Home Extensions Merrylands
Built For The Way You Live
Merrylands has plenty of brick homes from the 1960s and 70s sitting on decent sized blocks, typically 550 to 700 square metres. These solid post war homes were built when families needed less space, and most have good bones but lack the living areas, storage and extra bedrooms today’s families require. An extension makes far more sense than selling up and moving when you’ve got the land and a good location.
We’ve completed dozens of extensions across Merrylands and the surrounding Western Sydney suburbs, from single storey rear additions to full second storey builds. Our team knows the local housing stock well and understands what works on these blocks, from managing side setbacks to designing additions that complement the original home. Every project is managed by our licensed builders who coordinate trades, handle inspections and keep everything running on schedule.
Merrylands offers excellent value compared to inner suburbs, with good schools, transport links to Parramatta and the city, and established amenities along Merrylands Road and McFarlane Street. Families are choosing to stay and extend rather than chase bigger homes further out, and a well designed extension can add $150,000 to $250,000 in property value. You get the extra space you need while staying in a suburb where you’ve put down roots.

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 Merrylands?
Most home extensions in Merrylands take between 3 to 6 months from council approval through to final handover. The timeline depends on the scope of work, whether it’s a single storey or double storey build, and any site specific factors. We provide a clear schedule at the start and keep you updated throughout the build.
Do I need council approval for a home extension in Merrylands?
Yes, most home extensions in Merrylands require either a Development Application or Complying Development Certificate through Cumberland Council. Some smaller additions may qualify for exempt development, but this depends on setbacks, height and other planning rules. Our team manages the entire approval process including plans, documentation and council liaison so you don’t have to deal with the paperwork.
Can you extend older brick homes in Merrylands?
Absolutely, we extend older brick homes all the time across Merrylands and they’re generally well suited to extensions. Most 60s and 70s brick homes have solid foundations and good structural integrity, making them ideal candidates for both ground floor and second storey additions. We assess the existing structure first and design the extension to work with what’s already there.
