Home Extensions St Helens Park
Built For The Way You Live
St Helens Park homes are predominantly newer construction from the 1990s and 2000s, built on reasonably sized blocks but often with smaller original footprints. Many of these properties were designed with basic layouts that no longer suit growing families or modern living requirements. An extension makes perfect sense when you’ve got the land but need more functional space.
We’ve completed numerous extensions throughout St Helens Park and across to Gregory Hills and Ingleburn, working with the local housing styles and council requirements. Our team knows the area well and understands what works for these properties. From second storeys to rear ground floor additions, we design extensions that feel like they’ve always been part of the home.
St Helens Park continues to attract families looking for affordable housing with good access to schools and the M5. Rather than selling and moving when you outgrow your home, a well planned extension lets you stay in the community while adding substantial value to your property. The local market responds well to homes with quality additions that provide extra bedrooms, living space or modern kitchens.

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 St Helens Park?
Most extensions take between 3 to 6 months from council approval through to final handover. The timeline depends on the scope of work, weather conditions and any site specific considerations. We provide a realistic schedule during the quoting process and keep you informed throughout construction.
Do I need council approval for a home extension in St Helens Park?
Most home extensions require either a Development Application or Complying Development Certificate from Camden Council. The approval pathway depends on your extension size, setbacks and local planning rules. We manage the full approval process including plans, documentation and council liaison so you don’t have to navigate it alone.
Can I add a second storey to my St Helens Park home?
Yes, many St Helens Park homes are suitable for second storey additions given the relatively flat terrain and solid foundations on newer builds. We assess your existing structure to confirm it can support the additional load. A second storey is often the most cost effective way to gain space without losing backyard area.
