Home Extensions North Rocks
Built For The Way You Live
North Rocks homes were mostly built between the 1970s and 1990s, with typical blocks ranging from 550 to 700 square metres. The original brick homes often feature three bedrooms and single living areas that no longer suit modern family life. Rather than moving away from established streets and good schools, extending your current home makes practical and financial sense.
We’ve completed dozens of extensions throughout North Rocks and neighbouring suburbs like Carlingford and Baulkham Hills over the past decade. Our team knows the local housing stock inside out, from the typical slab on ground construction to the council requirements specific to The Hills Shire. Whether you need an extra bedroom, larger kitchen or second living area, we design extensions that look like they’ve always been part of your home.
North Rocks offers excellent schools, parks and convenient access to Castle Towers and Macquarie Centre, making it a popular area for growing families. Properties here hold their value well, and a quality extension can add significant equity while giving you the extra space you need. Many of our clients choose to extend rather than chase a bigger mortgage in a less established area.

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!"

How much does a home extension cost in North Rocks?
A single room addition typically starts from around $80,000, while a full ground floor extension starts from $150,000 depending on finishes and complexity. Second storey additions generally begin at $250,000 due to structural requirements. We provide a free, detailed quote after assessing your home and understanding exactly what you need.
How long does a home extension take in North Rocks?
Most home extensions take between 3 to 6 months from council approval through to final handover, depending on the size and complexity of your project. The council approval process with The Hills Shire typically adds another 8 to 12 weeks before construction begins. We’ll give you a realistic timeline during your initial consultation.
Do I need council approval for a home extension in North Rocks?
Most extensions in North Rocks require either a Development Application or Complying Development Certificate through The Hills Shire Council. Even smaller additions need to comply with setbacks, height limits and other planning controls. Our team manages the entire approval process for you, working with experienced designers and certifiers who know the local requirements.
Can you extend older brick homes in North Rocks?
Absolutely, and we do it regularly throughout North Rocks and surrounding suburbs. Older brick homes from the 70s and 80s are well suited to extensions once we assess the existing foundations and structure. We make sure new work matches the existing brickwork and roofline so everything looks cohesive.
