Home Extensions Bangor
Built For The Way You Live
Bangor’s housing stock is predominantly brick veneer and fibro homes built from the 1970s and 1980s, sitting on generous quarter acre to half acre blocks. These original homes typically feature three bedrooms and a single bathroom, which no longer suits modern family living. With large blocks and established gardens, extending makes far more sense than moving, especially given the area’s proximity to Woronora River and quality schools.
We’ve completed dozens of extensions throughout Bangor and neighbouring Menai, Barden Ridge and Woronora Heights. Most projects involve adding a second storey, extending the back of the home for an open plan living area, or converting garages into additional bedrooms. Our team knows the local building requirements and works with the natural slope of many Bangor properties to maximise space and views.
Bangor families stay put because of the tight knit community, local schools and bushland surrounds. Property values have climbed steadily, making renovation a smart investment compared to buying elsewhere in the Shire. A well planned extension typically adds $200,000 to $400,000 in value while giving you the home layout your family actually needs without leaving the neighbourhood you love.

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 Bangor?
A single room addition in Bangor typically starts from $80,000, while a full ground floor extension with kitchen and living areas starts from $150,000. Second storey additions generally begin around $250,000 depending on size and finishes. We provide a free detailed quote after assessing your property and discussing your specific needs.
How long does a home extension take in Bangor?
Most home extensions in Bangor take between 3 to 6 months from council approval through to final handover. Smaller single room additions may be completed in 10 to 12 weeks, while larger two storey projects can take 6 to 9 months. Timeline depends on design complexity, weather and material availability.
Do I need council approval for a home extension in Bangor?
Most extensions in Bangor require either a Development Application or Complying Development Certificate from Sutherland Shire Council. Some smaller additions under 20 square metres may qualify as exempt development, but this is rare for liveable extensions. Our team manages the entire approval process including all plans, engineering and submissions to council.
Can you extend on a sloping block in Bangor?
Absolutely. Many Bangor properties sit on sloping blocks, which we factor into the design and foundation work. Sloping sites often provide opportunities for under house storage or additional living space. We’ve completed numerous extensions on sloped blocks throughout Bangor and the engineering is all part of our service.
Do you service Bangor and surrounding suburbs?
