Home Extensions Jamisontown
Built For The Way You Live
Jamisontown homes are mostly brick veneer and weatherboard builds from the 1980s and 1990s, sitting on decent blocks that give you room to extend. Many properties here feature three bedroom layouts that worked well when the kids were young but need extra space as families grow. An extension makes far more sense than selling and moving, especially when you’ve got established gardens and good neighbours.
We’ve completed extensions throughout Jamisontown and neighbouring areas like Caddens and Erskine Park, working with the typical housing stock in this part of Penrith. Our team knows how to add a fourth bedroom and ensuite, extend the living areas out the back, or create that second storey without compromising the character of your home. Every project gets the same attention whether it’s a single room addition or a full ground floor renovation.
Jamisontown offers affordable family living close to Penrith CBD and the M4, which is why many homeowners choose to extend rather than upgrade. The local market rewards well executed extensions, particularly those that add a second living space or extra bedroom. You’re investing in your property while avoiding the stress and cost of moving, which matters when you’re already settled in a good street.

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."

Our team manages the full approval process for you, working with our certifiers and planners to get everything sorted.
Can I add a second storey to my Jamisontown home?
Most single storey homes in Jamisontown are suitable for a second storey addition, though we need to check your existing foundations and frame first.
