Home Extensions Greenfield Park
Built For The Way You Live
Greenfield Park features mostly brick homes built from the 1970s through to the 1990s, sitting on generous blocks that typically range from 550 to 700 square metres. Many of these homes were built with basic three or four bedroom layouts that no longer suit how families live today. With solid bones and good sized yards, these properties are perfect candidates for extensions rather than the cost and upheaval of moving.
We’ve completed dozens of extensions across Greenfield Park and neighbouring suburbs like Fairfield Heights and Smithfield, working with the typical housing stock in this area. Our team knows how to work with the brick construction common to homes here and how to design additions that complement the existing architecture. From single storey rear extensions to complete second storey additions, we handle projects of all sizes across the local area.
Greenfield Park offers affordable family living with good access to schools, Fairfield CBD and the M7, making it popular with young families needing more space. Property values here have climbed steadily, and a well designed extension typically adds more value than it costs while giving you the home you actually need. Rather than buying a bigger house in a less convenient location, extending your current home lets you stay in the community where you’re already established.

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 Greenfield Park?
A single room addition typically starts from $80,000, while a full ground floor extension starts from $150,000 depending on finishes and complexity. Second storey additions generally start from $250,000 including structural work and new stairs. We provide a free, detailed quote based on your specific home and requirements.
How long does a home extension take in Greenfield Park?
Most extensions take between 3 to 6 months from council approval through to final handover, depending on the size and complexity of your project. The council approval process itself typically adds another 8 to 12 weeks before construction starts. We’ll give you a clear timeline during the quoting process so you know exactly what to expect.
Do I need council approval for a home extension in Greenfield Park?
Most extensions in Greenfield Park require either a Development Application or Complying Development Certificate from Canterbury Bankstown Council. Some very minor additions may qualify for exempt development, but this is rare for meaningful extensions. Our team manages the entire approval process on your behalf, working with our architects and certifiers to get your project approved.
Can you add a second storey to brick homes?
Yes, most brick homes in Greenfield Park can support a second storey addition with proper structural assessment and engineering. We arrange a structural inspection early in the design process to determine what reinforcement is needed. Many homes from the 70s, 80s and 90s have adequate foundations that make second storey additions very achievable.
