Home Extensions Port Hacking
Built For The Way You Live
Port Hacking homes are mostly post war brick and weatherboard properties from the 1950s to 1970s, with some newer builds scattered throughout. Most blocks range from 550 to 800 square metres, giving you plenty of room to extend without losing your backyard. Many original homes have smaller living areas and dated layouts that just don’t work for modern family life.
We’ve completed extensions across Port Hacking and the surrounding waterfront suburbs, working with everything from original fibro cottages to brick homes that need a complete transformation. Our team knows the local council requirements and what works on these blocks. Whether you’re after a second storey to capture water views or a ground floor extension for more living space, we handle the entire process from concept to completion.
The waterfront location and proximity to the Royal National Park make Port Hacking tightly held, with families wanting to stay put rather than move. Extending your existing home lets you create the space you need while keeping your position in this quiet, family friendly area. A well designed extension can add significant value, especially when it opens up living areas or adds that extra bedroom and bathroom growing families need.

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 Port Hacking?
A single room addition typically starts from $80,000, while a full ground floor extension generally ranges from $150,000 upwards depending on size and finishes. Second storey additions start around $250,000. We provide a free detailed quote after assessing your property and understanding exactly what you want to achieve.
How long does a home extension take in Port Hacking?
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 DA approval process with Sutherland Shire Council typically adds another 8 to 12 weeks before construction begins. We’ll give you a realistic timeline during your initial consultation.
Do I need council approval for a home extension in Port Hacking?
Most home extensions require either Development Approval or a Complying Development Certificate from Sutherland Shire Council. Some smaller additions may fall under exempt development, but this depends on your specific property and what you’re planning. We handle the full approval process for you, including all documentation and liaison with council and certifiers.
Can I add a second storey to capture water views?
Many Port Hacking properties have the potential for second storey additions to capture glimpses or full views of the water. We’ll assess your block’s orientation, height limits and setback requirements during the initial site visit. A second level often makes more sense than extending out, especially on the smaller blocks closer to the waterfront.
