Home Extensions Canterbury
Built For The Way You Live

Canterbury’s housing stock is primarily post-war brick homes and Federation cottages on decent sized blocks, many between 450 and 650 square metres. These homes were built when families were smaller and storage needs were different, making them ideal candidates for a well planned extension. With solid bones and good street appeal, most Canterbury homes benefit more from extending than from knocking down and rebuilding.

We’ve completed dozens of extensions throughout Canterbury and the surrounding suburbs, working with families who need an extra bedroom, a larger living area or a second storey to maximise their block. Our team knows the local housing styles and understands how to design additions that complement the existing home while meeting modern building standards. From single storey rear extensions to complete upper level additions, we’ve seen what works in this area.

Canterbury remains popular with families who want good schools, transport links and an established neighbourhood feel without the Inner West price tag. Property values here continue to climb, and a quality extension typically adds more value than it costs while letting you stay in a location you already know and love. Rather than uprooting your family and paying stamp duty elsewhere, extending your current home often makes the most financial and practical sense.

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 Canterbury?

A single room addition typically starts from $80,000, while a full ground floor extension begins around $150,000. Second storey additions generally start from $250,000 depending on size and finishes. We provide a free, no obligation quote after an on-site assessment of your Canterbury property.

How long does a home extension take in Canterbury?

Most home extensions take between 3 to 6 months from council approval through to final handover, depending on the scope and complexity of your project. The DA approval process with Canterbury-Bankstown Council typically adds another 8 to 12 weeks before construction starts. We’ll give you a clear timeline during your initial consultation.

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

Most extensions in Canterbury require either a Development Application or Complying Development Certificate from Canterbury-Bankstown Council. The type of approval depends on your extension size, setbacks and site constraints. Our team manages the entire approval process including plans, documentation and council liaison so you don’t have to.

Can I add a second storey to my Canterbury home?

Most single storey homes in Canterbury can support a second storey addition, though it depends on your existing foundations and structure. We arrange a structural engineer’s assessment as part of the design process to determine what’s required. Many Canterbury homes have solid brick construction that’s well suited to upper level additions.
