Home Extensions Willoughby East
Built For The Way You Live

Willoughby East is dominated by solid brick homes from the 1960s and 70s, with many original Californian bungalows still standing on generous blocks. These homes typically sit on 600 to 800 square metre blocks, giving plenty of room to extend without losing valuable garden space. The original floor plans often feel cramped by today’s standards, making them perfect candidates for a well designed extension.

We’ve completed dozens of extensions throughout Willoughby East and the surrounding North Shore suburbs, working with families who need more space but want to stay in the area. Most of our projects involve opening up the rear of the home to create modern kitchen and living areas that flow to the backyard. We also regularly add second storeys to take advantage of district views while maximising the existing footprint.

Willoughby East sits in a tightly held pocket where families rarely leave once they’re established. With North Shore Grammar and Willoughby Girls High nearby, homeowners are choosing to extend rather than upsize into a more expensive property. A quality extension can add $300,000 to $500,000 in value while giving you the home you actually want to live in.

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 Willoughby East?

A single room addition typically starts from $80,000, while a full ground floor extension usually begins around $150,000. Second storey additions generally start from $250,000 depending on size and finishes. We provide a free quote after an on site consultation to assess your home and discuss what you’re looking to achieve.

How long does a home extension take in Willoughby East?

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, with second storey additions typically taking longer than ground floor extensions. We’ll give you a clear construction timeline before any work begins.

Do I need council approval for a home extension in Willoughby East?

Most home extensions in Willoughby East require either a Development Application or Complying Development Certificate through Willoughby Council. Some smaller additions may qualify as exempt development, but this depends on size, setbacks and other planning controls. We manage the entire approval process for you, including dealing with council and certifiers.

Can I extend a brick home in Willoughby East?

Absolutely. The majority of homes in Willoughby East are brick construction from the 60s and 70s, and we extend them regularly. We carefully match brickwork where needed or use contrasting materials to create a modern addition that complements the original home. Our structural engineers assess every project to ensure the existing foundations can support the new work.
