How to read this prefab directory
Does the factory price include site works?
Usually not. Crane hire, piers, sewer, power metering and energy certificates sit outside the module invoice. Ask for a written split between factory and on-site costs before you compare two suppliers.
Do small granny flats skip NCC energy rules?
Ask the certifier which adopted NCC edition, state variations and energy compliance pathway apply to your project. The Australian Building Codes Board and NatHERS explain the relevant frameworks; a small footprint does not establish an exemption.
How should I shortlist from these cards?
Use city, tags and the supplier website, then call with your lot address and overlay. The Granny Flat Guide Team does not build or sell these homes; we list public supplier details so you can compare factory vs site-built options.

A factory-built home still needs a prepared site. Ask each supplier to separate the module price from foundations, transport, crane hire and connections so you can compare the same finished result.
Modular vs Kit vs Prefab
“Prefab” is an umbrella term. The build method changes your delivery, site works and resale options.
Volumetric Modular
Built as three-dimensional modules in a factory, then transported to site. The completion stage, lifting method and foundation design depend on the project.
Panelised Prefab
Walls and roof are built as flat panels (SIPs or timber frames), trucked to site and assembled like a jigsaw.
Relocatable
Designed for transport, often on a chassis. Ask whether the home can be moved again and what engineering, approvals and transport costs that would involve.
What to Ask Before Choosing a Prefab Provider
Three questions that separate a clean delivery from a budget surprise.
What does “turnkey” really mean?
Ask whether delivery, crane hire and site access work are included. Powerlines, trees and narrow driveways can affect installation. Get a site-specific access quote before signing.
Visit the factory or display home
Never buy off a floor plan alone. Inspect the frame quality and how modules are stored before delivery.
Chassis engineering and resale value
For relocatable homes, ask whether the chassis is rated for a single lift or multiple lifts. It affects future resale.
Don’t Start Building Without a Budget
