Home Extensions Campsie
Built For The Way You Live
Campsie has a solid mix of brick homes and older style semi detached dwellings, many built from the 1950s through to the 1980s on modest blocks averaging 450 to 600 square metres. These homes were built for smaller families and often lack the extra bedrooms, open living spaces or modern kitchens that families need today. Rather than moving away from the area, many homeowners are choosing to extend and create the space they need right where they are.
We work with families across Campsie who need more room but want to keep their location near schools, shops and transport. Whether it’s adding a second storey to capture more space without losing yard, or extending at the rear for an open plan kitchen and living area, we design each project around how you actually live. Our team also handles plenty of extensions in Belmore, Canterbury and Lakemba where the housing stock and family needs are very similar.
With Campsie station right there and good access to parks and local shops, families want to stay in the area long term. Property values have climbed steadily over the past decade, and a well planned extension delivers real returns when it comes time to sell or refinance. Adding a quality extension means you get the home you need without the hassle and cost of selling, moving and buying again in an expensive market.

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!"
