Home Extensions St Ives
Built For The Way You Live
St Ives is home to a mix of brick and tile homes from the 1960s through to the 1980s, with many properties sitting on generous quarter to half acre blocks. These family homes often need more living space, updated layouts or better connection to outdoor areas. An extension lets you stay in this quiet, family friendly suburb without the hassle and expense of moving.
We’ve built extensions across St Ives and throughout the Upper North Shore, working with everything from split level homes to classic single storey designs. Our team understands the local building styles and how to add space that feels like it’s always been part of the home. From open plan kitchen extensions to second storey additions, we handle projects of all sizes.
St Ives families value the local schools, bushland setting and tight knit community feel. With property values holding strong and good homes in short supply, extending your current house makes more financial sense than buying something bigger. A well designed extension gives you the space you need while keeping you in the suburb 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."

"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 St Ives?

Do I need council approval for a home extension in St Ives?
Most extensions in St Ives require either a Development Application or Complying Development Certificate from Ku-ring-gai Council. Some smaller projects may fall under exempt development, but this is rare for most extensions. We manage the entire approval process on your behalf, including plans, submissions and any council queries.
Can you extend split level homes in St Ives?
Yes, we regularly work with split level homes which are common throughout St Ives. These homes require careful planning to manage different floor levels and roof lines, but they’re ideal candidates for extensions. We design additions that work with the existing structure and terrain rather than fighting against it.

Yes we service St Ives and all surrounding suburbs. Call 1300 098 730 to discuss your project.
