Home Extensions Oxley Park
Built For The Way You Live
Oxley Park features mostly brick homes built from the late 1990s through to the mid 2000s, sitting on modest blocks typically between 450 and 600 square metres. These family homes were built during an era when developers prioritised quantity over space, leaving many with cramped living areas and limited storage. An extension makes perfect sense when you need more room but want to stay in a suburb with good schools and transport links.
We’ve completed extensions throughout Oxley Park and neighbouring suburbs like St Marys and Plumpton, working with families who’ve outgrown their original floor plans. Our team knows the local housing stock well and understands what works on these blocks. Whether it’s opening up the back of the house or adding a second storey, we deliver practical solutions that suit how families actually live.
Oxley Park sits in a practical location with decent access to the M4 and local schools, making it a suburb where families want to stay long term. Property values have climbed steadily as Western Sydney continues to grow, and a well planned extension adds serious value to your home. Instead of selling up and dealing with stamp duty and moving costs, extending your existing home often makes better 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."

"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!"

How long does a home extension take in Oxley Park?

Do I need council approval for a home extension in Oxley Park?
Most extensions in Oxley Park require either a Development Application or Complying Development Certificate from Penrith Council. Some smaller additions may qualify for exempt development, but this depends on your specific plans and property. We manage the entire approval process for you, working with certifiers and council to get your extension approved.
Can I add a second storey to my Oxley Park home?
Yes, most homes in Oxley Park are single storey brick construction from the late 1990s and 2000s, which are generally suitable for a second storey addition. We’ll conduct a structural assessment to confirm your existing foundations and frame can support the additional load. A second storey is often the best option on smaller Oxley Park blocks where you want more space without losing backyard area.
