Home Extensions Gregory Hills
Built For The Way You Live
Gregory Hills is one of the newer growth areas in Sydney’s southwest, with most homes built from the early 2010s onwards on relatively compact blocks between 300 and 450 square metres. While the estates were designed for modern family living, many homeowners quickly find they need more space as kids grow or work from home becomes permanent. An extension makes far more sense than selling and dealing with stamp duty in this tight property market.
We’ve completed dozens of extensions throughout Gregory Hills and nearby suburbs like Oran Park and Gledswood Hills. The work ranges from simple ground floor rear additions that open up the living areas, to second storey builds that add three or four bedrooms without losing yard space. Our team knows the local building codes and works with council regularly to get approvals through efficiently.
Gregory Hills has become incredibly popular with young families thanks to the schools, parks and shopping at the village centre. Property values have climbed steadily since the suburb was established, and a well planned extension can add $150,000 to $250,000 to your home’s value. Rather than upsizing to a bigger mortgage in an outer suburb with a longer commute, most families find extending their current home gives them the space they need while staying in the community they love.

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 much does a home extension cost in Gregory Hills?

How long does a home extension take in Gregory Hills?
Most home extensions take between 3 to 6 months from council approval through to final handover, depending on the scope of work. A simple single room addition might be completed in 3 months, while a large second storey could take 6 months or more. We provide a detailed construction schedule as part of your contract so you know exactly what to expect.
Do I need council approval for a home extension in Gregory Hills?
Most extensions in Gregory Hills require either Development Approval or a Complying Development Certificate from Camden Council. Some very minor works might qualify for exempt development, but anything adding habitable space generally needs approval. Our team manages the entire approval process including plans, surveys and liaising with council on your behalf.
Can you add a second storey to newer Gregory Hills homes?
Absolutely, and we do this regularly in Gregory Hills and surrounding estates. Most homes built from 2010 onwards have decent foundations, but we always arrange a structural engineer’s inspection first to confirm the existing slab and frame can support the additional load. In most cases the structure is fine and we can proceed with a straightforward second storey addition.
