Home Extensions Sandringham
Built For The Way You Live
Sandringham is primarily made up of post war brick homes and weatherboard cottages built from the 1940s through to the 1960s, sitting on modest blocks between 450 and 650 square metres. Many of these original homes feature small bedrooms, dated layouts and limited living space that no longer suits how families actually live today. An extension makes far more sense than selling up, especially when you’re just minutes from the bay and already settled in such a quiet, family friendly pocket.
We’ve completed dozens of extensions throughout Sandringham and the wider St George area, from single storey rear additions to full second storey builds. Our team knows the local housing stock intimately and understands how to work with these older homes, from managing asbestos removal to matching existing brickwork. Every project is tailored to the specific home and how the family actually uses their space.
Sandringham offers genuine value compared to nearby bayside suburbs, which is exactly why families are choosing to extend rather than move. Properties here rarely sit on the market long, and a well designed extension can add $200,000 or more to your home’s value while giving you the extra space you need right now. You get to stay in a suburb where kids can bike to school and the beaches are a five minute drive, without the price tag of Ramsgate Beach or Brighton Le Sands.

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 Sandringham?
Most home extensions in Sandringham take between three to six months from council approval through to final handover. Smaller single room additions can be quicker, while larger second storey builds may take closer to six months. Timeframes depend on the scope of work, weather conditions and any unforeseen issues with the existing structure.
Do I need council approval for a home extension in Sandringham?
Yes, most home extensions in Sandringham require either a Development Application or Complying Development Certificate from Bayside Council. Our team manages the entire approval process on your behalf, from preparing plans to lodging applications and liaising with council. We make sure everything is compliant before any work begins on site.
Can you extend a weatherboard or fibro home in Sandringham?
Absolutely. Many Sandringham homes are original weatherboard or fibro construction, and we extend these all the time. The key is properly assessing the existing structure, managing any asbestos safely if present, and ensuring the new work integrates properly with the old. We’ve got extensive experience working with these older building types across the St George area.
