Home Extensions Caddens
Built For The Way You Live
Caddens is a newer release area with most homes built from the late 1990s through to today, sitting on blocks typically between 450 and 600 square metres. Many families bought here for the affordability and space, but as kids grow or work from home becomes permanent, the standard project home layout often falls short. Adding a second storey or extending at the rear makes more sense than selling and starting again.
We’ve completed dozens of extensions across Caddens and neighbouring suburbs like Erskine Park and Claremont Meadows, working with the brick veneer homes common to the area. Our team understands the construction methods used by volume builders in this pocket, which helps us integrate new work properly with existing structures. We handle everything including engineering, council approvals, and all trades from start to finish.
Caddens attracts young families who want space without the premium price tag of older suburbs closer to the city. Property values here have climbed steadily, and a well designed extension can add significant equity while giving you the home you actually need. Most of our clients here are adding extra bedrooms upstairs or creating open plan living areas that the original builder never included.

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!"
