Home Extensions Belrose
Built For The Way You Live
Belrose is defined by its mix of original 1970s and 1980s brick homes on generous blocks, many between 600 and 800 square metres. These solid but dated homes often have small living areas, limited natural light and closed off floorplans that don’t suit modern family life. An extension is usually far more practical than moving, especially given the size of the blocks and the quality of the neighbourhood.
We’ve completed extensions across Belrose and nearby suburbs like Davidson and Frenchs Forest, working with the sloping blocks and bushland settings common to the area. Most of our clients want to open up their living spaces, add a second storey to capture views or create better connection to their outdoor areas. We know the local housing stock well and design extensions that complement the existing homes while improving functionality and light.
Belrose offers excellent schools, easy access to Westfield Warringah and the Northern Beaches Hospital, plus you’re only 20 minutes from the beach. Properties here hold strong value and a well designed extension can add significant equity while giving you the space your family needs. Rather than selling and paying stamp duty plus moving costs, most homeowners find extending their current home makes better financial sense.

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 Belrose?

We provide a free quote after assessing your property and understanding what you need from the space.
How long does a home extension take in Belrose?
Most home extensions take between 3 to 6 months from council approval through to final handover. The timeframe depends on the scope of work, weather conditions and any site access challenges. We’ll give you a realistic timeline during the quoting process and keep you informed throughout the build.
Do I need council approval for a home extension in Belrose?
Most extensions in Belrose require either a Development Application or Complying Development Certificate through Northern Beaches Council. There are specific planning controls and bushfire requirements in parts of Belrose that need to be addressed. We manage the entire approval process for you, working with our trusted consultants to get your extension approved.
Can you extend on a sloping block in Belrose?
Absolutely. Many Belrose properties sit on sloping blocks with bushland settings, and we’ve designed plenty of extensions that work with the natural fall of the land. The slope can actually work in your favour, allowing for better views, under house storage or split level designs. We’ll assess your site and show you the best options during the design phase.
