Home Extensions Narraweena
Built For The Way You Live

Narraweena is filled with solid brick homes from the 1960s and 70s, many sitting on decent sized blocks between 550 and 700 square metres. These homes were built for a different era, and many families find themselves needing more living space, a second bathroom, or a better connection to the backyard. An extension makes far more sense than moving, especially when you’ve got an established garden and you’re close to schools and shops.

We’ve completed extensions throughout Narraweena and right across the Northern Beaches, working with the typical housing stock in this area. Whether it’s pushing out the back for an open plan kitchen and living area, adding a second storey, or creating a ground floor addition with a new main bedroom, we know what works on these blocks. Our team manages the entire process including council approvals, which matters when you’re dealing with Northern Beaches Council requirements.

Narraweena sits in a quiet pocket between Collaroy and Brookvale, with good schools and local shops along Pittwater Road. Property prices have climbed steadily here, and families are choosing to renovate rather than sell and move further out. A well designed extension adds serious value to your home and gives you the space you actually need, without the stress and cost of buying somewhere else.

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 Narraweena?

Most home extensions take between 3 to 6 months from DA approval through to final handover, depending on the scope of work. Design and council approval adds another 2 to 4 months before construction starts. We’ll give you a realistic timeline based on your specific project during the initial consultation.

Do I need council approval for a home extension in Narraweena?

Most extensions in Narraweena require either a Development Application or Complying Development Certificate from Northern Beaches Council. The approval pathway depends on your extension size, setbacks, and site constraints. Our team manages the full approval process including plans, submissions, and any required documentation.

Can I extend up on a sloping Narraweena block?

Many Narraweena properties sit on sloping blocks, which can actually work in your favour for a second storey or split level extension. We assess your site levels, existing foundation, and council height limits to determine the best approach. Sloping blocks often allow for better design outcomes with good natural light and views.
