Home Extensions Wentworthville
Built For The Way You Live
Wentworthville is packed with solid brick homes from the 1960s through to the 1990s, mostly sitting on 550 to 700 square metre blocks. These houses were built for smaller families and many now feel cramped, with tight living areas and limited storage. An extension makes far more sense than moving, especially when you’ve got established gardens and you’re close to Wentworthville station and local schools.
We’ve completed dozens of extensions throughout Wentworthville and neighbouring suburbs like Westmead and Pendle Hill, working with the typical brick and tile homes that fill these streets. Most projects involve opening up the back of the house to create modern open plan living, adding a second storey for extra bedrooms, or building out to the side for a bigger kitchen and dining space. Our team knows how to work with these older homes and their foundations.
Wentworthville has become increasingly popular with young families who want to stay close to Parramatta without paying Parramatta prices. Property values have climbed steadily, and a well planned extension can add $150,000 to $250,000 to your home’s value while giving you the space your family actually needs. It’s a smart investment when you consider the cost and hassle of selling and buying elsewhere in the area.

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."

Do I need council approval for a home extension in Wentworthville?
Most extensions in Wentworthville require either a Development Application or Complying Development Certificate from Cumberland Council. Some smaller additions under 20 square metres might qualify as exempt development, but this is rare. Our team manages the full approval process for you, including all plans, documents and council liaising.
Can you extend older brick homes in Wentworthville?
Absolutely, we work with 1960s to 1990s brick homes all the time throughout Wentworthville. The key is properly assessing the existing foundations and structure before we design your extension. Most of these homes are solidly built and perfect candidates for either ground floor or second storey additions with the right engineering and building approach.
