Home Extensions Prestons
Built For The Way You Live
Prestons features a mix of older fibro cottages from the 1970s and 80s alongside newer brick homes built in the last 20 years, most sitting on quarter acre blocks or larger. Many families who bought here years ago now find themselves needing more space as kids grow or parents move in. Rather than selling up and leaving the area, an extension lets you stay put and create the home you actually need.
We’ve completed extensions throughout Prestons and neighbouring areas like Edmondson Park and Leppington, working with the typical housing stock you see around here. Whether it’s adding a second storey to an older single level home or extending out the back to create an open plan living area, we understand what works on these blocks. Our team knows the local council requirements and what Liverpool City Council expects in terms of setbacks and approvals.
Prestons has changed a lot over the past decade with new developments bringing young families to the area while established residents are choosing to stay and renovate. Property values have climbed steadily, and a well planned extension can add serious equity to your home while giving you the extra bedrooms, living space or granny flat you need. It’s often smarter financially than buying elsewhere, especially when you factor in stamp duty and moving costs.

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!"

FAQS
Got a question?
How much does a home extension cost in Prestons?
A single room addition typically starts from around $80,000, while a full ground floor extension starts from $150,000 depending on size and finishes. Second storey additions generally start from $250,000. We provide a free quote after assessing your property and understanding exactly what you need.
How long does a home extension take in Prestons?
Most extensions take between 3 to 6 months from DA approval through to final handover, depending on the scope of work. The council approval process with Liverpool City Council typically adds another 8 to 12 weeks before we can start building. We’ll give you a clear timeline once we understand your project.
Do I need council approval for a home extension in Prestons?
Most extensions in Prestons require either Development Approval or a Complying Development Certificate from Liverpool City Council. Some smaller additions might qualify as exempt development, but that’s rare for anything meaningful. We manage the full approval process including all drawings, documentation and council liaison so you don’t have to worry about it.
Can I extend an older fibro home in Prestons?
Absolutely, we’ve extended plenty of older fibro homes throughout Prestons and the results can be fantastic. The key is getting the structural engineering right and making sure the old and new sections tie together properly. Many homeowners choose to update the existing house at the same time to create a cohesive look throughout.
