Home Extensions Greenhills Beach
Built For The Way You Live
Greenhills Beach is home to a mix of original fibro beach shacks and brick homes from the 1960s and 70s, most sitting on decent sized blocks with established gardens. Many homes here have good bones but lack the open plan living areas and extra bedrooms modern families need. An extension often makes far more sense than selling up and leaving this quiet beachside pocket.
We’ve completed extensions throughout Greenhills Beach and neighbouring Cronulla, working with the local housing stock and council requirements. Our team knows how to design additions that respect the relaxed coastal feel while giving you the space you actually need. From second storeys capturing water views to ground floor living extensions opening to the backyard, we build what works for your home and your family.
With the beach at your doorstep and the national park next door, Greenhills Beach offers a lifestyle that’s hard to beat in Sydney. Property here holds its value well, and a well designed extension can significantly increase what your home is worth. Adding liveable space means you get to stay in this tightly held community without compromise.

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!"

Got a question?
How much does a home extension cost in Greenhills Beach?
A single room addition typically starts from $80,000, while a full ground floor extension starts from $150,000. Second storey additions generally start from $250,000 depending on design and finishes. We provide a detailed free quote after assessing your home and discussing what you want to achieve.
How long does a home extension take in Greenhills Beach?
Most extensions take between 3 to 6 months from council approval through to final handover, depending on the scope and complexity of your project. The approval process itself can add a few months, but we manage that entire timeline for you. We’ll give you a realistic timeframe once we understand what you’re planning.
Do I need council approval for a home extension in Greenhills Beach?
Most extensions require either a Development Application or Complying Development Certificate through Sutherland Shire Council. Some smaller additions may qualify for an exemption, but that’s rare for meaningful extensions. We handle the full approval process including plans, documentation and council liaison so you don’t have to worry about it.
Can I add a second storey to capture water views?
Many homes in Greenhills Beach can benefit from a second storey addition to capture views over the beach and Port Hacking. We’ll assess your existing structure and design an addition that maximises those views while meeting council height limits. It’s often the best way to add space and value in this location.
