A tiny house on wheels is classed as a caravan/RV, which avoids some building approvals but limits where you can legally live in it long-term. Check your council's rules before committing.
Tiny houses span a wide range, a basic kit versus a high-end house on wheels differ by three times. The big questions are on-wheels versus fixed (which affects approvals and where you can live) and how much you fit out.
Ways to save
- A flat-pack kit you finish yourself is the cheapest path if you have the skills and time.
- Off-grid systems add cost but open up land without services, weigh that against a connected site.
- Check council rules on where you can legally live in a tiny house before building, it affects the whole decision.

What a tiny house costs in Sydney
A tiny house in Sydney is costed first by whether it is built on a trailer as a movable dwelling or set on a fixed foundation as a permanent one, because that single decision governs the approval it needs, how it connects to services, and much of the price. A tiny house on wheels is generally treated like a registered caravan or movable dwelling and can often avoid full building approval, while a fixed tiny house on footings is a dwelling that must meet the building code and gain approval, so the trailer-or-footings choice leads the figure as much as the fit-out and the size.
In Sydney, where land and housing are the most expensive in the country, a tiny house is popular as a backyard secondary dwelling or a cheaper path to a home, but a fixed secondary dwelling on an eastern-suburbs block must satisfy council planning and the building code, which can be the harder hurdle than the build itself. A movable unit still needs power, water and waste handled, by connection or off-grid tanks and solar, and the compact, high-quality fit-out of a small space is dear per square metre. The city's highest trade rates lift the build, and a strata property generally cannot host one without owners corporation consent.
A fixed tiny house is a dwelling that needs a licensed builder, with building and planning approval, and licensed plumbers and electricians for its services, in New South Wales under NSW Fair Trading, while a trailer unit's gas and wiring still need licensed trades. For a Sydney tiny house, the clearest way to price it is by whether it is a movable unit or a fixed dwelling, then the size, the fit-out and the services.
