutely. Many Kurnell homes have original fibro construction that’s still structurally sound and perfect for extending. We assess the existing structure, upgrade where needed, and design the extension to blend with or modernise the existing home depending on your preference.
