Home Extensions Longueville
Built For The Way You Live
Longueville is filled with Federation homes and Californian bungalows from the 1920s and 1930s, sitting on decent sized blocks with generous backyards. These older homes often have small kitchens, limited living space and outdated layouts that don’t suit modern family life. An extension is the smart way to add space without leaving this quiet peninsula suburb.
We’ve completed extensions across Longueville and throughout Lane Cove, Greenwich and the lower North Shore, working with the character of older homes while creating practical modern spaces. Our team understands the local council requirements and knows how to design additions that complement Federation and interwar architecture. Every project is managed by our licensed builders from concept through to completion.
Longueville’s tightly held property market means homeowners tend to stay put and improve rather than move. With the suburb’s excellent schools, waterfront position and quiet streets, adding a quality extension makes more sense than trying to find something bigger nearby. A well designed addition adds serious value and gives you the home you actually need.

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!"
