Home Extensions Kyle Bay
Built For The Way You Live
Kyle Bay homes are largely post-war brick builds from the 1950s and 60s, sitting on generous blocks between 550 and 800 square metres. These solid older homes have great bones but often feature closed-off floor plans, small kitchens and limited connection to backyards. An extension allows you to update the layout, add another bedroom or bathroom, and create the light-filled open plan living that families need today.
We’ve built ground floor rear extensions, second storey additions and full home renovations throughout Kyle Bay and across the Kogarah Bay waterfront area. Our team understands the local building controls, slope challenges and how to work with the character of older St George homes. Every project is managed by our licensed builders who coordinate trades, handle approvals and keep everything running smoothly from start to finish.
Kyle Bay offers a quiet, family-friendly lifestyle close to the water with good schools nearby and easy access to the city. Property values here continue to climb as buyers look for affordable St George locations with space and character. A well-designed extension not only improves your daily living but adds serious resale value, often returning more than the build cost when it’s time to sell.

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 long does a home extension take in Kyle Bay?

Do I need council approval for a home extension in Kyle Bay?
Most extensions in Kyle Bay require either Development Approval or a Complying Development Certificate from Bayside Council. There are some exemptions for very minor work, but anything structural or that changes the building footprint will need approval. Our team manages the entire approval process including plans, documentation and council liaison so you don’t have to.
Can you extend on a sloping block in Kyle Bay?
Yes, many Kyle Bay properties have sloping rear yards that drop away towards the waterways. We regularly design extensions that work with the slope, using split levels or elevated decks to maximise usable space. Our team assesses the site early to provide cost-effective solutions that suit the natural contours of your block.
