Home Extensions Edgecliff
Built For The Way You Live
Edgecliff properties range from the older apartment blocks along New South Head Road to the Edwardian and Federation era homes on the quieter streets backing onto Rushcutters Bay Park. Many of these homes sit on smaller blocks with limited room to build out, making second storey additions or clever internal reconfigurations the best path forward. The tight streetscape and proximity to neighbours means working with an experienced builder who understands local requirements is essential.
We’ve completed extensions throughout Edgecliff and surrounding suburbs like Double Bay and Darling Point where space comes at a premium. Our team knows how to maximise every square metre without compromising the character of your existing home. Whether you need an extra bedroom upstairs or want to open up the ground floor to capture harbour glimpses, we’ll work within your site’s constraints to deliver a functional, well built extension.
Edgecliff’s proximity to the city, shopping at Double Bay and waterfront parks makes it an incredibly convenient place to live. Property values here reflect that location, so extending your current home often makes better financial sense than buying elsewhere in the area. A well executed extension lets you stay in the neighbourhood while gaining the space your family needs, whether that’s a home office, extra living room or an additional bathroom.

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!"

We’ll give you a realistic construction schedule once we’ve finalised the design and understand the full extent of works required.
Do I need council approval for a home extension in Edgecliff?
Most extensions in Edgecliff require either a Development Application or Complying Development Certificate through Woollahra Council. The approval path depends on your property’s zoning, heritage considerations and the size of your proposed extension. We manage the full approval process including engaging architects, engineers and liaising with council on your behalf.
Can you extend a home on a steep Edgecliff block?
Yes, we regularly work on sloping sites throughout Edgecliff and the Eastern Suburbs. Steep blocks require careful engineering and often benefit from building upwards rather than outwards. Our team will assess your site’s constraints and recommend the most practical and cost effective extension solution for your property.
