Home Extensions Bilgola Plateau
Built For The Way You Live
Bilgola Plateau homes were largely built between the 1960s and 1980s on generous blocks, many around 600 to 800 square metres. These original brick and weatherboard homes typically feature three bedrooms and single living areas that no longer suit how modern families actually live. An extension makes far more sense than moving when you’ve got the land and location already locked in.
We’ve completed dozens of extensions across Bilgola Plateau and neighbouring suburbs like Newport and Avalon, working with the area’s mix of split level and single storey homes. Our team knows how to work with the slope and elevation that defines properties up here, designing extensions that complement the original build. We handle all trades in house and coordinate every aspect of the build so you’ve got one point of contact throughout.
Families stay in Bilgola Plateau for the schools, the quiet streets and easy access to both Bilgola and Newport beaches. With median house prices well over $2 million, adding a quality extension is a smart investment that keeps you in the area you love. Most of our clients here are adding extra living space, a second bathroom or creating proper master suites that their original floor plans simply don’t provide.

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!"
