What Exactly Is a Tiny Home?
A tiny home in Australia typically:

Sits on a trailer (THOW, Tiny House on Wheels) or on foundations as a cabin/studio
• Focuses on minimalist design and multi-functional spaces
• Utilises sustainable materials and off-grid technologies

| Fixed Tiny Home | Built on a slab or stumps | Larger footprint possible, higher ceilings | Requires DA, building code compliance |
| Container Conversion | Repurposed shipping container | Strong, secure, quick build | Thermal regulation, insulation challenges |
| Modular Panels | Flat-pack or SIP panels assembled on-site | Rapid installation, excellent insulation | Transport costs for rural areas |
