Home Extensions Glenorie
Built For The Way You Live

Glenorie homes sit on generous acreage blocks, many with original dwellings from the 1970s and 1980s that were built modestly compared to today’s family needs. These larger rural blocks give homeowners excellent flexibility to extend without sacrificing yard space. Adding a proper living area, extra bedrooms or a parents retreat makes far more sense than moving when you’ve already got established land and privacy.

We’ve completed extensions across Glenorie and surrounding areas like Dural and Kenthurst, working with the rural residential character that defines this part of the Hills. Our projects range from single storey additions that blend with existing rooflines to full rear extensions that open up to the property’s natural surrounds. Each build is tailored to the home’s existing footprint and the family’s practical requirements.

Families choose Glenorie for space, quiet and the semi rural lifestyle that’s still within reach of the city. Rather than downsizing or relocating closer to town, extending your current home lets you keep the lifestyle while gaining the space your family has outgrown. A well planned extension protects your investment and makes your property work harder without losing what drew you here in the first place.

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!"

FAQS

Got a question?

How much does a home extension cost in Glenorie?

How long does a home extension take in Glenorie?

Most home extensions take between 3 to 6 months from council approval through to final handover, depending on the scope and complexity of the build. Weather can occasionally affect timelines on rural properties, but we keep you updated throughout. We provide a clear schedule once plans are finalised and approvals are in place.

Do I need council approval for a home extension in Glenorie?

Most extensions in Glenorie require either a Development Application or Complying Development Certificate through The Hills Shire Council. We manage the full approval process on your behalf, preparing plans and lodging all necessary documentation. Our experience with local council requirements means fewer delays and a smoother approval process.

Can I extend on a sloping acreage block?

Absolutely. Many Glenorie properties have natural slope and contour, which we work with during the design phase. We assess drainage, access and the best way to integrate the extension with your existing home and land. Sloping sites can actually create opportunities for interesting designs that make the most of views and natural light.
