Home Extensions Redfern
Built For The Way You Live
Redfern’s housing mix includes Victorian terraces, workers cottages and Federation homes on compact blocks, many between 150 and 250 square metres. With limited land available and rising property prices, extending your existing home delivers far better value than buying a larger property. Most homes in the area were built between 1880 and 1930, making them ideal candidates for carefully planned rear or second storey additions.
We’ve completed dozens of extensions throughout Redfern and neighbouring suburbs like Waterloo and Darlington, working with the typical constraints of narrow terraces and tight sites. Our team knows how to maximise space without losing the character that makes these homes special. Every project is tailored to the specific home, whether it’s a single storey rear extension or a full second level addition.
Redfern’s proximity to the CBD and universities makes it highly desirable, with property values reflecting that demand. Adding a well designed extension can increase your home’s value by $200,000 to $400,000 while giving your family the extra space you need. For growing families or those working from home, an extension is often the smartest financial decision compared to moving suburbs.

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."

We manage the entire approval process for you, including plans, documentation and council liaison.
