Home Extensions Erskineville
Built For The Way You Live

Erskineville is filled with Victorian and Federation terraces and workers cottages, most sitting on tight blocks around 150 to 200 square metres. These heritage homes offer plenty of character but often lack the space modern families need, making a well planned rear extension the best way to add light, room and functionality. With many properties in conservation areas, you need builders who understand how to work within heritage guidelines while creating spaces that actually work for daily life.

We’ve completed dozens of extensions across Erskineville and neighbouring suburbs like Newtown and St Peters, working on everything from single storey rear additions to full second storey builds. Our team knows the local council requirements inside out and we’ve built strong relationships with certifiers and consultants who specialise in Inner West approvals. Every project is managed by licensed builders who live and work in the area, so we understand exactly what Erskineville homes need.

The Erskineville property market stays strong because of the location, the community feel and proximity to the city. Adding a quality extension can increase your property value by far more than the construction cost, especially when you create additional bedrooms or open plan living that makes the most of your north facing yard. Whether you’re planning to stay long term or position the home for future sale, a professionally built extension delivers real returns.

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!"

Do I need council approval for a home extension in Erskineville?

Most extensions in Erskineville require either a Development Application or Complying Development Certificate through Inner West Council. Many properties sit within conservation areas which adds extra requirements to the approval process. We manage the full application process including all architectural plans, engineering reports and council liaison to get your approval sorted.

Can you extend a terrace house in Erskineville?

Absolutely, terrace extensions are what we do most in Erskineville. The key is maximising your rear yard space while respecting heritage overlays and maintaining access down the side if required.
