What we do
At Co.Coon, we believe every project - big or small - deserves care, craftsmanship, and heart. Whether it’s a simple ramp to help someone stay independent, a deck for long summer conversations, or a full-scale home extension, we find deep satisfaction in creating spaces that improve lives.
With over 20 years of building experience across Norway and Australia, we bring a unique blend of Scandinavian precision and Aussie practicality to every job. We listen, we deliver, and we build spaces that feel like home - warm, functional, and built to last.

Residential renovations & small-to-medium building projects
We believe a home should be a cocoon – a safe, warm, and healthy space. That’s why we build with care, integrity, and a commitment to excellence.
Interior renovations
We help you get more from the home you own. From new flooring, kitchen, bathroom, and laundry renovations to full rebuilds, we create homes that feel better, flow better, and work better for your life. With every project, we bring thoughtful design, quality finishes, and a commitment to get it right.
Exterior upgrades
We give homes a fresh face and stronger bones. From recladding and insulation to new windows, doors, decks and terraces, we improve your home’s performance and street appeal. These upgrades do not only look great but make your home more comfortable, efficient, and enjoyable to live in.
Extensions and additions
Need more room to grow? We build seamless extensions, garage conversions, and additional living spaces that feel like they’ve always belonged. Where practical, we incorporate Passive House principles to ensure your home is future-ready — comfortable, efficient, and built to last.
Smart, sustainable homes
We apply Passive House techniques to create homes that are healthier, quieter, and more energy-efficient. With airtight construction, superior insulation, and heat recovery ventilation, these builds offer year-round comfort with minimal heating and cooling. It’s a smarter way to build - and a better way to live.


Building for the Future - Passive House
Our mission is simple: to build better. We create homes that are comfortable, beautiful, and joyful to live in. Too many Australian homes -new and old- are freezing in winter and sweltering in summer, relying heavily on expensive heating and cooling.We believe there’s a better way. Drawing on our experience in Norwegian cold-climate construction, we adapt proven techniques to suit the Australian environment. The result? Homes that feel good to be in - whether it’s January or July.
Where possible, we apply Passive Housing techniques – a premium standard for energy-efficient, comfortable homes. These principles include:
-
Airtight construction
-
No thermal bridging
-
Superior insulation
-
Mechanical ventilation with heat recovery
-
Double-glazed windows and high-quality external doors
This approach ensures your home stays comfortable year-round, with minimal energy use.
We’re proud to be a Certified Passive House Tradesperson through the Passive House Institute (PHI), and an active member of both the Australian Passivhaus Association and the Housing Industry Association (HIA). These affiliations reflect our commitment to best practice, ongoing learning, and raising the standard of Australian building.
