Home Extensions Sutherland Shire
Built For The Way You Live
Most homes across Sutherland Shire were built between the 1960s and 1980s on decent sized blocks, particularly through Caringbah, Miranda, and Gymea. These original three bedroom brick homes sit on 550 to 700 square metre blocks, giving you real options to extend rather than move. The bones are solid but the layouts don’t work for how families live today.
We’ve completed extensions right across the Shire, from Cronulla beachside properties to family homes in Sylvania Waters, Kirrawee, and Menai. Whether you’re in Sutherland, Engadine, or anywhere between, we understand the local building conditions and council requirements. Our team knows these streets and the homes on them.
Property prices in Sutherland Shire have climbed steadily, making it expensive to upsize into a bigger home once you factor in stamp duty and moving costs. Adding a quality extension gives you the extra space you need while keeping you in the area you love, close to schools, the beaches, and your community. A well designed extension typically adds more value than it costs to build.

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 Sutherland Shire?

How long does a home extension take in Sutherland Shire?
Most home extensions take between 3 to 6 months from council approval through to final handover. The timeframe depends on the scope of work, weather conditions, and any site specific challenges. We’ll give you a realistic timeline during the quoting process and keep you updated throughout the build.
Do I need council approval for a home extension in Sutherland Shire?
Most extensions require either a Development Application or Complying Development Certificate from Sutherland Shire Council. Some minor additions may qualify for exempt development but this is rare. We manage the entire approval process including plans, submissions, and any follow up requirements so you don’t need to worry about the paperwork.
Can you extend homes on sloping Sutherland Shire blocks?
Absolutely. Many homes in suburbs like Jannali, Como, and parts of Menai sit on sloping blocks which creates opportunities for clever multi level extensions. We work with the natural fall of your land to create functional spaces without excessive excavation costs. Sloping sites often allow for great under house storage or rumpus areas.
Do you service all areas of Sutherland Shire?
Yes we service all suburbs across Sutherland Shire. Call 1300 098 730 to discuss your project.
