Duplex design and lifestyle benefits

Australia is experiencing a cost of living crisis on one hand and a desire to strengthen community bonds on another. This type of living provides a solution to both whilst still maintaining independence and privacy.

  • Solid investment opportunities 

This is an excellent option for those who want to live in one unit and generate a rental income in the other whilst keeping a close eye on things. It can also reduce shared expenses across common utilities such as water.

  • Independent living for extended family or guests 

Like dual-living home designs, families can be together without feeling like they’re living on top of one another. This solution allows a more fluid way for families to mix, seeking out connection when they want it and maintaining their own quiet time when it suits them.

  • Flexible lifestyle solutions 

Don’t limit your imagination! This kind of dwelling can be a terrific option for a work-from-home office.

Knockdown Rebuild

My husband and I started to plan our knockdown rebuild back around April 2021. During this time we visited many display homes and builders and we ended up choosing to build with Kurmond Homes.
Christine was great, she was always contactable and accommodating to all our needs she also helped and guided us with modifying the Affinity 40.
The colours team at Kurmond Homes Kristen and Morgan helped every step of the way providing great advise and ideas that simplified the selection process for us.
Like everyone else looking to build around this time we had some challenges with COVID it has taken some time to get to the construction stage and we couldn’t be more pleased with our site supervisor Steve.
Steve has so far been exceptional at keeping us in the loop and explaining things for us to better understand the construction process. We could not be happier with our experience so far and look forward to continuing our building journey with Kurmond Homes.
Ray and I are so excited and can’t wait to see our finished home.

Our experience from start to end with our Sales Consultant Mike has been exceptional. He is professional, informative, goes out of his way to keep us up to date, communication excellent. Each step was processed unbelievably quick and he helped us every step of the way to find our dream home and tweak it to how we wanted. It has been an amazing journey so far with Kurmond, we are now in the Pre Construction phase and we are excited as we are now booked for our external colours.
Would definitely recommend Kurmond.

Custom build

My wife and I decided to build a secondary residence designed for our daughter and grandson. It had to complement the existing residence but was limited in size by council regulations. Finding a builder prepared to build a design not their own and on the smaller size was not easy until we met Mike for Kurmond. Not only were Kurmond prepared to take on the task but they were enthusiastic. Their systems were more than capable and flexible enough to quickly quote an assist with the DA processes.
Their costings were a pleasant surprise, custom builders usually don’t have the volume to get buying power. All of the selections were very efficient and straight forward. So far it’s been a great experience. Thanks Kurmond.

It was a great experience working with Kurmond Homes as they provided everything we wanted/needed in our new home and more. The staff and team at Kurmond Homes were very helpful and had great communication with us, they helped every step of the way, simplified what we needed to do on our end so they could do their part and answered all our questions if we had any so that we weren’t left in the dark. In the Pre construction phase the Kurmond team provided us with excellent knowledge and great inputs in order to narrow down our choices in what features we wanted. In the construction phase our site supervisor Dhaval Patel did a tremendous job on keeping us in the loop, helped us with other aspects of the build of what had to be done and explain things for us to better understand. Overall our experience with Kurmond Homes was amazing together with their quality workmanship and pricing, would recommend them to anyone looking to build a home.
