Family-owned property developers in Sydney
Looking to build, extend or renovate your home? We’ll care for you like family — because we’re a family ourselves. Orth Property Group is owned and run by four siblings: Larissa, Phillip, Robert and Peter. With a combined 100+ years of property development experience, we can make your dream home a reality.
Building practical yet elegant spaces where your family can create lasting memories
For us, building homes is about much more than just construction — it's about creating sanctuaries. We believe your home should be a retreat from the outside world, a place that nurtures your soul and feels great to live in.
Whether redesigning a kitchen, building a custom home or tackling a major renovation, we don't just react to the present. We envision your future needs and space, map out the steps to get there, and execute with precision to deliver practical, timeless and awe-inspiring results.
Our building philosophy: do it once and do it right
When you partner with us for your home construction or renovation project, you're not just getting highly skilled tradespeople — you're collaborating with a group of passionate individuals who truly love what they do.
This is crucial because renovating or building your new home is often one of life’s biggest investments. Allow us to take the stress out of building by managing the entire process for you. As experienced property developers in Sydney, we’ll meticulously watch over every detail of your project and creatively solve any problems within budget, ensuring the highest quality of work and true value for money.

Meet our Founders
We’ve always been a close family. The four of us grew up together on the South Coast and in Sydney, inspired by the strong work ethic of our parents and their keen interest in residential property development.
That sparked distinguished property developer careers in Sydney:
Robert studied engineering and founded CD Construction Group in the early 2000s, building it up to a $50 million business.
Larissa went into retail and franchising property development, overseeing hundreds of large building projects for a multinational food brand.
Phillip studied carpentry and building, and tackled almost every project imaginable during three decades within the business he launched at age 22.
Peter built a 25-year construction career with roles at Scentre Group (Westfield) and Probuild, working across residential, commercial, heritage and health projects.
In 2022, we decided to combine this extraordinary depth of experience across every facet of property development — and launched Orth Property Group.
Our History

Our Values
Philosophy
Design
-
Australian-Inspired
The Australian way of life inspires all our designs. Picture long summer evenings, laughter, family gatherings and children splashing in the pool — this seamless indoor-outdoor living is an essential part of our cultural DNA and central to every home we create.
-
History and Character
We believe in the value of existing structures. Where others see old homes to demolish, we see history worth preserving and the potential for something special. By reimagining and repurposing these spaces, incorporating recycled materials and preserving original features, we create homes with authentic character.
-
Energy Efficient
We design homes that work with Australia's challenging climate, rather than against it. We prioritise energy efficiency and smart design principles that help manage our harsh summers and cool winters, to create comfortable living spaces year-round, while minimising environmental impact.
