Home Extensions South Penrith
Built For The Way You Live
South Penrith homes are mainly brick veneer and weatherboard builds from the 1970s and 1980s, sitting on decent sized blocks between 550 and 700 square metres. These older layouts have smaller living areas and separate kitchens that don’t work for how families live today. An extension lets you stay in a suburb with good schools and transport while getting the space you actually need.
We’ve completed plenty of extensions throughout South Penrith and across to Werrington, Kingswood and Cambridge Park. Most projects involve opening up the back of the house to create open plan living that flows to the yard, plus adding extra bedrooms or a second bathroom. Our team knows the local council requirements and typical site conditions, which keeps your project moving without surprises.
South Penrith offers affordability and accessibility that’s hard to beat, with the train station and M4 making commutes manageable. Property prices here are still reasonable compared to inner suburbs, which means a well designed extension gives you real value for money. Adding 50 to 80 square metres of quality living space can completely change how your home works without the massive expense and stress of buying elsewhere.

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!"

Do I need council approval for a home extension in South Penrith?

Our team manages the full approval process including plans, surveys and submissions so you don’t have to deal with the paperwork.
Can you extend older brick homes in South Penrith?
Absolutely, we extend plenty of the older brick and weatherboard homes that dominate South Penrith.
