Home Extensions Seven Hills
Built For The Way You Live
Seven Hills is filled with solid brick homes from the 1970s and 1980s, sitting on decent sized blocks between 550 and 700 square metres. These homes were built for smaller families with compact living areas, limited storage and often just one bathroom. An extension makes perfect sense when the bones of the house are good but the layout no longer works for modern family life.
We’ve completed dozens of extensions throughout Seven Hills and neighbouring suburbs like Lalor Park and Toongabbie, adding second storeys, opening up ground floor living areas and creating proper master suites. Every project starts with understanding how you actually use your home and what’s not working right now. Our team knows the local building conditions, council requirements and what works best for the housing stock in this area.
Seven Hills offers great value compared to suburbs closer to the city, which is why so many families are choosing to extend rather than sell and move. The schools are good, the location is central to Parramatta and Blacktown, and you’re already established in the community. A well planned extension can add $150,000 to $300,000 in value while giving you the extra space your family needs without the stress and cost of moving.

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!"

A single room addition might take 3 months, while a full second storey could take 5 to 6 months. We provide a clear timeline during the planning phase and keep you updated throughout the entire build.
Do I need council approval for a home extension in Seven Hills?
Most extensions in Seven Hills require either a Development Application or Complying Development Certificate from Blacktown Council. Some minor additions under 10 square metres might qualify as exempt development, but this is rare. Our team manages the entire approval process for you, liaising with council and certifiers to get your project approved as quickly as possible.
Can you extend 1970s brick homes in Seven Hills?
Absolutely, we extend 1970s and 1980s brick homes all the time in Seven Hills. These homes are structurally sound and sit on generous blocks that can easily accommodate extensions. The key is matching the brickwork and ensuring the new addition ties in properly with the existing roofline and foundation.
