Home Extensions Bidwill
Built For The Way You Live
Bidwill homes were mainly built through the 1960s and 1970s as part of the Department of Housing developments, with typical brick homes on modest 550 to 650 square metre blocks. Many of these three bedroom homes now have families who’ve outgrown the original layout, making an extension the smartest way to add space without leaving the area. The compact floor plans and basic designs from that era mean there’s plenty of opportunity to extend out the back or add a second level.
We’ve completed dozens of extensions throughout Bidwill and neighbouring Mount Druitt, Emerton and Dharruk, working with families who need extra bedrooms, bigger living areas or modern kitchens. Our team knows these homes inside out, from the original brick construction to the typical plumbing layouts and what works best on these blocks. Whether you’re adding a single bedroom or doing a full rear extension with open plan living, we handle the design, approvals and build from start to finish.
Bidwill has become popular with young families looking for affordable homes close to schools and transport, with many properties now privately owned after being purchased from Housing NSW. Rather than selling and moving, more homeowners are choosing to extend and renovate, especially given the current property prices across Western Sydney. A well planned extension can easily add $100,000 or more in value while giving your family the space you actually need.

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!"
