Home Extensions Banksia
Built For The Way You Live
Banksia’s housing stock is mostly original brick homes from the 1950s and 1960s, built on relatively small blocks that made sense back then but don’t suit modern family life. Most homes sit on 450 to 600 square metre blocks with good side access and potential to extend rearward. An extension is often the smartest way to get the space you need without leaving a well located, affordable suburb close to the airport and beaches.
We’ve completed plenty of extensions throughout Banksia and nearby Rockdale, Brighton-Le-Sands and Kyeemagh over the years. Our team knows the local council requirements and what works with the typical brick and tile homes common throughout the area. Most projects involve opening up the rear of the home, adding a second living area, and creating better connection to the backyard.
Banksia offers genuine value compared to other parts of the St George area, with families moving here for proximity to schools, shops on Lady Robinson Beach and reasonable property prices. A well designed extension can add $150,000 to $250,000 in property value while giving your family the space to grow. With Banksia’s location near Botany Bay and transport links, it makes more sense to extend than uproot and move further out.

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."

Absolutely, we work with original 1950s and 1960s brick homes all the time throughout Banksia.
