Home Extensions Glenfield
Built For The Way You Live
Glenfield is home to a mix of post war fibro cottages and brick homes from the 1960s and 70s, mostly sitting on quarter acre blocks that offer genuine extension potential. Many original homes feature modest living spaces, dated kitchens and limited storage that no longer suit growing families. With land at a premium across Sydney, extending your existing Glenfield home makes far more sense than trying to sell and buy bigger in the current market.
We’ve completed dozens of extensions throughout Glenfield and surrounding suburbs like Casula and Ingleburn, transforming cramped weatherboard homes into modern family spaces. Our team knows the local housing stock inside out, from foundation types to common structural challenges in homes from this era. Whether you’re adding a second storey to capture more space or extending out the back for an open plan kitchen and living area, we handle every trade and every detail from start to finish.
Glenfield families love the access to schools, parks and the train station, but many homes haven’t kept pace with modern living standards. A well designed extension can add $150,000 to $250,000 in value while giving you the extra bedrooms, bathrooms or living space your family actually needs. Rather than moving away from established neighbours and local connections, extending lets you stay in the suburb you know while finally getting the home that works for your lifestyle.

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."
Amanda
"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!"
Angela
"Fantastic! Monstructions did an amazing job on my home extension, all the boys that worked on my house were professional and polite, and their quality of work was second to none. 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."

Smaller single room additions can be completed faster, while full second storey builds take longer. We provide a detailed timeline during the quoting process so you know exactly what to expect.
Do I need council approval for a home extension in Glenfield?
Yes, most home extensions in Glenfield require either Development Approval or a Complying Development Certificate from Liverpool City Council. Some minor additions may qualify for exempt development, but this depends on size, setbacks and other planning controls. Our team manages the full approval process for you, including all drawings, documentation and council liaison.
Can you extend older fibro homes in Glenfield?
Absolutely. We’ve extended plenty of original fibro and weatherboard homes throughout Glenfield, and we’re experienced in working with older construction methods. The key is a proper structural assessment upfront to determine the best way to tie in new work with existing foundations and framing. Many fibro homes actually extend beautifully once you have a builder who understands the existing structure.
