Home Extensions Allawah
Built For The Way You Live
Allawah is dominated by Federation and interwar homes on decent blocks of 450 to 600 square metres, with many original cottages and bungalows still in family hands. These older homes typically have two or three bedrooms, a single bathroom and limited living space. With good bones and solid construction, these properties are ideal candidates for extensions rather than knockdown rebuilds.
We’ve completed dozens of extensions across Allawah and nearby suburbs like Hurstville and Carlton, adding second storeys, rear living extensions and additional bedrooms. Most of our work involves opening up the back of these older homes to create proper family living areas with connection to the backyard. Our team knows the local housing stock inside out and can advise on what works best for your block and budget.
Allawah sits in a quiet pocket close to Hurstville CBD, with families attracted to the local schools and train access to the city. Extending your existing home makes financial sense when you consider stamp duty, moving costs and the premium you’d pay for a bigger home in the same area. A well designed extension can add $200,000 to $400,000 in value while giving you the extra space your family needs right now.

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."
