Home Extensions Freshwater
Built For The Way You Live
Freshwater’s housing stock is dominated by post war fibro and brick homes from the 1950s and 60s, many on decent sized blocks between 550 and 700 square metres. These original beach houses were built for a different era, with small kitchens, limited living space and often just one bathroom. An extension makes perfect sense when you’ve got the land and a solid structure to work with.
We’ve completed extensions throughout Freshwater and the surrounding Northern Beaches suburbs, from single storey rear additions to full second storey builds. Most of our Freshwater projects involve opening up the back of the house to create better flow between kitchen, dining and outdoor areas. We also regularly add extra bedrooms and bathrooms upstairs to make the most of ocean glimpses and capture the sea breeze.
Freshwater sits in one of the most tightly held pockets of the Northern Beaches, with families reluctant to leave once they’re established near the beach and village. Property prices reflect this demand, which makes extending your existing home a smart financial decision compared to buying something larger. A well planned extension lets you stay in the community your kids know while creating a home that actually works for your family.

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 Freshwater?

The timeline depends on the scope of work, with single storey additions on the quicker end and full second storey builds taking longer. We’ll give you a clear schedule once we’ve finalised the design and locked in approvals.
Do I need council approval for a home extension in Freshwater?
Yes, most home extensions in Freshwater require either a Development Application or Complying Development Certificate from Northern Beaches Council. The approval pathway depends on your property’s zoning, the size of the extension and setbacks from boundaries. We manage the entire approval process on your behalf, from preparing documentation through to lodgement and dealing with any council requests.
Can I add a second storey to my Freshwater home?
Most homes in Freshwater can accommodate a second storey addition, particularly the solid brick and block homes from the 60s and 70s. We assess your existing structure during the initial consultation to confirm it can support the additional load. Many of our Freshwater second storey projects are designed to capture ocean views and breezes while staying within council height limits.
