Home Extensions Upper North Shore
Built For The Way You Live
The Upper North Shore is filled with solid brick homes built between the 1950s and 1980s, many sitting on generous blocks that offer plenty of room to extend. These homes were built for a different era, with smaller living areas, closed off kitchens and limited connection to the backyard. An extension transforms these well built properties into modern family homes without the cost and stress of moving.
We’ve completed extensions right across the Upper North Shore, from Pymble and Turramurra through to Killara, Lindfield, Roseville and St Ives. Our team knows the local council requirements and understands how to work with the sloping blocks and established gardens common throughout the area. Every project is managed by licensed builders who live and work locally.
Upper North Shore families value the school zones, tree lined streets and established community, which is why most prefer to extend rather than relocate. With median house prices well above $2 million in suburbs like Wahroonga and Pymble, a well designed extension offers far better value than buying a larger home. Adding 50 to 100 square metres can give you the extra bedrooms, open plan living and outdoor connection your family needs while keeping you in the area you 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."
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."

How long does a home extension take in Upper North Shore?
Most extensions take between 3 to 6 months from council approval through to final handover, depending on the size and complexity of your project. We’ll give you a clear timeline during the quoting process and keep you informed at every stage. Weather, council inspections and material availability can all affect timing, but we plan for these factors upfront.
Do I need council approval for a home extension in Upper North Shore?
Most extensions require either a Development Application or Complying Development Certificate from your local council in NSW. The approval process depends on your property, the size of your extension and local planning controls. We manage the full approval process for you, working with our trusted architects and certifiers to get your project approved as quickly as possible.
Can you extend on a sloping block in Upper North Shore?
Yes, we regularly build extensions on sloping sites throughout the Upper North Shore. Many homes in Killara, Turramurra and St Ives sit on blocks with significant fall, which actually creates opportunities for clever design and additional under floor storage. Our team has the engineering knowledge and construction experience to handle complex sites safely and cost effectively.
