Our panelised prefabricated system is the best way to build a high performance, highly energy efficient and healthy home in Sydney and NSW.

Our panelised Passive House prefabricated system builds houses that are ultra energy efficient, comfortable and healthy for you and your family to live in.

Whether you are building a new home or renovating an existing home. Our Prefabricated building system is designed for the Australian environment to build new houses and renovations .

Our Passive House prefabricated building system will build for you the healthiest, most comfortable and most energy efficient home available.



Our prefabricted Passive House system creates the healthiest, most comfortable and high-performance building that you can live in.

Our Passive Houses are designed to optimise natural light and warmth, whilst minimising unwanted drafts and airflow. This creates a truly comfortable, highly energy efficient home that’s warm in winter, cool in summer, free from uncomfortable draughts and unhealthy dust and mould.

Our Passive Houses you will typically reduce your energy bills by 80-90% for heating and cooling, compared to a traditionally built home. So your house can easily be net zero for energy use.

The Passive Houses and renovations built with our building system meet the most rigorous building performance standards, delivering what’s important today and into the future: health, comfort and highest-level energy efficiency.

Every one of our Passive House and energy efficient homes and renovations has:

  • Double and triple glazed windows and doors to eliminate condensation and hot and cold transfer
  • Super insulation to floor, walls and roof to eliminate any cold and hot spots in the house and to prevent the build up of any mould
  • Airsealed construction to eliminate unwanted airflow in your house through the windows, walls and floors
  • No thermal bridges to eliminate hot and cold spots that can develop in floors, walls and roof structure
  • Optimal orientation to maximise natural light and warmth and cool
  • Mechanical ventilation to provide fresh filtered air inside whilst preventing warm or cool air from escaping

Airsealed Construction

A standard house has significant air leakage from the inside to the outside, and from the outside to the inside. This causes uncomfortable drafts in the house, hot or cold spots and potential condensation and mould build up.

Air leakage from a house also causes the heating and cooling system to be heating or cooling the new external air that continually enters your house.

Air leakage in a standard house is very common through and around windows, through and around external doors and through flooring and roof framing.


The key to delivering all the comfort and health benefits possible in our Passive Houses is ensuring the home is airsealed and that it has none of this air leakage.

Our prefabricated, panelised building system is specifically designed to eliminate any air leakage in the building, so you’ll always feel comfortable – and you will have the healthiest indoor environment possible.




Our prefabricated systems allows freedom of design, while providing speed in construction and GUARANTEED quality

When we prefabricate the building envelope (floor, walls and roof panels) of your home or renovation in our factory-controlled conditions, we can ensure precision manufacturing, predictable delivery time frames and quality control that is guaranteed to meet Passive House performance standards.

Our prefabricated building system is what is called closed panel. This means that the floor, wall and roof panels are fully insulated, membrane covered, airtight and watertight straight out of the factory.

For OWNER BUILDERS our prefabricated design and build system is the perfect way to have the structure of your house built to an ultra efficient or Passive House standard by us, leaving you to complete the rest of the build.

The on-site construction time is reduced to a fraction of traditional site builds, which reduces the cost of building and it eliminates any exposure to unpredictable weather. Our prefabricated envelope is typically installed on site in 1 – 2 weeks and the house is watertight and can be locked up straight away.

Design freedom with prefabrication




Prefabrication doesn’t usually bring to mind design freedom, but at eclipse, our prefabricated, panelised building system allows enormous design flexibility.

Are you an owner builder?

Then our prefabricated design and build system is the perfect way to have the envelope of your house built to an ultra efficient or Passive House standard by us, leaving you to complete the rest of the build. This means we guarantee the quality and performance of the most complicated part of the build for you.

Our design and build system is highly customisable to allow you to create the home you want, on the site you have. We can prefabricate, deliver to site and install your house it in a fraction of the time it would take with traditional site-built construction. Because your house is prefabricated, then compared to traditional site built construction it will be built to a far superior quality and will have guaranteed airtightness.
