Home Extensions Berowra
Built For The Way You Live
Berowra is filled with homes built mainly from the 1970s through to the 1990s, sitting on generous bush blocks that back onto national park or bushland reserves. Many properties here are single storey brick homes with dated layouts that no longer suit how families live today. An extension makes perfect sense when you’ve got the land, the location, and a home that just needs reconfiguring to work properly.
We’ve completed extensions throughout Berowra and neighbouring areas like Cowan and Mount Kuring-gai, working with the sloping blocks and bushfire regulations common to this part of Sydney. Our team understands the local council requirements and how to design additions that respect the natural surroundings while giving you the extra space your family needs. Every project is different, but the goal is always the same: make your home work better without losing what you love about living here.
Families stay in Berowra for the schools, the space, and the community feel that’s hard to find closer to the city. The property market here rewards homes that have been thoughtfully updated, and a well designed extension can add serious value while letting you avoid the stress and cost of buying and moving. When you’re already in the right suburb on a great block, extending makes more sense than starting over somewhere else.

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."

FAQS
Got a question?
How much does a home extension cost in Berowra?
A single room addition typically starts from $80,000, while a full ground floor extension usually begins around $150,000. Second storey additions generally start from $250,000 depending on size and finishes. We provide a free quote after discussing your specific needs and assessing your property.
How long does a home extension take in Berowra?
Most home extensions take between 3 to 6 months from council approval through to final handover, depending on the scope and complexity of the work. The approval process itself can add another 8 to 12 weeks before construction starts. We’ll give you a realistic timeline during the quoting process so you can plan accordingly.
Do I need council approval for a home extension in Berowra?
Most extensions require either a Development Application or Complying Development Certificate through Ku-ring-gai Council in NSW. The requirements depend on the size and nature of your extension, plus any bushfire or environmental overlays on your property. Our team manages the full approval process for you, liaising with certifiers and council as needed.
Can you extend homes on sloping bush blocks?
Absolutely. Many Berowra properties sit on sloping blocks with bushland at the rear, and we’ve designed extensions for these conditions many times. The key is working with the natural fall of the land and meeting bushfire attack level requirements where they apply. We’ll assess your block during the initial consultation and design an extension that suits the terrain.
