modular homes


Modular homes are sectional prefabricated buildings that consist of modules. These modules are 6 sided boxes, fabricated in a remote facility, then delivered to site and craned into position.


  • Speed of construction-work within factory and on site can be done simultaneously.
  • Indoor construction eliminates the effects of weather.
  • Ability to service remote locations.
  • Reduced waste.
  • Sustainability-the building could be disassembled and reused, reducing the amount of embodied energy by up to 97%.


  • Volumetric-transportation takes up a lot of space.
  • Flexibility-transport and manufacturing restrictions could limit module size.


Architect Nonda Katsalidisand Hickory Group developed Unitised Building Systems. This system has been engineered for multi unit developments, up to 70 storeys.

They are able to engineer and prototype their modules to suit your requirements.

Like other modular systems, you have less material and energy waste, and significant time savings.


  • Timber frames for houses can also be factory built. Whilst preparing the site; floor, wall and roof trusses can be assembled in the factory, brought to site and erected.
  • SIPS (Structurally Insulated Panels) is another product fabricated in the factory. This system also includes floors, walls and roofs.
  • These systems do lend themselves to ‘one off’ designs, but there is nothing stopping you from using a mix of modular units and other systems.

In summary,

Modular and factory built systems are ‘innovative’, however, less that 1% of new homes built in Western Australian use these systems; even though they produce less waste, use less energy and save time.
