Home Extensions Cammeray
Built For The Way You Live
Cammeray is filled with post war homes from the 1940s and 1950s, mostly sitting on 600 to 800 square metre blocks with generous rear yards. Many of these homes have original footprints that no longer suit modern family life, with small kitchens, few bathrooms and limited living space. An extension makes far more sense than moving, especially given the location and established feel of the suburb.
We’ve completed dozens of extensions in Cammeray and nearby suburbs like Northbridge and Naremburn, working with the common home styles in the area. Most projects involve extending out the back to create open plan living areas, adding a second bathroom, or building up to capture views toward the harbour. Our team knows the local council requirements and how to design additions that complement the original home.
Cammeray attracts families who want access to good schools, parks and quick commutes without paying harbour side prices. Properties here hold their value well, and a thoughtfully designed extension can add $200,000 to $400,000 to your home’s worth. With the median house price sitting above $2.5 million, extending your current home is often the smartest financial move compared to buying something bigger in the same area.

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 Cammeray?
Most home extensions take between 3 to 6 months from council approval through to final handover, depending on the scope of work. The council approval process itself usually takes 8 to 12 weeks for a standard DA in North Sydney Council. We’ll give you a clear timeline during the quoting process so you know exactly what to expect.
Do I need council approval for a home extension in Cammeray?
Most extensions require either a Development Application or Complying Development Certificate from North Sydney Council. Some minor additions may fall under exempt development, but this is rare for anything substantial. We manage the entire approval process for you, including plans, documentation and submissions.
Can I build up on my Cammeray home?
Many Cammeray homes are suited to a second storey addition, especially those on the higher parts of the suburb where you can capture harbour glimpses or city views. We assess your existing structure during the initial consultation to determine if your foundations and framing can support an upper level. If not, we can recommend alternatives like extending out the back or reconfiguring your existing layout.
