Home Extensions Chiswick
Built For The Way You Live

Chiswick is home to mostly post war brick homes and Federation cottages on smaller blocks, many between 400 and 600 square metres. These older homes were built with different family needs in mind, and many lack the open living spaces and master suites that modern families need. An extension lets you stay in the area you love without the upheaval and expense of moving.

We’ve completed dozens of extensions in Chiswick and neighbouring suburbs like Abbotsford and Russell Lea. Our team knows the local housing stock well, from the brick and tile homes that line the residential streets to the older cottages closer to the water. We work with the character of your home while adding the space and functionality you need.

Chiswick offers great schools, riverside parks and easy access to the city, which is why families want to stay here long term. The property market reflects this, with homes in high demand and limited supply. A well designed extension can add significant value while giving you the home that actually works for your family, without leaving the suburb.

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!"

FAQS

Got a question?

How much does a home extension cost in Chiswick?

A single room addition typically starts from around $80,000, while a full ground floor extension usually begins from $150,000. Second storey additions generally start from $250,000 depending on size and finishes. We provide a free quote after assessing your home and discussing what you need.

How long does a home extension take in Chiswick?

Most home extensions take between three to six months from council approval through to final handover. The timeline depends on the scope of work, weather conditions and any site specific factors. We’ll give you a realistic timeframe once we’ve assessed your property and finalised the design.

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

Most extensions in Chiswick require either a Development Application or Complying Development Certificate from Canada Bay Council. Some smaller additions may qualify for exempt development, but this depends on your specific property and what you’re planning. Our team manages the full approval process for you, from preparing plans through to lodgement and follow up.

Can you extend a small block in Chiswick?

Yes, we regularly work with the smaller blocks common throughout Chiswick. Many homes here sit on 400 to 500 square metre blocks, which still offer good extension potential when designed properly. We look at your setbacks, site coverage limits and how to maximise usable space without overcapitalising.

Do you service Chiswick and surrounding suburbs?

Yes we service Chiswick and all surrounding suburbs. Call 1300 098 730 to discuss your project.
