Home Extensions Hazelbrook
Built For The Way You Live
Hazelbrook homes are mostly post war fibro and weatherboard cottages from the 1950s and 60s, sitting on generous bushland blocks that often back onto national park. These older mountain homes typically have small living areas, compact kitchens and limited bathroom space that no longer works for modern family life. The large block sizes mean there’s plenty of room to extend without losing valuable backyard space.
We’ve completed extensions across Hazelbrook and neighbouring suburbs like Lawson and Woodford, working with the unique challenges of mountain construction including steep sites and bushfire requirements. Our team understands local council requirements and how to design extensions that complement the relaxed mountain character of existing homes. Every project is managed by licensed builders who live and work in the Blue Mountains region.
Hazelbrook attracts families and tree changers looking for affordable mountain living within commuting distance of Penrith and Western Sydney. The property market here rewards well designed extensions, especially when they add a second living area or extra bedroom while respecting the natural bushland setting. Rather than upsizing to a larger home and losing that established mountain garden, most homeowners find extending their current property makes better financial 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."
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."

How long does a home extension take in Hazelbrook?

Smaller single room additions can sometimes be completed faster, while larger two storey extensions may take longer. We provide a clear timeline during the quoting process so you know exactly what to expect.
Do I need council approval for a home extension in Hazelbrook?
Most extensions in Hazelbrook require either a Development Application or Complying Development Certificate from Blue Mountains City Council. Bushfire requirements and heritage considerations can affect the approval process in some parts of Hazelbrook. Our team manages the full council approval process including all documentation, engineering reports and liaising with certifiers.
Can you extend homes on steep or bushland blocks?
Absolutely. We regularly work on steep and heavily treed blocks throughout Hazelbrook and have extensive experience with the engineering and bushfire requirements these sites demand. Many Hazelbrook properties back onto national park or have significant slope, and we design extensions that work with the natural landscape rather than against it.

Yes we service Hazelbrook and all surrounding suburbs. Call 1300 098 730 to discuss your project.
