Home Extensions Woronora Heights
Built For The Way You Live

Woronora Heights is home to predominantly brick and tile houses built from the 1970s through to the 1990s, sitting on generous blocks that often exceed 600 square metres. Many original homes feature three bedrooms and single garages that no longer suit growing families or modern living requirements. The good block sizes and solid construction make these homes perfect candidates for extension rather than selling and moving.

We’ve completed extensions throughout Woronora Heights and neighbouring suburbs like Woronora and Bangor, working with the sloping terrain that’s common in this part of the Shire. Our team understands the local building requirements and how to design extensions that work with the natural fall of these elevated blocks. Whether it’s adding a second storey to capture better views or extending at ground level, we handle all council requirements and site challenges.

Families choose Woronora Heights for the quiet streets, quality schools and bushland setting, so extending the family home makes more sense than uprooting to find extra space. The local property market remains strong, and a well designed extension typically adds more value than the construction cost. Most homeowners here prefer to invest in their existing property rather than face the expense and disruption of moving to a larger home.

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."

"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!"

Do I need council approval for a home extension in Woronora Heights?

Some minor additions may qualify as exempt development, but this depends on specific measurements and setbacks. We assess your project, prepare all documentation and manage the full approval process on your behalf.

Can you extend homes on sloping blocks in Woronora Heights?

Yes, we regularly work with the sloping blocks that are common throughout Woronora Heights and the surrounding area. Our designs account for the natural fall of the land, managing drainage and structural requirements to suit the terrain. Many of these sites actually offer great opportunities for lower level extensions or improved outdoor living spaces.
