Home Extensions Narellan Vale
Built For The Way You Live

Narellan Vale’s housing stock is predominantly modern, with most homes built from the late 1990s onwards on medium to large blocks ranging from 450sqm to 700sqm. Many of these homes were built with standard three or four bedroom layouts that made sense for young families at the time, but as kids grow and working from home becomes standard, homeowners are finding they need more space. An extension makes far more sense than selling and moving, especially when your block has the room and your street has everything you need.

We’ve completed numerous extensions throughout Narellan Vale and surrounding suburbs like Harrington Park and Camden, working with the area’s brick and render homes to add second storeys, extend living areas, and create proper home office spaces. Our team knows the local building landscape well, from soil conditions to council requirements, which means fewer surprises and smoother approvals. Whether you’re adding a ground floor extension or going up with a second storey, we make sure the new work matches your existing home perfectly.

Narellan Vale continues to attract families who want good schools, parks, and reasonable proximity to both Camden and the newer Macarthur developments. Property values have climbed steadily, and a well designed extension can add significant value while giving you the home you actually need. Rather than competing in an expensive market for a bigger house, extending your current home lets you stay in the area you know with less stress and better return on investment.

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 Narellan Vale?

Most extensions in Narellan Vale require either Development Approval or a Complying Development Certificate from Camden Council. The approval pathway depends on your extension size, setbacks, and what’s allowed under local planning rules. We manage the full approval process for you, including all documentation and council liaison.

Can I add a second storey to my Narellan Vale home?

Yes, most Narellan Vale homes are suitable for a second storey addition, especially the brick homes built from the late 90s onwards which generally have adequate footings. We’ll assess your existing structure first and let you know if any strengthening work is needed. A second storey is often the best way to maximise space without losing your backyard.
