Home Extensions Kellyville Ridge
Built For The Way You Live
Kellyville Ridge is one of the newer growth areas in the Hills District, with most homes built from the early 2000s onwards on blocks typically between 400 and 600 square metres. Many properties were built by volume builders with standard floor plans that worked when families were smaller, but now need more space as kids grow or work from home becomes permanent. An extension makes far more sense than selling and moving when you’re already in established streets close to schools and local shops.
We’ve completed dozens of extensions throughout Kellyville Ridge and neighbouring areas like Beaumont Hills and The Ponds, working primarily with families who need an extra bedroom, larger living areas or a dedicated home office. The typical build here involves ground floor extensions that flow into existing living spaces, often opening up to the backyard with stacking doors. We know the local building codes inside out and have strong relationships with certifiers who understand what works in this area.
Property values in Kellyville Ridge have climbed steadily over the past decade as the area matures and public transport options improve with the Metro Northwest nearby. Adding 40 to 60 square metres of quality living space can increase your home’s value by $150,000 to $250,000 while giving your family the room you actually need. Most families we work with here say they wish they’d extended sooner rather than putting up with cramped conditions for years.

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 long does a home extension take in Kellyville Ridge?
Most home extensions in Kellyville Ridge take between 3 to 6 months from council approval through to final handover. The timeline depends on the size and complexity of your project, with ground floor extensions typically faster than second storey builds. We provide a clear construction schedule at the start so you know exactly what to expect.
Do I need council approval for a home extension in Kellyville Ridge?
Yes, most home extensions in Kellyville Ridge require either Development Approval or a Complying Development Certificate from The Hills Shire Council. Some smaller projects may qualify for exempt development, but this is rare for liveable extensions. Our team manages the entire approval process for you, working with our town planner and certifier to get everything through as quickly as possible.
Can I extend on a sloping block in Kellyville Ridge?
Absolutely, many blocks in Kellyville Ridge have some slope to them and we work with this regularly. The key is designing the extension to work with the fall rather than against it, which might mean split levels or raised flooring in certain areas. We assess every site individually and provide solutions that work structurally and stay within budget.
