Home Extensions Northern Beaches
Built For The Way You Live
Most homes across the Northern Beaches were built between the 1960s and 1980s, with modest layouts on decent sized blocks that leave plenty of room for an extension. The original fibro and brick homes in suburbs like Dee Why, Narrabeen and Mona Vale were designed for smaller families and lack the open plan living spaces today’s homeowners need. An extension makes far more sense than moving when you’ve already got the location and land.
We’ve completed extensions right across the Northern Beaches, from ground floor additions in Freshwater and Curl Curl through to full double storey renovations in Avalon and Newport. Our team knows the local building regulations inside out, including the specific height restrictions and setback requirements that apply across different parts of the peninsula. Whether you’re in Manly, Collaroy or anywhere in between, we’ll design an extension that works with your existing home and maximises your site.
Property values on the Northern Beaches continue to climb, making it far more cost effective to extend your current home than to buy something bigger in the same area. Families want to stay close to the beaches, schools and community they know, but they need more space as kids grow or parents work from home. A well designed extension can add $200,000 to $400,000 in value while giving you the extra living space, bedroom or home office you actually need.

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!"

Can I build a second storey in Northern Beaches?
Second storey additions are possible in most Northern Beaches suburbs, but there are strict height limits that vary depending on your zoning and how close you are to the coast.
