Home Extensions Petersham
Built For The Way You Live
Petersham is dominated by Federation and Californian bungalow homes from the early 1900s, sitting on narrow blocks typically around 250 to 350 square metres. Many original homes have small rooms, limited natural light and cramped kitchens that don’t suit modern family life. An extension is often the smartest way to create the open living spaces you need without leaving this well connected suburb.
We’ve completed extensions throughout Petersham and neighbouring suburbs like Stanmore and Lewisham, working with the typical challenges of period homes and compact sites. Our team knows how to match Federation detailing, navigate tight side access and design additions that respect the heritage character while delivering modern functionality. Every project is managed by our licensed builders from concept through to completion.
Petersham offers great schools, local cafes along New Canterbury Road and an easy commute to the city, which keeps property values strong. Renovating and extending is usually more cost effective than buying a larger home in the area, especially with current market prices. A well planned extension can add serious value while giving you the extra space your family actually needs.

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’ll give you a realistic timeframe once we assess your specific property and scope of work.
Do I need council approval for a home extension in Petersham?
Most extensions in Petersham require either a Development Application or Complying Development Certificate from Inner West Council. Heritage overlays in parts of Petersham can add extra requirements. We manage the entire approval process including plans, documentation and council liaison so you don’t have to deal with the paperwork.
Can you match Federation detailing on my Petersham home?
Absolutely. We regularly work with Federation and Californian bungalow homes across Petersham and know how to match original detailing like fretwork, timber posts and rooflines. Our extensions are designed to look like they’ve always been part of the house while giving you modern, open living spaces inside.
