Home Extensions Blacktown
Built For The Way You Live

Blacktown has plenty of brick homes from the 1960s through to the 1990s, typically sitting on 550 to 650 square metre blocks. These older homes often have three bedrooms, one bathroom and limited living space, making them perfect candidates for an extension. With good bones and decent block sizes, adding on is usually more practical than moving, especially given how much the area has grown.

We’ve completed extensions right across Blacktown, from Marayong and Rooty Hill through to Seven Hills, Lalor Park and Glenwood. Our team knows the local housing stock well and understands what works for the area. Whether it’s a rear extension for more living space or a second storey to add bedrooms, we design each project to suit the home and the block it sits on.

Blacktown has become increasingly popular with families looking for affordable housing close to the city, schools and transport. Property prices have climbed steadily, making it smart to invest in your existing home rather than chasing the market elsewhere. A well planned extension can add serious value while giving your family the space you need without the stress and cost of moving.

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!"
