Home Extensions North St Ives
Built For The Way You Live
North St Ives features predominantly brick and tile homes built through the 1970s and 1980s, with many sitting on generous blocks ranging from 700 to 1200 square metres. These original family homes were designed for a different era, with closed off kitchens, separate living areas and limited connection to outdoor spaces. An extension allows you to modernise the layout without sacrificing the established gardens and quiet streets that make this area so appealing.
We’ve completed extensions across North St Ives and throughout St Ives, Pymble and Gordon, working with the typical sloping blocks and bushland surrounds common to this part of the Upper North Shore. Our team understands how to design additions that respect the leafy character of the area while creating the open plan living spaces families need today. Every project is managed by our licensed builders from concept to completion.
Families move to North St Ives for the quality schools, large blocks and proximity to nature reserves, often staying for decades as their needs change. Rather than uprooting to find more space, a well designed extension lets you stay in the community you know while adding real value to your property. The local market rewards homes that blend character with modern functionality, making an extension a smart 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."

Do I need council approval for a home extension in North St Ives?
Most extensions in North St Ives require either a Development Application or Complying Development Certificate through Ku-ring-gai Council. Our team manages the full approval process including plans, documentation and any variations needed. We know the local planning rules well and work to get your project approved efficiently.
Can you extend on sloping blocks in North St Ives?
Absolutely, we regularly work with the sloping sites common throughout North St Ives and the surrounding Upper North Shore.

Our team designs with the natural fall of your block to manage costs while creating functional living areas.
