Tiny Home Design Brief Generator (Australia)
Turn early project requirements into one brief you can send to several builders. It covers intended use, build format, layout, access, services, site constraints, budget and the documents to ask for.

Your output
A consistent brief for builder quotes
The tool does not send or store your answers. Generate the brief, check it, then copy or print it for each builder.
How to use the brief
- Complete it before asking for detailed prices. Use the same brief for each shortlisted builder.
- Mark unknowns honestly. A clear “not checked” is more useful than an assumption about the site or approval pathway.
- Ask each builder to identify exclusions and the information needed before an estimate becomes a reliable quote.
- Compare the written responses with the builder comparison worksheet.
Why use and build format come first
A tiny house on a trailer, a fixed Class 1a dwelling, a modular cabin and a non-habitable studio can look similar online while requiring different documents, consultants and site work. The design should not get ahead of that distinction.
If you have not chosen a site, treat every layout as provisional. Orientation, delivery access, slope, soil, bushfire, flood, wastewater and local planning controls can all change a workable brief.
Layout questions buyers often miss
Daily movement
Check door swings, bed access, head height, stair or ladder use, bathroom circulation and where wet shoes enter.
Storage and work
List full-height items, pantry needs, laundry, linen, outdoor equipment, work-from-home gear and anything that needs ventilation.
Privacy and noise
Explain whether two people need separate work or sleep zones, and whether the project will host paying guests.
Long-term access
Raise step-free entry, a ground-floor bed, shower access, door width and future support needs before the plan is fixed.
Climate response
Ask how windows, shading, insulation, ventilation and materials respond to the actual climate and orientation.
Services
Size off-grid equipment from a real appliance and occupancy list, not a generic promise that a cabin is “off-grid ready”.
Worked example
A couple planning a fixed secondary dwelling in regional NSW might nominate a ground-floor bed, step-free entry, separate laundry, mains power, rainwater storage and a constrained driveway. The generated brief then prompts each builder to separate the factory build from foundations, approvals, services, delivery and site installation.
That does not prove the project is allowed or set a price. It makes the missing checks visible before several quotes are compared.

Method and source notes
The prompts reflect the Australian Government's advice to resolve site, orientation, climate, household needs and budget during design, and the ABCB's guidance that prefabricated and modular projects still need suitable compliance evidence and a clear chain of responsibility.

- Australian Government Your Home: orientation
