Home Extensions Whalan
Built For The Way You Live

Whalan features mostly brick homes built from the 1960s through to the 1980s, with typical blocks around 550 to 650 square metres. These solid post war homes were built with smaller rooms and limited living space, making them perfect candidates for a well planned extension. With good bones and decent land size, extending your Whalan home is often more cost effective than buying something bigger in the same area.

We’ve completed extensions throughout Whalan and neighbouring suburbs like Mount Druitt and Emerton, working with the local housing stock to create additions that feel like they’ve always been there. Our team knows these homes inside out, from the original fibro ceilings to the way the plumbing was run back in the day. Each project is managed by licensed builders who understand what works for families in this part of western Sydney.

Whalan sits close to shops, schools and transport, making it a practical base for families who want to stay in the area long term. The local property market has seen steady growth, and adding a second living area or extra bedrooms can significantly increase your home’s value while giving your family the space you actually need. Rather than upsizing and taking on a bigger mortgage, extending your existing Whalan home lets you stay in the community you know.

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!"

FAQS

Got a question?

How much does a home extension cost in Whalan?

A single room addition typically starts from $80,000, while a full ground floor extension begins around $150,000. Second storey additions generally start from $250,000 depending on size and finishes. We provide a detailed free quote after assessing your property and understanding what you need from the space.

How long does a home extension take in Whalan?

Most home extensions take between 3 to 6 months from council approval through to final handover, depending on the size and complexity of the build. Smaller single room additions can be quicker, while full second storey builds take longer. We’ll give you a realistic timeline during the quote process so you can plan accordingly.

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

Most extensions in Whalan require either Development Approval or a Complying Development Certificate from Blacktown City Council. Some smaller additions might fall under exempt development, but that’s rare for anything meaningful. Our team manages the full approval process for you, including all documentation and liaison with council and certifiers.

Can you extend older brick homes in Whalan?

Absolutely. Most Whalan homes from the 60s, 70s and 80s are solid brick construction on concrete slabs, which makes them great for extending. We assess the existing structure first, but these homes generally have good foundations that can support additional rooms or even a second storey with proper engineering.
