Home Extensions Balgowlah Heights
Built For The Way You Live

Balgowlah Heights features predominantly brick and fibro homes built through the 1960s and 70s, many on elevated blocks with harbour or bushland views. The original footprints were modest, with smaller bedrooms and basic bathrooms that no longer suit modern family life. Extending makes far more sense than moving, especially when you’ve got established gardens and those Northern Beaches views locked in.

We’ve completed plenty of extensions throughout Balgowlah Heights and nearby suburbs like Fairlight and Allambie Heights, adding ground floor living areas, master suites and second storeys that maximise the outlook. Most homes here have good bones but need better flow between indoor and outdoor spaces. Our local knowledge means we understand the council requirements and what works on these elevated sites.

Families stay in Balgowlah Heights for the schools, the village feel and quick access to both Manly and the city. Property values here have climbed steadily, and a well planned extension can add serious equity while giving you the extra space your family actually needs. With blocks this well located, making the most of what you’ve got is a smart move.

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!"

FAQS

Got a question?

How much does a home extension cost in Balgowlah Heights?

A single room addition typically starts from $80,000, while a full ground floor extension usually begins around $150,000. Second storey additions start from $250,000 depending on design and finishes. We provide a free quote and work with your budget to deliver the best outcome for your home.

How long does a home extension take in Balgowlah Heights?

Most home extensions take between three to six months from council approval through to final handover. The timeline depends on the size and complexity of your project. We’ll give you a clear schedule upfront and keep you informed at every stage of the build.

Do I need council approval for a home extension in Balgowlah Heights?

Most extensions require either Development Application or Complying Development Certificate approval through Northern Beaches Council. The approval pathway depends on your property, the extent of works and local planning controls. We handle the full approval process for you, working with certifiers and ensuring everything meets code.

Can you extend upwards on sloping Balgowlah Heights blocks?

Absolutely. Many Balgowlah Heights properties sit on sloping or elevated blocks, which actually creates great opportunities for split level extensions or additional storeys. We assess the site conditions, existing foundations and council height limits to design an extension that works with your block. The views from a second storey addition up here are often worth the investment alone.
