Home Extensions Richmond
Built For The Way You Live
Richmond’s housing stock ranges from classic 1960s and 70s fibro and brick homes on generous blocks through to newer estates from the 1990s and 2000s. Many properties sit on quarter acre blocks or larger, giving you plenty of room to extend rather than relocate. With land sizes like these, a well planned extension makes far more sense than selling up and moving.
We’ve completed extensions right across Richmond and the Hawkesbury area, from single storey additions that open up living spaces to full second storey builds that give growing families the extra bedrooms they need. Our team knows the local building requirements and works with council regulations to get your project approved and built properly. Every extension we build is designed to match the existing home while creating functional new spaces for how you actually live.
Richmond families love the space and lifestyle this area offers, but many older homes weren’t built for modern family life. Adding a quality extension lets you stay in the community you know while getting the space you need, whether that’s an extra bedroom, a bigger kitchen or an open plan living area. With Richmond’s property market staying strong, the right extension adds serious value while letting you enjoy the benefits now instead of waiting to move.

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 much does a home extension cost in Richmond?

How long does a home extension take in Richmond?
Most home extensions in Richmond take between 3 to 6 months from development approval through to final handover. The timeline depends on the scope of your project and the complexity of the build. We’ll give you a clear schedule during the planning phase so you know exactly what to expect.
Do I need council approval for a home extension in Richmond?
Yes, most home extensions in Richmond require either Development Application approval or a Complying Development Certificate through Hawkesbury City Council. The approval pathway depends on your property and the scope of work. Our team manages the entire approval process for you, liaising with council and certifiers to get your extension approved.
Can you extend older fibro homes in Richmond?
Absolutely. Many Richmond homes were built with fibro construction in the 60s and 70s, and we regularly extend these properties. We assess the existing structure, make any necessary modifications to support the new extension, and ensure everything meets current building standards. The key is proper planning and experienced builders who understand how to work with these older building methods.
