Home Extensions The Oaks
Built For The Way You Live

The Oaks features a mix of older brick homes from the 70s and 80s alongside newer acreage properties, many sitting on generous blocks that offer real potential for extension. Many of these homes were built with smaller living areas and dated floor plans that no longer suit how families live today. With land at this size hard to find closer to Sydney, extending your existing home makes far more sense than moving.

We’ve completed extensions throughout The Oaks and nearby areas like Oakdale and Picton, working with everything from single level brick homes to weekenders that need more space. Our team understands the local building requirements and how to design additions that work with the semi rural character of the area. From extra bedrooms and open plan living areas to second storey additions that capture the rural views, we handle projects of all sizes.

The Oaks attracts families who want space and a relaxed lifestyle without being too far from Sydney, and property values have climbed steadily over recent years. A well designed extension lets you create the home you need while keeping the land and location you’ve already invested in. Whether it’s accommodating a growing family or creating a more functional layout, the right extension delivers real value in this tightly held market.

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!"
