Home Extensions Lavender Bay
Built For The Way You Live
Lavender Bay is home to a mix of Federation cottages, early century terraces and 1920s apartments built on some of the smallest blocks on the lower North Shore. With blocks often under 200 square metres and heritage overlays restricting external changes, many homes need better use of existing footprints. An extension becomes the only way to create the extra bedroom, modern living area or functional kitchen that families need without moving away from this waterside pocket.
We’ve completed extensions throughout Lavender Bay and neighbouring McMahons Point where sloping sites and tight access require careful planning and execution. Our team knows how to work within the constraints of these older homes, whether it’s adding a rear extension to a terrace or converting roof space into usable rooms. Every project is managed by our licensed builders who understand local council requirements and how to build on challenging North Shore sites.
Property values in Lavender Bay reflect the location and harbour proximity, with even modest homes commanding premium prices. Adding a well designed extension protects your investment by creating the space modern families expect while keeping you in one of Sydney’s most tightly held suburbs. With limited stock available and strong demand for family homes close to the city, an extension makes far more sense than selling and starting again elsewhere.

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 Lavender Bay?
A single room addition typically starts from $80,000, while a full ground floor extension begins around $150,000. Second storey additions start from $250,000 depending on design and site access. We provide a free detailed quote after assessing your property and discussing your requirements.
How long does a home extension take in Lavender Bay?
Most home extensions take between 3 to 6 months from council approval through to final handover. The timeline depends on the scope of work, weather conditions and any unforeseen structural issues common in older homes. We’ll provide a clear schedule before work begins and keep you updated throughout the build.
Do I need council approval for a home extension in Lavender Bay?
Most extensions in Lavender Bay require either a Development Application or Complying Development Certificate from North Sydney Council. Heritage considerations and site constraints mean many projects need a DA rather than the faster CDC pathway. Our team manages the full approval process including plans, submissions and any additional documentation required by council.
Can you extend on steep blocks in Lavender Bay?
Yes, we regularly work on sloping sites throughout Lavender Bay where many blocks fall towards the harbour. We handle the structural engineering and access challenges that come with steep blocks. Our builders are experienced with difficult sites and know how to deliver quality results where other builders won’t quote.
