Home Extensions Warriewood
Built For The Way You Live
Warriewood is home to a real mix of housing stock, from older brick and tile homes built in the 70s and 80s through to newer townhouses and duplex developments. Many properties sit on decent sized blocks around 500 to 700 square metres, giving you good scope for an extension without eating up all your outdoor space. With many of these older homes featuring smaller living areas and dated layouts, an extension makes far more sense than moving, especially given today’s property prices.
We’ve completed extensions right across Warriewood and neighbouring suburbs like Narrabeen and Mona Vale, working with families who need more room as kids grow or parents want to age in place. Our team knows the local building requirements and what works with the typical housing stock in the area. We handle everything from single storey rear extensions to full second storey additions, all designed to match your existing home and suit how your family actually lives.
The Northern Beaches lifestyle keeps people in Warriewood long term, with the beach, Warriewood Square and good schools all close by. Property values have climbed steadily over the past decade, making a well planned extension a smart investment that adds serious value to your home. You get the extra space you need without the massive disruption and cost of selling and buying elsewhere.

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 Warriewood?

Do I need council approval for a home extension in Warriewood?
Most extensions in Warriewood require either a Development Application or Complying Development Certificate from Northern Beaches Council. Some minor additions may qualify for exempt development, but this is rare. Our team manages the entire approval process for you, including all architectural drawings and submissions.
Can I add a second storey to my Warriewood home?
Many Warriewood homes are suitable for a second storey addition, particularly the older single level brick homes on larger blocks. We’ll assess your existing structure, check local height restrictions and floor space ratio limits, then design an addition that works with your property. A structural engineer inspects your home as part of our standard process.
