Home Extensions North Shore
Built For The Way You Live
The North Shore is dominated by post war brick homes and 1960s to 1980s builds sitting on decent sized blocks, particularly through Chatswood, Roseville, and Killara. These older homes often have good bones but lack the open plan living and indoor outdoor flow that modern families need. With land prices what they are across the lower North Shore, extending your existing home makes far more financial sense than selling and moving.
We’ve completed extensions right across the North Shore, from single storey rear additions in Lindfield and Lane Cove to full second storey builds in St Leonards and Artarmon. Our team knows the local council requirements for Willoughby and Lane Cove councils inside out, which means smoother approvals and fewer headaches for you. Whether you’re in Northbridge, Crows Nest, or Greenwich, we’ve worked on homes just like yours.
North Shore property values have held strong even through uncertain markets, and a well designed extension can add significant equity to your home. Families here want to stay in the area for the schools and community, which drives demand for larger, updated homes. Adding a second storey or extending out the back lets you get the space you need without leaving the neighbourhood 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."

FAQS
Got a question?
How much does a home extension cost in North Shore?

How long does a home extension take in North Shore?
Most home extensions take between 3 to 6 months from DA approval through to final handover, depending on the size and complexity of the build. Council approval timeframes vary between Willoughby and Lane Cove councils, usually taking 8 to 12 weeks. We’ll give you a realistic timeline during our initial consultation based on your specific project.
Do I need council approval for a home extension in North Shore?
Most extensions require either a Development Application or Complying Development Certificate through your local council in NSW. The type of approval depends on the size and nature of your extension, and whether your property has any heritage or environmental constraints. We manage the full approval process for you, including all drawings, documentation, and council liaison.
Can I add a second storey to my North Shore home?
Most North Shore homes can support a second storey addition, but it depends on your existing structure, block size, and council height limits. Many post war brick homes need some structural reinforcement, which we assess during the design phase. We’ll arrange a structural engineer’s report and handle all the technical requirements to make sure your second storey is built safely and approved correctly.
