Home Extensions Leichhardt
Built For The Way You Live
Leichhardt is filled with Federation, Victorian and Edwardian terraces and workers cottages, most on tight 200 to 300 square metre blocks. Many homes still have their original two bedroom layouts with narrow hallways and small back additions from the 70s and 80s. An extension is often the smartest way to gain the extra bedroom, bathroom or open plan living space your family needs without leaving the area.
We’ve completed dozens of extensions throughout Leichhardt and nearby suburbs like Annandale and Lilyfield. Our team knows how to work with the constraints of narrow terraces and older foundations, and we understand the local character requirements that come with building in a heritage sensitive area. Every project is managed by licensed builders who live and work across the Inner West.
Leichhardt families love the Italian Club, weekend markets at Norton Street and easy access to the city, but many older homes just don’t suit modern family life. Properties here hold their value well, and a properly designed extension typically returns more than it costs when you compare sale prices of renovated versus unrenovated homes. Adding a second storey or pushing out the back can turn a cramped two bedroom cottage into a comfortable family home worth holding onto for years.

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."

FAQS
Got a question?
How much does a home extension cost in Leichhardt?

Second storey additions generally start from $250,000. We provide a free quote after assessing your property and understanding what you need from the space.
How long does a home extension take in Leichhardt?
Most extensions take between 3 to 6 months from council approval through to final handover, depending on the scope of work. A single room addition might be done in 3 months, while a full two storey extension could take closer to 6 months. We provide a detailed timeline during the quoting process so you know exactly what to expect.
Do I need council approval for a home extension in Leichhardt?
Most extensions in Leichhardt require either a Development Application or Complying Development Certificate through the Inner West Council. Some smaller additions may qualify as exempt development, but this is less common given the heritage considerations across much of the suburb. Our team manages the full approval process including plans, submissions and any follow up requirements.
Can you extend a narrow terrace in Leichhardt?
Absolutely. We’ve extended dozens of narrow terraces throughout Leichhardt and know how to maximise space on tight blocks. The key is clever design that works with your existing floor plan, whether that’s pushing out the back, adding a second storey or reconfiguring the internal layout. Most terraces can accommodate a modern extension without compromising the street character or neighbouring properties.
