Home Extensions Macarthur
Built For The Way You Live
Macarthur homes range from 1970s and 1980s brick family homes on decent sized blocks to newer estates with tighter land. Many properties sit on 600 to 800 square metre blocks, giving you real options to extend outward or add a second level. These solid older homes have good bones but layouts that no longer work for modern family life.
We’ve completed extensions right across Macarthur, Campbelltown and surrounding suburbs, working with the mix of housing styles throughout the area. Whether it’s opening up a cramped kitchen and dining area, adding a master suite, or building a full second storey, we design extensions that suit your home’s existing structure and your family’s needs. Our team knows the local council requirements and works through the approval process efficiently.
Families are choosing to stay in Macarthur rather than move, with good schools, established communities and solid infrastructure keeping people here. Property prices have climbed steadily, making a well planned extension a smart investment compared to selling and buying elsewhere. Adding space to your existing home lets you stay in the area you know while creating the layout your family actually needs.

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!"

How much does a home extension cost in Macarthur?

How long does a home extension take in Macarthur?
Most home extensions take between three to six months from DA approval through to final handover. The timeline depends on the size and complexity of your project, but we keep you informed at every stage. Smaller single room additions can sometimes be completed faster, while second storey builds typically sit at the longer end.
Do I need council approval for a home extension in Macarthur?
Most extensions in Macarthur require either a Development Application or Complying Development Certificate from Campbelltown Council. The approval process depends on your property, the scope of work, and local planning controls. We manage the full approval process for you, including all documentation and council liaison.
Can I extend a 1970s brick home in Macarthar?
Absolutely. Many of the 1970s and 1980s brick homes throughout Macarthur are perfect for extensions, with solid foundations and good bone structure. We assess your existing home first to ensure the structure can support the addition, then design an extension that blends with your home’s existing style. These older homes often have the block size to extend comfortably without overcrowding the site.
