Home Extensions Chatswood West
Built For The Way You Live
Chatswood West is dominated by modest brick homes and weatherboard cottages built through the 1950s and 1960s, sitting on manageable blocks typically around 550 to 700 square metres. Many of these original homes feature compact layouts with small kitchens and limited living space that no longer suit modern family needs. An extension is often the smartest way to get the space you need without leaving a well connected, established neighbourhood.
We’ve completed extensions throughout Chatswood West and nearby suburbs like Artarmon and Lane Cove, working with the constraints of older foundations and tighter blocks. Our team knows how to maximise space on these lots while respecting setbacks and maintaining natural light. Whether it’s opening up the rear of the home or adding a second level, we design extensions that feel like they’ve always belonged.
Chatswood West offers excellent access to the CBD and quality schools, which keeps property values strong and demand high. Extending your current home lets you capture that value and create the lifestyle you want without the stress and expense of moving. A well planned extension can add significant equity while giving you the extra bedroom, bigger kitchen or open plan living area your family actually needs.

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!"

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."

We manage the full approval process including plans, submissions and liaising with council on your behalf.
Can I add a second storey to my Chatswood West home?
Many of the older single storey homes in Chatswood West are suitable for a second storey addition, though it depends on your existing foundations and structural capacity. We conduct a thorough assessment early in the process to determine what’s feasible and cost effective for your property.
