Home Extensions Inner West
Built For The Way You Live
The Inner West is filled with Federation and Victorian era homes on smaller blocks, typically 350 to 550 square metres. Most of these houses were built between 1890 and 1930 with compact floor plans that don’t suit modern family living. An extension is often the smartest way to get the space you need without leaving the area.
We’ve completed extension projects right across the Inner West, from Marrickville and Newtown to Leichhardt, Dulwich Hill, Stanmore, and Petersham. Our team understands the character of these older homes and knows how to add space while respecting the original architecture. Whether it’s a rear extension for an open plan kitchen and living area or a second storey addition, we’ve done it all across the Inner West.
Property prices in the Inner West continue to climb, making it harder to upsize by buying a bigger home. Adding an extension costs significantly less than selling and moving, plus you keep the location and community connections you value. A well designed extension can add $200,000 or more to your property value while giving you the extra bedrooms, living space, or home office you actually need.

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 Inner West?
Most home extensions take between 3 to 6 months from DA approval through to final handover. The timeline depends on the scope of work, weather conditions, and any unforeseen issues with older homes. We’ll give you a realistic timeframe during the quoting process and keep you updated throughout construction.
Do I need council approval for a home extension in Inner West?
Most extensions require either a Development Application or Complying Development Certificate in New South Wales. The Inner West Council has specific planning controls for heritage conservation areas that affect many properties. We manage the full approval process including architectural plans, engineering, and council submissions so you don’t have to worry about it.
Can you match the period features of my Federation home?
Absolutely. We work with Federation, Victorian, and early Californian bungalow homes every day across the Inner West. Our team knows how to source or replicate period details like timber fretwork, corbels, and decorative features so your extension looks like it’s always been part of the house. We can also design contemporary additions that complement rather than copy the original home if that’s your preference.
Do you service all areas of Inner West?
Yes we service all suburbs across Inner West. Call 1300 098 730 to discuss your project.
