Home Extensions East Killara
Built For The Way You Live
East Killara homes are predominantly solid brick and sandstone houses from the 1950s through to the 1980s, sitting on generous blocks that typically range from 800 to 1200 square metres. Many of these original homes feature compartmentalised layouts with smaller living areas that no longer suit how modern families actually live. The substantial land size and quality construction make these properties ideal candidates for extension rather than demolition and rebuild.
We’ve completed dozens of extensions throughout East Killara and neighbouring Killara, working with the area’s architectural controls while creating functional, family friendly spaces. Our team understands the specific requirements of Ku-ring-gai Council and how to design extensions that complement the leafy character of the suburb. From rear ground floor additions that open to the garden through to second storey expansions capturing district views, we handle every project with proper attention to detail.
East Killara attracts families who value the quality schools, large blocks and quiet streets lined with established gardens. Property values here remain strong, and a well designed extension typically adds more value than it costs while letting you stay in a location you’ve chosen carefully. Rather than selling and paying stamp duty elsewhere, extending your existing home lets you create exactly what your family needs while keeping the kids in their schools and your established community connections intact.

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!"

How long does a home extension take in East Killara?
Most home extensions in East Killara take between three and six months from development approval through to final handover, depending on the scope and complexity of the work. Ku-ring-gai Council DA approval typically adds another two to three months to the overall timeline. We provide a clear construction schedule upfront and keep you informed throughout every stage of the build.
Do I need council approval for a home extension in East Killara?
Most extensions in East Killara require either a Development Application or Complying Development Certificate from Ku-ring-gai Council, as very few additions fall within exempt development provisions. Our team manages the entire approval process including architectural plans, engineering documentation and all council submissions. We know the local planning controls well and design extensions that meet requirements while maximising your available space.
Can I add a second storey to my East Killara home?
Many single storey homes in East Killara are structurally suitable for a second storey addition, particularly the solid brick and sandstone houses from the 1950s and 1960s. We conduct a full structural assessment to determine what foundation and framing work is needed, then design an upper level that respects neighbourhood character while capturing those sought after leafy outlooks. The investment typically delivers excellent returns given the premium East Killara location and quality school zones.
