Home Extensions Bayview
Built For The Way You Live
Bayview homes sit on some of the most generous blocks on the Northern Beaches, with many properties on acre blocks or larger bush settings from the 1970s and 1980s. These original single storey homes were built for a different era, and many families now need additional living space, home offices or larger kitchens. With land this valuable and locations this private, extending your existing home makes far more sense than selling and moving.
We’ve completed extensions throughout Bayview and neighbouring Ingleside, working with the sloping sites and bushland settings that make this area unique. Our team knows how to design additions that complement the relaxed, rural character while meeting modern family needs. From ground floor expansions to second storey additions that capture water views, we handle the full scope of work.
Bayview offers a lifestyle many families don’t want to leave, with acreage living just 30 minutes from the CBD and close to beaches. Property values here reflect the land size and location, making a well designed extension an excellent investment. Adding 60 to 100 square metres of quality living space typically returns strong value while letting you stay in the community you love.

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!"
