Home Extensions Gordon
Built For The Way You Live
Gordon homes range from Federation and Californian bungalows through to brick veneer homes from the 1960s and 70s, many sitting on generous 600 to 800 square metre blocks. With the area’s mature tree cover and heritage considerations on certain streets, many original homes were built smaller than what modern families need. An extension allows you to stay in this well connected suburb while creating the extra living space, home office or additional bedrooms your family requires.
We’ve completed dozens of extensions across Gordon and the wider Upper North Shore, from single storey rear additions to double storey builds that transform older homes. Our team understands local council requirements and works with homeowners to design extensions that respect the established character of Gordon streets while meeting modern family needs. Every project is fully managed from concept to completion, with clear communication at each stage.
Gordon’s proximity to the train station, quality schools and parklands makes it one of the more tightly held suburbs on the Upper North Shore. Property values here have remained strong, and families who secure a home often want to stay long term rather than upsize elsewhere. A well designed extension not only gives you the space you need now but adds significant value to your property, typically returning well above the construction cost when you eventually 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."

"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!"

The timeline depends on the scope of work, weather conditions and any specific council requirements. We provide a detailed schedule at the start of every project so you know exactly what to expect.
Do I need council approval for a home extension in Gordon?
Most extensions in Gordon require either a Development Application or Complying Development Certificate through Ku-ring-gai Council. Some smaller additions may qualify for exempt development, but this depends on your property’s zoning and existing structures. We manage the full approval process and work with experienced consultants who know the local council requirements well.
Can I extend a Federation home in Gordon?
Absolutely. Many Federation and Californian bungalow homes in Gordon are ideal for extensions, particularly rear additions that preserve the original street facade. We design extensions that complement the existing architecture while providing modern, functional living spaces. Our team works within any heritage guidelines that apply to your property.
