Home Extensions Surry Hills
Built For The Way You Live
Surry Hills is packed with terraces and Victorian workers cottages built from the 1880s through to the early 1900s, most sitting on tight blocks between 100 and 200 square metres. These homes were built for smaller families with fewer possessions, which is why so many owners today find themselves running out of room. An extension is often the smartest way to gain the extra bedroom, bathroom or living space you need without leaving the area.
We’ve completed extensions across Surry Hills and nearby suburbs like Redfern and Chippendale, working with everything from single fronted terraces to corner blocks with laneway access. Whether it’s a rear addition that opens to a courtyard, a second storey over the back rooms, or a full renovation with structural changes, we understand the challenges and opportunities these older homes present. Our team knows how to work within heritage considerations and council requirements specific to this part of Sydney.
Surry Hills has become one of the most tightly held postcodes in Sydney, with families wanting to stay close to the city, parks like Prince Alfred and the cafes along Crown Street. Property values here mean that investing in a well designed extension makes financial sense, often adding more value than the build cost. A quality extension lets you stay in the neighbourhood you love while getting the 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."

Council approval times in the City of Sydney can vary, usually taking 8 to 12 weeks. We keep you informed at every stage and manage the full timeline from design through to completion.
Do I need council approval for a home extension in Surry Hills?
Most extensions require either a Development Application or Complying Development Certificate from the City of Sydney Council. Some smaller works may qualify for exempt development, but this depends on your specific property and what you’re planning. We manage the full approval process including plans, submissions and liaising with council on your behalf.
Can you extend a narrow terrace in Surry Hills?
Absolutely. We’ve extended dozens of narrow terraces across Surry Hills, making the most of every available metre while respecting setback requirements and heritage controls. The key is smart design that maximises light, uses the rear yard well and creates functional spaces even on constrained sites. Many terraces here have more potential than owners realise.
