Home Extensions Roseville Chase
Built For The Way You Live
Roseville Chase is known for its post war homes and brick residences built mainly through the 1950s and 60s, sitting on generous blocks that back onto the Lane Cove National Park. Many of these original homes feature smaller living areas and dated layouts that no longer suit modern family life. An extension allows you to keep your established address while creating the space your family actually needs.
We’ve completed numerous extensions throughout Roseville Chase and the surrounding North Shore suburbs, working with the natural slope of blocks and the planning requirements around the national park. Our team understands the local character and how to design additions that complement the existing streetscape while maximising your floor plan. Every project is managed by our licensed builders from concept right through to completion.
Families love Roseville Chase for the school zones, the bushland setting and the quiet streets, which makes moving away difficult when you need more room. The proximity to the national park and strict planning controls mean well designed extensions hold their value exceptionally well. Adding a quality extension is often more practical and cost effective than selling and buying elsewhere in the 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 long does a home extension take in Roseville Chase?

The council approval process can add another 8 to 12 weeks before construction starts. 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 Roseville Chase?
Most home extensions in Roseville Chase require either a Development Application or Complying Development Certificate from Ku-ring-gai Council. The proximity to Lane Cove National Park can also trigger additional planning considerations. Our team manages the full approval process on your behalf, working with certifiers and planners to get your project approved.
Can I extend on a sloping block in Roseville Chase?
Absolutely. Many homes in Roseville Chase sit on sloping sites that back onto bushland, and we regularly design extensions that work with the natural fall of the land. Our team has extensive experience with retaining walls, stepped foundations and designs that minimise cut and fill. The slope often creates opportunities for additional storage or under house areas that add real value.
