Home Extensions Greenwich
Built For The Way You Live
Greenwich is filled with beautiful period homes from the 1920s and 1930s, many sitting on decent sized blocks with water glimpses or views across to the city. These older homes often have compact living areas, small kitchens and limited storage, making them perfect candidates for a well planned extension. With block sizes typically between 500 and 800 square metres, there’s genuine opportunity to add space without compromising your garden.
We’ve worked on plenty of extensions throughout Greenwich and nearby Lane Cove, Wollstonecraft and Longueville, so we understand the character of these older North Shore homes. Our team knows how to match existing brickwork, respect the original architecture and deliver additions that feel like they’ve always been there. Every project is managed by licensed builders who live and work on the North Shore.
Greenwich families value their proximity to the city, the established community feel and the quality local schools. With median house prices well over $3 million, extending your current home makes far more sense than buying and moving, especially when you’re already in a location you love. A quality extension can add 15 to 20 percent to your property value while giving you the extra space your family actually needs.

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."
Amanda
"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!"
Angela
"Fantastic! Monstructions did an amazing job on my home extension, all the boys that worked on my house were professional and polite, and their quality of work was second to none. From drawings to completion it was a breeze working with them. They were easy to work with and extremely efficient and professional. Thank you for all the hard work and effort, I will recommend you to everyone I know."

FAQS
Got a question?
How much does a home extension cost in Greenwich?
A single room addition in Greenwich typically starts from $80,000, while a full ground floor extension usually ranges from $150,000 depending on size and finishes. Second storey additions start from $250,000 due to structural requirements and site access considerations. We provide a free detailed quote after assessing your home and understanding exactly what you need.
How long does a home extension take in Greenwich?
Most extensions in Greenwich take between three to six months from council approval through to final handover, depending on the scope of work. Ground floor additions are typically faster, while second storey projects require more time for structural work and weatherproofing. We’ll give you a realistic timeline during your initial consultation based on your specific project.
Do I need council approval for a home extension in Greenwich?
Most home extensions in Greenwich require either a Development Application or Complying Development Certificate through Lane Cove Council. The approval pathway depends on your extension size, setbacks and whether your property has any heritage considerations. Our team manages the entire approval process for you, working with experienced local certifiers and architects who know the council requirements.
Can you match the original brickwork on older Greenwich homes?
Absolutely, we’ve matched plenty of original face brick and rendered finishes on period Greenwich homes from the interwar era. We source matching bricks from salvage yards when possible or work with suppliers who can closely replicate the original colour and texture. The goal is always an extension that looks like it’s part of the original home, not an obvious addition.
