Home Extensions Dundas
Built For The Way You Live
Dundas is dominated by solid brick homes from the 1960s and 70s, sitting on good sized blocks that give you room to extend. Most homes have generous backyards and original three bedroom layouts that no longer work for modern families. An extension makes far more sense than moving when you’ve got the land and location already sorted.
We’ve completed plenty of extensions across Dundas and nearby areas like Telopea and Carlingford, turning cramped three bedroom homes into comfortable family spaces. Our team knows the local housing stock inside out, from the post war fibro cottages near Marsden Road through to the newer brick homes closer to Dundas Valley. Whether it’s opening up the back of the house or adding a second level, we design extensions that match the original home and suit how local families actually live.
Dundas sits in a convenient pocket between Parramatta and the upper North Shore, with families staying put rather than upsizing elsewhere. The local schools and easy access to Epping and the city keep people here long term. A well planned extension protects your investment and gives you the space you need without the hassle and cost of selling in a competitive market.

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 Dundas?
A single room addition typically starts from $80,000, while a full ground floor extension begins around $150,000. Second storey additions start from $250,000 depending on size and finishes. We provide a free detailed quote after assessing your home and understanding exactly what you need.
How long does a home extension take in Dundas?
Most extensions take between 3 to 6 months from DA approval through to final handover, depending on the size and complexity of the build. The approval process with Parramatta Council typically adds another 8 to 12 weeks beforehand. We’ll give you a realistic timeline upfront and keep you updated throughout the entire process.
Do I need council approval for a home extension in Dundas?
Most extensions in Dundas require either a Development Application or Complying Development Certificate through Parramatta Council. Some smaller additions may qualify for exempt development but it depends on your specific site and proposal. We manage the full approval process for you, from plans through to certification.
Can you extend older brick homes in Dundas?
Absolutely. The 60s and 70s brick homes common throughout Dundas are perfect candidates for extensions. We regularly work with these homes, matching brickwork and ensuring the new addition integrates properly with the existing structure. The solid construction and good block sizes make extending straightforward compared to newer developments on smaller lots.
