Home Extensions Chester Hill
Built For The Way You Live
Chester Hill is dominated by post war fibro and brick homes built through the 1950s and 60s, typically sitting on 550 to 650 square metre blocks. Many of these homes feature original layouts with small kitchens, single bathrooms and limited living space that no longer suit modern family life. An extension makes far more sense than buying in today’s market, especially when the bones of these homes are solid and the blocks offer plenty of room to build.
We’ve completed dozens of extensions across Chester Hill and neighbouring suburbs like Sefton, Bass Hill and Yagoona, working with the typical housing stock in this area. Our team understands how to work with older homes, managing asbestos removal when needed and matching new additions to existing construction methods. Every project is handled by our licensed builders from concept right through to completion.
Chester Hill remains one of the more affordable suburbs in the Canterbury Bankstown area, which means homeowners here can invest in their property without the massive mortgage that comes with moving. Families are choosing to stay put and extend rather than uproot to find more space. A well planned extension can add $150,000 to $200,000 in value while giving you the home layout your family actually needs.

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."

Do I need council approval for a home extension in Chester Hill?
Most extensions in Chester Hill require either Development Approval or Complying Development approval through Canterbury Bankstown Council. Some smaller additions may qualify for exempt development, but this is rare for liveable extensions. Our team manages the entire approval process including all documentation, plans and council liaison.
Can you extend older fibro homes in Chester Hill?
Absolutely. We work with older fibro and brick homes across Chester Hill all the time. Many of these post war homes contain asbestos materials, which we manage safely with licensed removalists before starting any extension work. The existing structure is assessed and we build new additions that integrate properly with the original home.
