Home Extensions St Peters
Built For The Way You Live

St Peters is dominated by brick Federation and Californian bungalows along with some weatherboard cottages, most sitting on compact blocks between 250 and 400 square metres. These solid older homes were built for different times, and families today need more living space, better connection to backyards, and modern kitchens that actually work for daily life. A well designed extension makes far more sense than buying up in this tightly held suburb where good properties rarely come to market.

We’ve completed dozens of extensions throughout St Peters and the surrounding Inner West, from single storey rear additions on Federation homes to full second storey builds that double the living space. Every project starts with understanding how your family actually lives, then designing an extension that works with your existing home’s footprint and character. Our team knows the local housing stock inside out and what Inner West Council looks for in extension applications.

St Peters sits close to the airport, the CBD and both Newtown and Marrickville’s cafes and shops, making it popular with young families who refuse to compromise on location. Property values here have climbed steadily, and a quality extension typically returns more than the build cost while letting you stay in a suburb you’ve already settled into. Adding 40 to 60 square metres of well planned living space transforms how a period home functions without the upheaval and cost of moving.

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!"

Our team manages the full approval process including architectural plans, engineering and all council submissions.

Can you extend a Federation bungalow in St Peters?

Absolutely, we extend Federation and Californian bungalows in St Peters regularly.
