Home Extensions Beacon Hill
Built For The Way You Live
Beacon Hill is predominantly made up of brick homes built between the 1960s and 1980s on generous blocks, many over 600 square metres. These solid older homes were built with smaller living spaces and limited open plan areas, making them perfect candidates for a well designed extension. Many properties sit on elevated blocks with good potential for adding extra living space or a second level.
We’ve completed dozens of extensions throughout Beacon Hill and nearby suburbs like Narraweena and Cromer, working with families who need more room but don’t want to leave the area. Our team understands the local housing stock and what works best for these older Northern Beaches homes. From single storey rear additions to full second storey builds, we handle projects of all sizes across the peninsula.
Beacon Hill offers a quiet family lifestyle with good schools, parks and easy access to both Warringah Mall and the northern beaches. Property prices have climbed steadily over recent years, and a quality extension can add serious value while giving you the extra space your family needs. Rather than buying up in today’s market, extending your current home often makes far better financial sense.

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."
Amanda
"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!"
Angela
"Fantastic! Monstructions did an amazing job on my home extension, all the boys that worked on my house were professional and polite, and their quality of work was second to none. From drawings to completion it was a breeze working with them. They were easy to work with and extremely efficient and professional. Thank you for all the hard work and effort, I will recommend you to everyone I know."
