Home Extensions Henley
Built For The Way You Live

Henley is home to a mix of older weatherboard cottages and brick homes from the 1940s through to the 1970s, many sitting on decent sized blocks with good street frontages. The original floor plans in these homes tend to be quite compact with small kitchens and limited living space. An extension makes real sense here, especially when the bones of the home are solid and the location is so convenient to the city and harbour.

We’ve completed extensions throughout Henley and the surrounding pockets of the lower North Shore, working with the character of these older homes while opening them up for modern family life. Whether it’s pushing out the back to create a proper kitchen and living area or adding a second storey to capture water views, we know what works in these streets. Our team handles the full process including council approvals, which can be particular in this area.

Henley attracts families who want that village feel with quick access to the city, and homes here hold their value well. Extending rather than moving means you keep your position in a tightly held suburb while getting the space your family actually needs. A well designed extension will always add more value than it costs, particularly when you’re staying in a location like this.

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!"

How long does a home extension take in Henley?

Most home extensions in Henley 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 unexpected issues we find once we open up the existing structure. We keep you informed throughout the entire build process.

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

Most extensions in Henley require either a Development Application or Complying Development Certificate through Canada Bay Council. The approval process depends on the size of your extension, setbacks from boundaries and heritage considerations in your street. Our team manages the full approval process for you, working with certifiers and planners who know the local requirements.

Can you work with older weatherboard homes in Henley?

Absolutely. Many of the older weatherboard and fibro homes in Henley have great bones and respond well to extensions. We assess the existing structure carefully, make any necessary repairs or reinforcements, and design the addition to complement the original home. The key is matching materials and working with the existing roofline.
