Home Extensions Warrawee
Built For The Way You Live
Warrawee homes are predominantly single storey brick and weatherboard residences built between the 1960s and 1980s, sitting on generous blocks that often exceed 800 square metres. Many original floor plans feature smaller living areas and dated layouts that don’t match how families live today. The established blocks and solid foundations make these homes ideal candidates for well planned extensions rather than buying elsewhere.
We’ve completed numerous extensions throughout Warrawee and surrounding suburbs like Turramurra and Wahroonga, working with the local character and council guidelines. Our projects range from rear ground floor extensions that open to north facing gardens through to full second storey additions that take advantage of views towards the Lane Cove valley. Every extension is designed to complement the existing home while delivering the modern space families need.
Warrawee offers excellent schools, mature gardens and a genuine community feel that makes homeowners want to stay put rather than upsize elsewhere. With median house prices well above Sydney averages, a thoughtfully designed extension delivers far better value than selling and buying bigger in the same area. The right extension can add $300,000 to $500,000 in property value while giving you exactly the home layout your family 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."

Second storey additions generally begin around $250,000 for a complete upper level.

A single level rear extension might take three to four months, while a full second storey addition typically requires five to six months. We provide a clear timeline during quoting so you know exactly what to expect.
Do I need council approval for a home extension in Warrawee?
Most extensions in Warrawee require either Development Application or Complying Development Certificate approval through Ku-ring-gai Council. Some minor additions may qualify for exempt development but this depends on size, setbacks and other planning controls. Our team manages the full approval process including plans, submissions and any variations needed to get your extension approved.
Can I add a second storey to my single storey Warrawee home?
Yes, most single storey homes in Warrawee are structurally suitable for a second storey addition, though this depends on existing foundations and the age of your home. We arrange structural assessments as part of the design process to confirm what’s possible. Second storey extensions are popular in Warrawee because they maximise living space while keeping your established garden intact.
