Home Extensions Lansdowne
Built For The Way You Live
Lansdowne features a mix of fibro cottages and brick homes built from the 1950s through to the 1980s, mostly sitting on generous 550 to 700 square metre blocks. These older homes often have small kitchens, limited living space and cramped bathrooms that no longer suit modern family life. With good bones and plenty of land to work with, these properties are perfect candidates for a well designed extension.
We’ve completed dozens of extensions throughout Lansdowne and nearby suburbs like Canley Vale and Fairfield Heights, adding modern living spaces to homes that desperately needed them. Our team knows the local housing stock inside out, from the weatherboard workers cottages to the brick and tile homes that line the streets off The Horsley Drive. We handle all the structural engineering, council approvals and building work so you can stay living in your home while we transform it.
Lansdowne sits close to schools, shopping along The Horsley Drive, and offers easy access to the M4 and M7 motorways for commuters. The property market here rewards renovated homes, with extended properties often fetching $150,000 to $200,000 more than unrenovated equivalents on similar blocks. A properly planned extension gives your family the space you need while building serious equity into your property.

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!"

We provide a detailed timeline as part of your quote so you know exactly what to expect.
Do I need council approval for a home extension in Lansdowne?
Most extensions in Lansdowne require either Development Approval or a Complying Development Certificate from Fairfield Council. Some smaller additions under 30 square metres might qualify as exempt development, but this depends on setbacks and other planning controls. We handle the entire approval process for you, working with experienced drafters and certifiers who know the local requirements.
Can you extend older fibro homes in Lansdowne?
Absolutely. Many of the fibro and weatherboard homes in Lansdowne are structurally sound and can be extended with the right approach. We assess the existing structure, reinforce where needed, and design the extension to blend with or update the existing home. Our team has extended dozens of these older style homes throughout the area.
