Home Extensions Lane Cove
Built For The Way You Live

Lane Cove is packed with post war homes and 1960s brick houses on generous blocks, many around 600 to 800 square metres. These older homes often have small living areas and dated floor plans that don’t work for modern families. An extension makes far more sense than moving, especially when you’ve already got a great location and good bones to work with.

We’ve completed extensions right across Lane Cove, from single storey rear additions to full second storey builds. Our team knows the local council requirements and works with Lane Cove families to create extra space without losing the backyard. From Mowbray Road to River Road and everywhere in between, we’re building extensions that actually improve how people live in their homes.

Lane Cove’s tight property market means many families want to stay put rather than upsize elsewhere. Adding a second storey or extending at the rear can give you the extra bedrooms, bigger kitchen or proper living space you need. A well planned extension protects your investment and saves you the huge cost and stress of selling and buying in this area.

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!"
