Home Extensions Sylvania
Built For The Way You Live
Sylvania’s housing stock is mostly solid brick homes from the 1960s and 70s, sitting on generous blocks between 550sqm and 700sqm. Many of these homes have original layouts with smaller bedrooms, dated bathrooms and limited living areas that no longer suit modern family life. With land this size increasingly rare across Sydney, extending your existing home makes far more sense than selling and starting over.
We’ve completed dozens of extensions across Sylvania and neighbouring suburbs like Gymea and Miranda, adding second storeys, rear extensions and granny flats to these solid post war homes. The typical Sylvania home has great bones and responds well to thoughtful additions that respect the original build while creating the space families actually need. Our local knowledge means we understand the council requirements, typical site conditions and what works best for homes in this area.
Sylvania attracts families who want quality schools, parks and a strong community feel without the price tag of beachside suburbs. Property values here have climbed steadily, and a well designed extension can add $200,000 to $300,000 to your home’s value while giving you the lifestyle you want right now. Instead of uprooting to find more space, most Sylvania families find extending their current home lets them stay in the area they love.

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 Sylvania?
Most home extensions in Sylvania take between 3 to 6 months from council approval through to final handover. The timeline depends on the size and complexity of your project, weather conditions and any unexpected site issues. We’ll give you a realistic timeframe upfront and keep you informed throughout the entire build.
Do I need council approval for a home extension in Sylvania?
Yes, most extensions in Sylvania require either a Development Application or Complying Development Certificate from Sutherland Shire Council. The approval process typically takes 6 to 12 weeks depending on your project scope. Our team manages the full approval process including plans, engineering, surveys and all council submissions so you don’t have to deal with the paperwork.
Can I add a second storey to my Sylvania home?
Most single storey brick homes in Sylvania are structurally suitable for a second storey addition, though each property needs individual assessment. We arrange structural engineering reports to confirm your existing footings and walls can support the additional load. Second storeys are popular in Sylvania because they maximise your existing land without losing yard space.
