Home Extensions Auburn
Built For The Way You Live
Auburn has a solid mix of older brick homes from the 1960s and 70s alongside some weatherboard cottages on decent sized blocks, particularly around the quieter streets near Auburn Botanic Gardens. Many of these homes sit on 550 to 700 square metre blocks with good side access, making them ideal candidates for extensions rather than the upheaval and expense of moving. The bones are good in most Auburn homes, they just need more space for growing families or modern living areas.
We’ve completed extensions throughout Auburn and neighbouring suburbs like Lidcombe and Regents Park, working with the typical brick and tile homes that dominate the area. Our team knows how to match existing brickwork, work within setback requirements for these sized blocks, and design additions that feel like they’ve always been part of the home. We handle everything from single storey rear extensions to complete second storey additions for families needing serious extra space.
Auburn’s location with train access to Parramatta and the CBD means families want to stay put rather than move further out. Property prices have climbed steadily over the past decade, and a well designed extension typically adds more value than it costs while giving you the home you actually want. For many Auburn homeowners, adding a proper living area, extra bedrooms or a second bathroom makes far more sense than selling and starting again somewhere else.

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!"

From drawings to completion it was a breeze working with them. They were easy to work with and extremely efficient and professional. Thank you for all the hard work and effort, I will recommend you to everyone I know."

There are some exemptions for very minor works, but anything substantial needs approval. Our team manages the entire approval process for you, from preparing plans through to lodgement and liaising with council.
Can you match the brick on older Auburn homes?
Yes, we regularly work with the older brick homes common throughout Auburn and take care to match existing brickwork as closely as possible.
