Home Extensions Coogee
Built For The Way You Live

Coogee’s housing stock is mostly federation and interwar homes on compact blocks, with many properties sitting on 300 to 450 square metre lots. These older homes were built for a different era, with smaller kitchens, limited storage and fewer living spaces than modern families need. An extension lets you stay in this beachside suburb without compromising on the space your family needs.

We’ve completed extensions across Coogee and neighbouring areas like Randwick and Clovelly, working within the constraints of smaller blocks and heritage considerations. Our team understands the local council requirements and how to maximise space on tighter sites. Whether it’s a rear addition, second storey or full renovation with extension, we make the process straightforward from concept to completion.

Living close to the beach in Coogee means you’re paying a premium for location, so moving further out to get more space doesn’t appeal to most families here. Property values remain strong, and a well designed extension can add significant value while letting you stay in the area you love. The local schools, beach access and community feel make it worth investing in your existing home rather than uprooting the family.

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."

Randwick

"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 Coogee?

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

Most extensions in Coogee require either a Development Application or Complying Development Certificate from Randwick Council. The approval pathway depends on the size of your extension and whether your property has any heritage considerations. We manage the full approval process on your behalf, working with town planners and certifiers to get your extension approved.

Can you build up on federation homes in Coogee?

Yes, many federation homes in Coogee are suitable for second storey additions, though each property needs individual assessment. We check the existing structure, foundation capacity and council height limits before proceeding. Adding a second level is often the best way to gain space on Coogee’s smaller blocks without losing your backyard.
