Home Extensions Sans Souci
Built For The Way You Live
Sans Souci is home to predominantly post war brick homes and fibro cottages built through the 1950s and 60s on generous blocks between 550 and 700 square metres. Many of these original homes feature compact floor plans with small kitchens, separate living areas and limited bathrooms that no longer suit how modern families actually live. An extension is often the smartest way to create the extra space you need without leaving this waterside suburb.
We’ve completed extensions throughout Sans Souci and neighbouring suburbs like Ramsgate Beach and Kogarah Bay, working with the area’s typical housing stock and council requirements. Our team knows how to design additions that respect the character of your street while delivering the functional spaces your family needs. From rear extensions that open onto the backyard to second storey additions that capture water glimpses, we build what works for your home and your block.
With its proximity to Botany Bay and strong community feel, Sans Souci continues to attract families who want to stay in the area long term. Property values here have climbed steadily, and a well planned extension delivers genuine return on investment while letting you keep the location and lifestyle you love. Adding a modern kitchen, extra bedroom or upstairs living space means you get the home you need without the stress and cost of moving.

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!"

Do I need council approval for a home extension in Sans Souci?
Most extensions require either a Development Application or Complying Development Certificate through Georges River Council. The approval pathway depends on your specific plans, setbacks and site conditions. Our team manages the full approval process for you, working with certifiers and planners to get your extension approved.
Can I add a second storey to my Sans Souci home?
Yes, many post war brick homes in Sans Souci are structurally suitable for a second storey addition, though some require foundation and wall strengthening. We assess your existing structure during the design phase and include any required structural upgrades in your quote. Adding a second level is a great way to capture bay views while keeping your backyard intact.
