Home Extensions South Coogee
Built For The Way You Live
South Coogee is home to a mix of post war brick homes, 1960s and 70s cottages, and some newer builds, mostly sitting on modest blocks between 400 and 600 square metres. Many original homes were built for different times, with small kitchens, limited living space and no connection to outdoor areas. An extension is often the smartest way to create the space your family needs without leaving this quiet coastal pocket.
We’ve completed extensions throughout South Coogee and neighbouring suburbs like Coogee and Maroubra, adding second storeys to capture ocean glimpses, ground floor rear extensions for open plan living, and side additions where block width allows. Most projects involve opening up the back of the house to create better flow to the yard and more natural light. Our team knows the local building requirements and works with certifiers familiar with Randwick Council’s planning controls.
South Coogee sits in one of Sydney’s tightest property markets, where buying bigger means spending well over two million for anything decent. A well planned extension can add $300,000 to $500,000 in property value while costing considerably less to build. Families here want to stay close to the beaches, parks and schools, making an extension far more appealing than uprooting to find more space elsewhere.

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."
Amanda
"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!"
Angela
"Fantastic! Monstructions did an amazing job on my home extension, all the boys that worked on my house were professional and polite, and their quality of work was second to none. From drawings to completion it was a breeze working with them. They were easy to work with and extremely efficient and professional. Thank you for all the hard work and effort, I will recommend you to everyone I know."

Our team manages the full approval process including plans, reports and council liaison so you don’t have to deal with the paperwork.
Can I add a second storey to capture ocean views?
Many South Coogee homes can add a second storey to capture ocean or coastline views, though height limits and planning controls vary by street and block. We’ll assess your property’s potential during our site visit and advise whether a second storey is feasible.
