Home Extensions Manly
Built For The Way You Live
Manly homes range from original 1920s bungalows and 1950s fibro cottages on compact blocks through to larger properties backing onto bushland reserves. Many homes sit on blocks between 400 and 600 square metres, with some heritage considerations near the corso and beachfront areas. An extension makes far more sense than moving when you’re already in one of Sydney’s most desirable beachside locations.
We’ve completed extensions across Manly and neighbouring suburbs like Fairlight and Balgowlah, working with the local terrain and coastal conditions. Our team understands building near the ocean, from salt exposure considerations to making the most of water views where they exist. Every project is designed to suit the specific home and how the family actually lives.
Manly homeowners value the beach lifestyle, village feel and proximity to the city without the crowds. Property prices reflect this demand, which means extending your current home delivers serious value compared to buying something larger in the same area. Adding a second storey or ground floor extension lets you stay in the community while getting the space your family needs.

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."

FAQS
Got a question?
How much does a home extension cost in Manly?
A single room addition typically starts from $80,000, while a full ground floor extension starts from $150,000. Second storey additions generally start from $250,000 depending on scope and finishes. We provide a free detailed quote after assessing your home and understanding what you need.
How long does a home extension take in Manly?
Most home extensions take between 3 to 6 months from council approval through to final handover. The timeline depends on the scope of work, weather conditions and any site access challenges. We provide a clear schedule at the start and keep you informed throughout the build.
Do I need council approval for a home extension in Manly?
Most extensions in Manly require either a Development Application or Complying Development Certificate through Northern Beaches Council. Some areas have heritage overlays or other planning considerations that affect approval. We manage the entire approval process for you, working with certifiers and planners who know the local requirements.
Can I add a second storey to my Manly home?
Many Manly homes are suitable for a second storey addition, particularly the older single level bungalows and cottages common throughout the suburb. Height limits and view sharing provisions apply in some areas, and we assess the existing structure to ensure it can support the additional load. A second storey is often the best way to gain space and capture water views on a compact block.
