Home Extensions Glen Alpine
Built For The Way You Live

Glen Alpine is dominated by modern brick veneer homes built from the late 1990s through to the 2010s, mostly sitting on compact 450 to 600 square metre blocks. Many of these homes were built to a standard developer layout with three or four bedrooms, and as families grow or work from home becomes permanent, the need for extra space becomes urgent. An extension makes far more sense than moving, especially when you’ve already established yourself in this tight knit community.

We’ve completed extensions throughout Glen Alpine and the surrounding Campbelltown area, working with the typical brick and tile homes that define this suburb. Our team understands the local building styles and how to match existing materials and rooflines so your extension looks like it was always part of the original home. From single room additions to full ground floor extensions and second storey builds, we’ve done it all across Glen Alpine and neighbouring suburbs.

Glen Alpine attracts young families who want modern, low maintenance living with good access to schools and the M5. Property values have climbed steadily, and a well planned extension can add significant equity while giving you the extra bedroom, home office or open plan living area your family actually needs. With land prices what they are, extending your current home is often the smartest financial decision you can make.

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!"
