Home Extensions Denistone
Built For The Way You Live
Denistone is filled with solid brick homes from the 1950s through to the 1980s, mostly sitting on generous 600 to 800 square metre blocks. These homes were built for a different era, with smaller living areas and modest kitchens that no longer suit how families live today. An extension makes far more sense than moving, especially when you’ve got established gardens, great neighbours and a home in a location this convenient.
We’ve completed extensions throughout Denistone and right across the Upper North Shore, working with homeowners to add modern living spaces, open plan kitchens and additional bedrooms. Our team knows these older brick homes well and understands how to match existing materials while creating spaces that feel completely fresh. Every project is managed in house, from the first design meeting through to council approvals and final construction.
Denistone offers excellent schools, easy access to the city and a quiet residential feel that families value highly. Property prices reflect this demand, which makes renovating and extending a smart investment compared to buying something bigger in the same area. A well designed extension can transform a tired three bedroom into a modern family home worth significantly more than your total investment.

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."

We’ll give you a clear timeline during the quoting process.
Do I need council approval for a home extension in Denistone?
Most home extensions require either a Development Application or Complying Development Certificate through Ryde Council. Minor internal alterations might not need approval, but any structural changes or additions to your home’s footprint will require proper consent. We manage the entire approval process for you, working with our architects and certifiers to get your project approved.
Can you match face brick on older Denistone homes?
Yes, matching existing face brick is something we do regularly on Denistone homes from the 50s, 60s and 70s. We source bricks that match as closely as possible, and experienced bricklayers know how to blend new work with old. Sometimes homeowners choose to render or clad the entire home for a complete modern update instead.
