Home Extensions Kurrajong Hills
Built For The Way You Live
Kurrajong Hills features a mix of older brick homes from the 70s and 80s alongside newer rural residential properties on large blocks, often one to five acres. Many of these homes were built with modest footprints that no longer suit modern family needs. Extending makes far more sense than moving, especially when you’ve already got the land and the rural lifestyle you love.
We’ve completed extensions throughout Kurrajong Hills and the surrounding Hawkesbury area, working with the unique challenges of rural properties including bushfire regulations and steep sites. Our team understands the local building requirements and works with council to ensure your project meets all necessary approvals. Whether it’s adding a second living area, extra bedrooms or a modern open plan kitchen, we build extensions that fit your home and your block.
Families move to Kurrajong Hills for the space, the views and the rural feel while staying within reach of Sydney. A well planned extension can add significant value to your property while letting you make the most of your lifestyle block. With property in the area holding strong value, investing in your current home often delivers better returns than selling and buying elsewhere.

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."
