Home Extensions Northbridge
Built For The Way You Live

Northbridge homes are predominantly post war brick and tile builds on relatively modest blocks, many around 550 to 700 square metres. Most of these homes were built in the 1950s and 1960s with smaller bedrooms and limited living space by today’s standards. Rather than moving away from excellent schools and public transport, more families are choosing to extend and renovate their existing homes.

We’ve completed extensions throughout Northbridge and neighbouring suburbs like Cammeray and Willoughby, working with the typical constraints of sloping blocks and setback requirements. Our projects range from single storey rear additions that open up living spaces to second storey builds that add much needed bedrooms and bathrooms. Each extension is designed to work with the existing home and make the most of the site.

Northbridge offers excellent access to the city via bus and harbour, plus quality local schools that attract young families. Property prices in the area reflect this desirability, which makes extending your current home a smart investment compared to buying a larger property in the same postcode. A well designed extension not only gives you the space you need but also adds considerable value to your home.

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 Northbridge?

A single room addition typically starts from $80,000, while a full ground floor extension begins around $150,000. Second storey additions generally start from $250,000 depending on size and finishes. We provide a free detailed quote after assessing your home and discussing your requirements.

How long does a home extension take in Northbridge?

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 specific challenges. We provide a clear construction schedule at the start of every project so you know what to expect.

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

Most extensions require either a Development Application or Complying Development Certificate from Willoughby Council. We manage the entire approval process on your behalf, including all drawings, documentation and council liaison. Our team knows the local planning requirements and works to get your approval as smoothly as possible.

Can you build up on sloping blocks in Northbridge?

Yes, many Northbridge properties sit on sloping blocks which can actually work in your favour for second storey additions. The natural fall often means less visible impact from the street and better views from upper levels. We assess each site individually and design extensions that work with the existing terrain and meet all council requirements.
