Home Extensions Granville
Built For The Way You Live

Granville has a real mix of older brick homes from the 1950s and 60s alongside weatherboard cottages and more recent townhouse developments. Most blocks sit around 550 to 650 square metres, which gives you decent space to extend without taking over the entire backyard. The homes here were built when families were smaller and living rooms were formal, so adding a proper family area or extra bedroom makes complete sense for how people actually live today.

We’ve worked on plenty of extensions throughout Granville and across to Merrylands, Harris Park and Auburn over the years. Most clients want to add a second living area that opens to the backyard, or they’re converting garages and building up to create extra bedrooms for growing families. The older homes here have good bones, which means they handle extensions well once the footings and structure are properly assessed.

Granville sits close to Parramatta with excellent train access and local schools, which is why families tend to stay put rather than move when they need more space. The property market here rewards well planned extensions because buyers want move in ready homes with modern layouts. Adding 40 to 60 square metres of quality living space typically returns more value than the build cost, especially when you’re creating open plan areas that connect indoors with outdoors.

Don't Take Our Word For It

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 Granville?

A single room addition might be done in 10 to 12 weeks, while a large two storey extension can take closer to 6 months. We give you a detailed timeline upfront so you know exactly what to expect.

Do I need council approval for a home extension in Granville?

Most extensions in Granville require either a Development Application or Complying Development Certificate from Parramatta Council. Some very minor additions might fall under exempt development, but anything involving structural work or adding floor space usually needs approval. We manage the full approval process including plans, engineering, and submissions so you don’t have to deal with council yourself.

Can you extend older brick homes in Granville?

Absolutely, we extend older brick homes in Granville all the time. The key is getting a proper structural assessment first to check the existing footings and make sure the old brickwork can tie in properly with the new build. Most 1950s and 60s homes here are solid enough to handle a quality extension once the engineering is done right.
