Home Extensions Sutherland
Built For The Way You Live

Sutherland is dominated by solid brick homes built between the 1960s and 1980s, with many sitting on generous 600 to 800 square metre blocks. These properties were built for a different era, often featuring choppy floor plans, small kitchens and limited connection to the backyard. An extension lets you reconfigure the layout and create the modern family spaces these homes lack without leaving the area.

We’ve completed dozens of extensions across Sutherland and nearby suburbs like Como, Jannali and Woronora. From ground floor rear additions that open up the kitchen and living areas to full second storey builds that double the floor space, we know how to work with the typical brick construction found throughout the Shire. Every project is managed by our licensed builders from concept right through to completion.

Sutherland offers great schools, quick access to the train station and a strong community feel that keeps families in the area long term. With median house prices sitting over $1.5 million, extending your current home makes more financial sense than selling and buying elsewhere. A well planned extension can add $200,000 or more 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 Sutherland?

A single room addition typically starts from around $80,000, while a full ground floor extension ranges from $150,000 upwards depending on size and finishes. Second storey additions generally start from $250,000 including structural work and internal stairs. We provide a free quote and detailed scope of works for every Sutherland project.

How long does a home extension take in Sutherland?

Most extensions take between three to six months from council approval through to final handover, depending on the size and complexity of the build. Council approval times vary but typically add another two to three months to the overall timeline. We provide a detailed construction schedule at the start of every project so you know exactly what to expect.

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

The majority of extensions require either Development Approval or a Complying Development Certificate from Sutherland Shire Council. Some very minor additions may qualify for exempt development, but this is rare for anything involving habitable space. Our team manages the entire approval process including plans, surveys and submissions.

Can you extend older brick homes in Sutherland?

Absolutely. Most of the homes we extend in Sutherland are original brick builds from the 60s, 70s and 80s. We assess the existing structure, match or complement the brickwork and ensure the new extension integrates properly with the old construction. These older homes are perfect candidates for modern rear additions that completely transform how they function.
