Home Extensions Kirribilli
Built For The Way You Live
Kirribilli’s housing stock is mostly Federation and interwar homes built on smaller blocks, many between 250 and 400 square metres. These charming older homes were built for a different era, and most families today need more space for modern living. With land prices what they are in this harbourside location, extending your existing home makes far better financial sense than trying to find something larger.
We’ve completed dozens of extensions throughout Kirribilli and the lower North Shore, from single storey rear additions to full second storey builds. Our team knows how to work with the period features of Federation and interwar homes while creating open plan living spaces that families actually want. We handle everything including structural engineering, council approvals, and coordination with all trades through to final handover.
Kirribilli homeowners are holding onto their properties longer given the location and proximity to the city. Most families would rather renovate and extend than move, especially with stamp duty and the shortage of family sized homes in the area. A well designed extension not only gives you the space you need today but adds serious value to your property in one of Sydney’s tightly held suburbs.

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."

Some smaller alterations may be exempt, but anything substantial needs approval. We manage the entire approval process for you, working with our design team and certifiers to get your extension approved as efficiently as possible.

Absolutely. We’ve extended plenty of Federation and interwar homes throughout Kirribilli and know how to respect the character of these properties.
