Home Extensions Birchgrove
Built For The Way You Live
Birchgrove is filled with Victorian and Federation homes on tight blocks, many between 200 and 300 square metres. These period homes typically have two or three small bedrooms and limited living space, making them perfect candidates for a well planned extension. With heritage controls across much of the peninsula, getting the design right matters even more here.
We’ve completed extensions throughout Birchgrove and across the peninsula, working with the constraints these older homes present. Our team knows how to match existing rooflines, brickwork and detailing while creating modern, functional spaces inside. Whether it’s pushing out the back, adding a second storey or reconfiguring the entire ground floor, we handle the full process from concept to completion.
Property values in Birchgrove remain strong, with families wanting to stay in the area rather than move further out. A quality extension lets you keep your location and lifestyle while getting the space your family needs. The return on investment is solid here, especially when the work is done properly and suits the character of your home.

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."

How long does a home extension take in Birchgrove?
Most home extensions in Birchgrove take between 3 to 6 months from council approval through to final handover. The timeline depends on the size and complexity of your project, as well as any site access constraints common on the peninsula. We provide a clear schedule during the quoting process so you know exactly what to expect.
Do I need council approval for a home extension in Birchgrove?
Yes, most extensions in Birchgrove require either Development Application or Complying Development Certificate approval from Inner West Council. Heritage controls apply to many properties in the area, which can affect the approval process. Our team manages the full application process including drawings, documentation and council liaison.
Can I extend a Federation home in Birchgrove?
Absolutely. Federation homes are ideal for extensions when the design respects the existing character and follows heritage guidelines. We’ve worked on many period homes throughout Birchgrove, matching materials and details while creating modern living spaces. The key is getting the design right from the start, which is where our experience with Inner West heritage properties matters.
