IS YOUR HOME READY FOR AN EXTENSION?
Monstructions specialises in home extensions Girraween, expertly designing and building additions that suit the homes and families throughout the Canterbury Bankstown & Western Sydney area.

Home Extensions Girraween
Built For The Way You Live
Girraween is filled with solid brick homes from the 1970s and 1980s, typically sitting on 550 to 650 square metre blocks. Many of these houses feature the original three bedroom layout with a single living area, which no longer suits growing families or modern working from home needs. An extension makes far more sense than moving, especially when you’ve already got good bones and an established neighbourhood.
We’ve completed dozens of extensions across Girraween and nearby suburbs like Greystanes and Pemulwuy, working with the typical brick construction that’s common throughout this area. Our team knows how to match existing brickwork, work within side boundary setbacks, and design additions that feel like they’ve always been part of the home. Whether it’s opening up the back for better indoor outdoor flow or adding a second storey, we handle the full scope from concept to completion.
Girraween families value the proximity to Westfield Parramatta, good schools, and the M4 access for work. Property values here have climbed steadily, and a well designed extension can add $150,000 to $250,000 to your home’s value while giving you the extra space you actually need. It’s a smart investment that lets you stay in the area you know without the stress and cost of selling and buying again.

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!"
