Home Extensions Queenscliff
Built For The Way You Live

Queenscliff homes are predominantly original beach cottages and fibro houses from the 1950s and 60s, built on reasonably sized blocks close to the beach. Many properties sit on 500 to 700 square metre blocks, which gives good scope for extending without eating up all your outdoor space. These older homes often have small living areas and limited storage, making them perfect candidates for a well planned extension.

We’ve completed dozens of extensions across Queenscliff and surrounding beaches, from ground floor additions that open up living spaces to the north facing backyard through to full second storey builds that capture ocean views. Most homeowners want better connection between indoor and outdoor areas, plus an extra bedroom or bathroom to suit growing families. The goal is always to respect the beachside character while creating a home that works for modern family life.

Property prices in Queenscliff reflect the suburb’s beachfront location and tight community feel, with many families choosing to extend rather than chase bigger homes further inland. Adding a quality extension typically costs far less than buying a larger property in the area, and you get to stay in a location within walking distance to the beach and good schools. A thoughtfully designed extension can add $200,000 to $400,000 in value depending on what you build.

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."

Manly

"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 Queenscliff?

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

Most extensions in Queenscliff require either a Development Application or Complying Development Certificate through Northern Beaches Council. The approval requirements depend on the size and type of extension you’re planning. We manage the full approval process for you, including all documentation and any required consultants.

Can I add a second storey to my Queenscliff cottage?

Yes, many older Queenscliff cottages are suitable for a second storey addition, particularly if you want to capture ocean or headland views. We assess your existing foundations and structure to determine what’s required. Most fibro and weatherboard cottages need some structural work, but it’s absolutely achievable and often the best way to add space without losing backyard.
