Home Extensions Woronora
Built For The Way You Live
Woronora is filled with post war homes and brick houses from the 1960s and 70s, many sitting on large blocks backing onto bushland or the Woronora River. These homes often have smaller living spaces and dated floor plans that no longer suit how modern families live. An extension makes far more sense than selling and moving, especially when you’ve already got the land and location sorted.
We’ve completed extensions across Woronora and neighbouring suburbs like Bonnet Bay and Sutherland, working with the sloping blocks and bushland settings that make this area unique. Our team knows how to design additions that respect the local character while giving families the extra bedrooms, open plan living or second storey views they’re after. Every project is tailored to the specific home and how the family actually uses their space.
Families move to Woronora for the bush setting, good schools and river access, so most people want to stay put rather than uproot to get more room. With median house prices continuing to climb across the Shire, extending your current home is a smart investment that gives you the space you need without the hassle and expense of moving. A well designed extension can add serious value while letting you keep the lifestyle and location you already love.

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."

How long does a home extension take in Woronora?

The exact timeline depends on the size and complexity of your project, along with any site constraints like sloping blocks or bushfire prone land requirements. We’ll give you a clear timeline during the planning stage so you know what to expect.
Do I need council approval for a home extension in Woronora?
Yes, most extensions in Woronora require either a Development Application or Complying Development Certificate through Sutherland Shire Council. The approval pathway depends on the size of your extension and whether it meets certain planning controls. We manage the full approval process for you, including all drawings, paperwork and council liaison.
Can you extend homes on sloping blocks in Woronora?
Absolutely. Many Woronora properties sit on sloping blocks, and we’ve designed and built plenty of extensions that work with the natural fall of the land. Depending on your site, we can incorporate split levels, underfloor storage or even take advantage of the slope to add a lower level. Our team assesses your specific block during the initial consultation to recommend the best approach.
