Home Extensions Berowra Heights
Built For The Way You Live
Berowra Heights is home to a mix of original 1960s and 70s brick homes alongside newer builds from the 80s and 90s, many sitting on generous blocks backing onto bushland or national park. These older homes typically feature three bedrooms and single living areas that no longer suit modern family life. Rather than selling and losing your bushland setting, a well planned extension transforms your existing home into the space you need.
We’ve completed extensions across Berowra Heights and surrounding suburbs like Mount Colah and Berowra, working with the sloping blocks and bushfire prone land requirements common to this area. Our team understands the local council requirements and how to design additions that respect the natural landscape while maximising your living space. Every project is managed by licensed builders who know the Upper North Shore inside out.
Families move to Berowra Heights for the bush setting, quality schools, and peaceful lifestyle, but that often means compromising on older home layouts. Property values in the area have climbed steadily, making it far more cost effective to extend your current home than to buy something larger. A quality extension not only gives you the extra space but significantly increases your property value in this tightly held suburb.

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 Berowra Heights?
Most extensions in Berowra Heights require either a Development Application or Complying Development Certificate from Hornsby Council.

Our team manages the full approval process for you, from initial plans through to final certification.
Can you extend homes on sloping blocks in Berowra Heights?
Absolutely. Many homes in Berowra Heights sit on sloping sites, and we’ve completed numerous extensions on challenging terrain throughout the area.

We handle all structural engineering and footings required for sloping block extensions.
