Home Extensions Kurrajong
Built For The Way You Live

Kurrajong sits on the ridges overlooking the Hawkesbury Valley, with most homes built between the 1970s and 1990s on generous blocks of 2000 to 5000 square metres. Many original homes feature three bedroom brick or weatherboard designs that haven’t kept pace with how families live today. With land at this size almost impossible to find closer to Sydney, extending your existing home makes far more sense than moving.

We’ve completed extensions throughout Kurrajong and the surrounding ridge communities, working with the sloping blocks and bushfire regulations that define this area. Our team understands the local building requirements and how to design additions that make the most of valley views without overcapitalising. Whether you need an extra bedroom, a proper home office, or a better kitchen and living area, we’ll design something that works with your existing home.

Kurrajong attracts families who want space, clean air and a tight community while staying within reach of Richmond and Penrith. Property values here have climbed steadily as more people discover the area, and a well designed extension can add $150,000 to $300,000 to your home’s value. Instead of dealing with the stress and expense of buying bigger, you can create exactly what you need on the block you already 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."

"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!"

Bushfire regulations and heritage considerations can also apply in parts of the area. We manage the full approval process for you, including all documentation and council liaison.

Can you work with sloping blocks in Kurrajong?

Absolutely. Most homes in Kurrajong sit on sloping blocks with valley views, and we’ve completed many extensions on challenging sites.
