Home Extensions Ashfield
Built For The Way You Live
Ashfield’s housing stock is dominated by Federation and Californian bungalows from the 1910s to 1930s, along with plenty of post war brick homes on blocks that typically run between 450 and 600 square metres. Many of these homes were built with smaller rooms and a single bathroom, which no longer works for modern family life. An extension makes far more sense than moving when you’re sitting on a great block in a well connected suburb with solid infrastructure.
We’ve completed dozens of extensions across Ashfield and nearby suburbs like Croydon and Haberfield, working with the character of older homes while creating modern, functional living spaces. Our team knows how to work with the timber frames and asbestos concerns common in Federation era homes, and we’ve got strong relationships with Inner West certifiers and planners. Whether it’s a rear ground floor extension, a second storey addition or a full renovation with extension, we manage the entire process from concept to completion.
Ashfield sits just 10 kilometres from the CBD with excellent train connections and a strong community feel around the shopping precinct on Liverpool Road. The local property market has remained solid because families want to stay in the area for the schools and transport links. Adding a quality extension not only gives you the space you need now but also protects your investment in a tightly held suburb where good family homes don’t last long on the market.

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 Ashfield?
A single room addition typically starts from around $80,000, while a full ground floor extension usually ranges from $150,000 depending on size and finishes. A second storey addition generally starts from $250,000. We provide a detailed free quote after assessing your home and understanding exactly what you need.
How long does a home extension take in Ashfield?
Most home extensions take between 3 to 6 months from DA approval through to final handover, depending on the scope and complexity of the build. A straightforward single level rear extension sits at the lower end of that timeframe, while a double storey or more complex project takes longer. We provide a clear timeline during the quoting process so you know what to expect.
Do I need council approval for a home extension in Ashfield?
Most home extensions require either Development Approval or a Complying Development Certificate from Inner West Council in NSW. Some very minor additions might fall under exempt development, but this is rare. We manage the full approval process for you, including all architectural drawings, engineering and submissions to council or a private certifier.
Can you extend a Federation home in Ashfield?
Absolutely. We’ve extended many Federation and Californian bungalows across Ashfield and understand how to work with the existing structure respectfully. The key is designing an addition that complements the original home while meeting modern building codes, and we handle everything from asbestos removal to matching original details where it matters.
