Home Extensions Manly Vale
Built For The Way You Live

Manly Vale homes were mostly built between the 1960s and 1980s, with plenty of brick and fibro houses on decent sized blocks around 550 to 700 square metres. These original homes typically have three bedrooms and a single living area, which worked fine decades ago but leaves many families short on space today. The good news is these blocks and the original footprints leave plenty of room to extend without compromising your backyard.

We’ve completed extensions throughout Manly Vale and right across the Northern Beaches, from single storey rear additions to full second storey builds. Most of our projects here involve opening up the back of the house to create modern kitchen and living spaces that connect to the yard, or adding a second level for extra bedrooms and bathrooms. Our team knows the local building requirements and works with Northern Beaches Council regularly to get approvals through efficiently.

Manly Vale offers a great lifestyle close to the beach, schools and shops, which is why property values have climbed steadily over the past decade. Rather than selling and buying bigger in a market where good family homes are expensive and hard to find, extending your current home makes financial sense. A well designed extension not only gives you the space your family needs but adds significant value to your property.

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 Manly Vale?

A single room addition typically starts from $80,000, while a full ground floor extension with kitchen and living areas generally ranges from $150,000 to $250,000. Second storey additions start around $250,000 depending on size and finishes. We provide a free quote and detailed breakdown after assessing your home and discussing your specific needs.

How long does a home extension take in Manly Vale?

Most extensions take between 3 to 6 months from Development Application approval through to final handover, depending on the size and complexity of the project. A straightforward single storey rear addition might take 3 to 4 months, while a full second storey addition usually takes closer to 6 months. We provide a clear timeline during the quoting process and keep you updated throughout.

Do I need council approval for a home extension in Manly Vale?

Most home extensions in Manly Vale require either a Development Application or Complying Development Certificate from Northern Beaches Council. Some smaller additions may qualify for exempt development, but this is rare for meaningful extensions. Our team manages the full approval process including all documentation, liaising with council and responding to any requests.

Can I add a second storey to my Manly Vale home?

Yes, most homes in Manly Vale are suitable for a second storey addition, especially the single level brick homes from the 1960s to 1980s. We assess your existing structure to confirm it can support the additional load, and if strengthening is needed we factor that into the design and quote. Second storey additions are popular here because they maximise space while keeping your backyard intact.
