Home Extensions Gymea Bay
Built For The Way You Live
Gymea Bay is home to a mix of 1960s and 1970s brick homes alongside some original fibro cottages, many sitting on decent sized blocks that back onto bushland or waterways. The majority of homes in the area were built with smaller living spaces and limited outdoor integration, which makes them perfect candidates for extensions. With land at a premium near the water, extending your existing home makes far more sense than trying to upsize in this tightly held suburb.
We’ve completed extensions throughout Gymea Bay and neighbouring suburbs like Gymea, Lilli Pilli and Kirrawee, working with the specific challenges of sloping blocks and bushfire zones common to the area. Our team knows how to work around the local constraints while maximising water glimpses and natural light. From single storey rear additions to complete second storey builds, we handle projects of all sizes across the Sutherland Shire.
Gymea Bay attracts families who value the waterside lifestyle and proximity to good schools without the price tag of harbourside suburbs. Property values have climbed steadily over the past decade, and a well designed extension can add significant equity to your home. Instead of moving away from the bay, boat ramps and national park access you love, extending your current home lets you stay in the area while getting the space your family needs.

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."

FAQS
Got a question?
How much does a home extension cost in Gymea Bay?
A single room addition typically starts from $80,000, while a full ground floor extension starts from $150,000 and a second storey addition from $250,000. These are guide prices only as every project is different depending on your home, block and specific requirements. We provide a free initial consultation and detailed quote for all Gymea Bay projects.
How long does a home extension take in Gymea Bay?
Most extensions take between 3 to 6 months from council approval through to final handover, depending on the size and complexity of your project. A single room addition might take 3 months while a full second storey could take 6 months or more. We provide a realistic timeline during the quoting process and keep you informed at every stage.
Do I need council approval for a home extension in Gymea Bay?
Most home extensions require either Development Approval or a Complying Development Certificate through Sutherland Shire Council. The approval pathway depends on your extension size, location on the block and whether you’re in a bushfire zone. Our team manages the entire approval process for you, including all documentation and liaising with council and certifiers.
Can you extend on sloping blocks in Gymea Bay?
Absolutely. Many homes in Gymea Bay sit on sloping blocks, and we have extensive experience designing and building extensions that work with the natural fall of the land. Whether it’s stepped foundations, undercroft storage or split level designs, we create practical solutions that suit your site. Sloping blocks often provide opportunities for additional space underneath that flat blocks can’t offer.
