Home Extensions Bonnyrigg
Built For The Way You Live
Bonnyrigg is dominated by brick homes from the 1970s and 1980s, with typical block sizes ranging from 550 to 700 square metres. Many of these properties were built with basic three bedroom layouts that no longer suit modern family living. Rather than moving, extending your current home makes financial sense and lets you stay in an area close to schools, parks and established community connections.
We’ve completed dozens of extensions across Bonnyrigg and nearby suburbs like Bonnyrigg Heights and Edensor Park, working with families who need more space without leaving the area. Our projects range from single room additions and ground floor living extensions through to full second storey builds on these solid brick homes. We know the local housing stock well and design extensions that complement the existing architecture while adding real value.
Bonnyrigg attracts young families and long term residents who value the affordability and accessibility to Fairfield, Wetherill Park and the M7. Adding a well designed extension can increase your property value by 15 to 25 percent while giving you the extra bedrooms, living space or outdoor entertaining area your family actually needs. With median house prices still reasonable compared to inner west suburbs, investing in your current home through an extension makes solid financial sense.

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."
Amanda
"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!"
Angela
"Fantastic! Monstructions did an amazing job on my home extension, all the boys that worked on my house were professional and polite, and their quality of work was second to none. 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."

How long does a home extension take in Bonnyrigg?

Do I need council approval for a home extension in Bonnyrigg?
Most extensions in Bonnyrigg require either a Development Application or Complying Development Certificate through Canterbury Bankstown Council. Some minor additions may fall under exempt development, but it’s rare for liveable extensions. We manage the full approval process for you, working with certifiers and council to get your project approved efficiently.
Can I add a second storey to my Bonnyrigg brick home?
Yes, most brick homes built in Bonnyrigg during the 1970s and 1980s have adequate foundations for a second storey addition. We conduct a structural assessment to confirm the existing footings can support the additional load. Many homeowners choose this option to maximise their land without losing backyard space.
