Home Extensions Cherrybrook
Built For The Way You Live
Cherrybrook’s housing stock is largely made up of brick homes built from the 1970s through to the 1990s on generous blocks, many around 700 to 1000 square metres. These solid family homes were built for a different era, and many now feel cramped as families grow or work from home becomes permanent. An extension lets you stay in a suburb you love without the upheaval and expense of moving.
We’ve completed dozens of extensions across Cherrybrook and neighbouring suburbs like West Pennant Hills and Thornleigh, working with families who need more space but want to keep their kids in local schools. Whether it’s adding a ground floor living area, a second storey with extra bedrooms, or extending out the back for an open plan kitchen and dining zone, we build additions that feel like they’ve always been part of the home. Our team knows the local building requirements and works with homeowners to design practical spaces that suit how families actually live.
Cherrybrook’s strong school catchments and family friendly character mean property values hold firm, even when the market shifts elsewhere. Extending your existing home is often more cost effective than buying a larger property in the area, especially when you factor in stamp duty and moving costs. A well planned extension can add significant value while giving you the space you need right now.

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!"

How long does a home extension take in Cherrybrook?

Smaller single room additions are usually quicker, while second storey builds or large ground floor extensions take longer. We’ll give you a clear timeline during the planning stage so you know exactly what to expect.
Do I need council approval for a home extension in Cherrybrook?
Most home extensions in Cherrybrook require either a Development Application or Complying Development Certificate through Hornsby Council. Some smaller additions may qualify for exempt development, but this depends on setbacks, height and other planning controls. We manage the full approval process for you, working with experienced designers and certifiers to get your extension approved.
Can I add a second storey to my Cherrybrook home?
Most homes in Cherrybrook are structurally suitable for a second storey addition, but it depends on your existing foundations and framing. We arrange a structural assessment early in the process to confirm feasibility and factor any strengthening work into the quote. Second storey additions are popular in the area because they maximise space without losing your backyard.
