Home Extensions Crows Nest
Built For The Way You Live
Crows Nest has a mix of federation homes, 1920s bungalows and 1960s brick homes, most sitting on compact blocks between 300 and 500 square metres. Many original homes were built with just two or three bedrooms and a single bathroom, which doesn’t suit how families live today. An extension lets you add the space you need without leaving a well located suburb with excellent schools and transport.
We’ve completed dozens of extensions throughout Crows Nest and nearby suburbs like Neutral Bay and Waverton, working with the tight site constraints common in the area. Our team knows how to maximise usable space on smaller blocks while meeting North Sydney Council requirements. Whether you’re adding a second storey, extending out the back or creating an open plan kitchen and living area, we’ll design a solution that works for your home and your budget.
Crows Nest properties hold their value well due to the location and lifestyle on offer, with cafes, shops and the train station all within walking distance. Adding a well designed extension can increase your property value by $200,000 or more while giving you the extra bedrooms, bathrooms or living space your family needs. It’s often more practical and more affordable than moving, especially when renovation costs are weighed against stamp duty and agent fees.

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?

We provide a free quote after assessing your property and understanding what you want to achieve. Every project is different, so we price based on your specific home and requirements.
How long does a home extension take in Crows Nest?
Most home extensions take between three and six months from council approval through to final handover, depending on the size and complexity of the build. We’ll give you a detailed timeline during the quoting process. Weather, material supply and any unexpected site conditions can affect timing, but we keep you informed every step of the way.
Do I need council approval for a home extension in Crows Nest?
Most extensions require either Development Approval or a Complying Development Certificate from North Sydney Council. Some minor alterations can be done as exempt development, but this is rare for anything that adds significant floor area. We manage the full approval process including plans, documentation and council submissions so you don’t have to.
Can you extend a small block in Crows Nest?
Yes, we regularly work on compact blocks throughout Crows Nest where site access and setback requirements need careful planning. Going up with a second storey is often the best solution when ground level space is limited. We’ll assess your block and design an extension that maximises space while meeting all council regulations.
