Home Extensions Old Toongabbie
Built For The Way You Live

Old Toongabbie has a solid mix of original fibro and brick homes from the 1960s and 70s, sitting on decent blocks that give you room to extend. Many properties here are on 550 to 650 square metre blocks, which means there’s real potential to add a second storey or push out the back without losing your backyard. These older homes were built with smaller rooms and limited living space, so an extension makes complete sense for modern families.

We’ve completed extensions right across Old Toongabbie and neighbouring areas like Toongabbie and Seven Hills, working with families who need more space but want to stay in the area. Our team knows the local building requirements and how to work with the older housing stock here, whether that’s dealing with original stumps, asbestos removal or matching brickwork. Every project is managed in house from design to handover, so you’re dealing with one team the whole way through.

Old Toongabbie offers good value compared to suburbs closer to the city, and families are choosing to renovate and extend rather than move. The schools, parks and train access make it a practical location for growing families who just need more room. A well planned extension can add serious value to your property while giving you the extra bedrooms, living space or home office you actually need.

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!"

The approval pathway depends on your property, the size of the extension and local planning controls. We manage the full approval process for you, working with certifiers and council to get your extension approved.

Can I build up on my Old Toongabbie home?

Yes, most Old Toongabbie homes are suitable for a second storey addition, especially the solid brick homes from the 60s and 70s. We assess the existing structure first to confirm the foundations and frame can support the additional load. Adding a second storey is often the best option when you want more space but need to keep your backyard.
