Panelised Prefabrication	Floor Cassettes	Pre-framed floor panels with services, fire rating, and insulation.	Low – Gaining traction for fast-track residential builds.	Increasing interest in multi-res and modular integration.	Requires engineering certification; emerging NCC guidance on acoustic/fire compliance.
Volumetric Modular Construction	Modular Homes and Apartments	3D units fully constructed off-site and assembled into buildings.	Low – 3–5% of national builds; forecast to grow to 10–15% by 2030.	Expected to double in share due to housing demand and policy shifts.	Subject to NCC and local planning approvals; performance-based pathways used.
Volumetric Modular Construction	Workforce/Mining Dongas	Temporary or semi-permanent site accommodation units.	Very High – Over 30,000 units across mining/resource projects.	Sustained in mining/resources; potential smart upgrades.	Classed under temporary structures; compliance with energy and cyclone requirements.
Volumetric Modular Construction	Modular Classrooms, Healthcare	3D units for education and medical use, built off-site.	High – State governments regularly procure modular school rooms.	Government procurement driving growth.	Must meet education and healthcare building regulations; prefabrication certified per state.
Hybrid Prefabrication	Bathroom/Kitchen Pods	Fully finished wet area modules installed into conventional buildings.	Moderate – Common in healthcare/hospitality; standard for bathrooms.	Standard in hotels/hospitals, expanding into residential.	Pods require certification under NCC for waterproofing and fire; typically third-party inspected.
Hybrid Prefabrication	MEP Riser Modules	Pre-integrated service shafts and risers craned into place.	Moderate – Used in vertical MEP integration in towers and hospitals.	Growth with BIM integration and smart systems.	Must meet plumbing/fire code; risers often certified off-site and documented via BIM.
Hybrid Prefabrication	Facade Systems	Pre-glazed or insulated cladding units.	Moderate – Adopted in high-rise for speed and thermal performance.	Increased use in mid/high-rise, fire-tested assemblies trending.	AS 4284 for facade testing; fire rating and water penetration test required under NCC.
Complete Building Units	Transportable Homes, Granny Flats	Self-contained units trucked to site, installed on foundations.	Moderate – 10–15% of regional housing approvals involve relocatables.	Rising in affordability-driven markets and regional areas.	Classed as relocatable buildings; NCC compliance varies with intended permanence.
Complete Building Units	Tiny Houses on Wheels	Factory-built micro homes registered as trailers.	Niche – Popular in alternative housing, still <1% market share.	Popularity rising in alternative housing markets.	Often exempt from NCC if road-registered; otherwise treated as small dwellings.
