Home Extensions Berowra Waters
Built For The Way You Live
Berowra Waters is defined by its waterfront homes and bushland properties built predominantly from the 1960s through to the 1990s on large, sloping blocks. Most homes sit on 700 to 1500 square metre sites with spectacular water or bush views that deserve to be captured. These older homes often have smaller living areas and dated layouts that don’t work for modern family life, making a well designed extension the smartest way to add space while maximising those incredible views.
We’ve completed extensions throughout Berowra Waters and neighbouring waterside suburbs where site access and terrain present unique challenges. Our team understands how to work with steep blocks, narrow water access points, and the heritage and environmental considerations that come with building in this protected area. Every project is carefully planned to respect the natural surroundings while creating functional, beautiful living spaces.
Property in Berowra Waters commands premium prices thanks to the waterfront location and natural beauty, with many families choosing to extend rather than relocate. A thoughtfully designed extension that opens up living areas and takes advantage of water views can add considerable value while maintaining the peaceful lifestyle that drew you here. With limited housing stock and strong demand, investing in your existing home makes both lifestyle and 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."
