Home Extensions Bonnyrigg Heights
Built For The Way You Live
Bonnyrigg Heights is dominated by brick homes built from the late 1980s through to the early 2000s, sitting on decent sized blocks that typically range from 500 to 700 square metres. Many of these homes were built with basic three or four bedroom layouts that no longer suit growing families or modern living requirements. The good block sizes and solid construction make these properties perfect candidates for extension work rather than the expense and disruption of moving.
We’ve completed numerous extensions throughout Bonnyrigg Heights and neighbouring suburbs like Edensor Park and Bonnyrigg, adding second storeys, rear extensions and granny flats to homes that needed more space. Our team knows the local building requirements and works regularly with Fairfield Council on development applications. Every project is handled by our licensed builders who live and work across Western Sydney.
Bonnyrigg Heights attracts families who want good schools, parks and easy access to the M7 and M4 motorways without paying inner west prices. Property values here have climbed steadily over the past decade, and a well designed extension can add significant value while giving your family the extra space you need. Most homeowners find extending their current home makes more financial sense than selling and buying bigger in the same area.

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."

How long does a home extension take in Bonnyrigg Heights?

A single room addition might be completed in 10 to 12 weeks, while a full second storey addition typically takes 5 to 6 months. We provide a clear timeline during the quoting stage and keep you updated throughout the entire build.
Do I need council approval for a home extension in Bonnyrigg Heights?
Most extensions in Bonnyrigg Heights require either a Development Application or Complying Development Certificate through Fairfield Council, depending on the size and type of work. Some minor alterations may qualify as exempt development, but this is rare for actual extensions. Our team manages the full approval process including all documentation, plans and liaison with council or certifiers.
Can I add a second storey to my Bonnyrigg Heights home?
Yes, most homes in Bonnyrigg Heights are suitable for second storey additions as they were built with solid brick or concrete block construction from the late 1980s onwards. We complete a structural assessment to confirm your existing footings and walls can support the additional load, and design the upper level to complement your home’s existing style. Second storey additions are popular here as they maximise your floor space without losing valuable backyard area.
