Home Extensions South West Sydney
Built For The Way You Live
South West Sydney homes range from original fibro and brick cottages built in the 60s and 70s through to more recent developments from the 90s and 2000s. Most properties sit on decent sized blocks between 500 and 700 square metres, giving you real options to extend without losing your backyard. An extension makes far more sense than selling up and moving, especially when you’ve already got the land and location sorted.
We’ve completed extensions right across South West Sydney, from Liverpool and Fairfield through to Campbelltown, Camden and Macquarie Fields. Our team knows the local building styles and what works on these blocks, whether you’re adding a second living area, extra bedrooms or going up with a second storey. Every project is managed by our licensed builders who understand the specific council requirements for each South West Sydney LGA.
Families are staying in South West Sydney longer because of the schools, community connections and affordability compared to other parts of Sydney. Property values have climbed steadily over the past decade, making a quality extension a smart investment that gives you the space you need while adding serious value. You get more room for your growing family without the disruption and expense of moving suburbs.

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."

FAQS
Got a question?
How much does a home extension cost in South West Sydney?
A single room addition typically starts from $80,000, while a full ground floor extension with kitchen and living areas starts from $150,000. Second storey additions generally begin from $250,000 depending on size and finishes. We provide a free quote after assessing your property and discussing exactly what you need.
How long does a home extension take in South West Sydney?
Most home extensions take between 3 to 6 months from council approval through to final handover. The timeline depends on the size and complexity of your project, with single room additions at the shorter end and full second storeys taking longer. We give you a detailed schedule before work begins so you know exactly what to expect.
Do I need council approval for a home extension in South West Sydney?
Most extensions require either a Development Application or Complying Development Certificate from your local council in NSW. The requirements vary between Liverpool, Campbelltown, Camden and Fairfield councils, but we manage the full approval process for you. Our team prepares all documentation and liaises with council so you don’t have to navigate the paperwork yourself.
Can I extend a fibro home in South West Sydney?
Absolutely, and we’ve done plenty of extensions on original fibro homes throughout the area. The key is a proper structural assessment to ensure the existing foundations can support the new addition, and sometimes we’ll recommend re-cladding the original house to match. These older homes often sit on great blocks with room to extend, making them perfect candidates for a modern addition.
