Home Extensions Phillip Bay
Built For The Way You Live

Phillip Bay homes mainly date from the 1960s and 70s, with brick and fibro construction on decent sized blocks that offer real potential for extending. Many of these original homes have smaller living areas and outdated layouts that no longer work for modern families. An extension is often the smartest way to create the space you need without leaving a location this close to the beach.

We’ve completed extensions throughout Phillip Bay and the surrounding Northern Beaches suburbs, working with the typical post war housing stock in the area. Our team understands how to work with existing brick and timber construction, matching materials and ensuring the new addition feels like it’s always been part of the home. Every project is managed by our licensed builders from council approval through to completion.

Phillip Bay’s proximity to Long Reef Beach and the headland makes it a tightly held pocket where families want to stay long term. With property prices reflecting the beachside location, extending your current home often makes more financial sense than buying bigger in the same area. A well planned extension not only gives you the space your family needs but adds serious value to your property.

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!"
