With the rising demand for affordable, flexible, and sustainable housing, more buyers are considering alternative home options like Tiny Houses on Wheels (THOW), Certifiable Tiny Houses, Modular Homes, Granny Flats, and Prefab or Kit Homes. Each of these options comes with its own unique features, costs, and benefits, but for those prioritising affordability, mobility, and a minimalist lifestyle, one stands out as the most versatile solution.
What is a Tiny House on Wheels (THOW)?
A Tiny House on Wheels is a fully functional home built on a trailer chassis, making it mobile and legally classified as a caravan in Australia. THOWs typically range from 10m² to 30m² and are designed for efficient, sustainable living. They often include clever space-saving solutions such as loft bedrooms, foldable furniture, and off-grid capabilities like solar power and composting toilets.
Why buyers love THOWs:
- Mobility & Flexibility: Move anywhere without committing to a permanent foundation.
- Lower Costs: No land purchase required if parked on leased or shared land.
- Minimalist Living: Encourages a clutter-free, low-maintenance lifestyle.
- Eco-Friendly: Smaller footprint, energy-efficient, and sustainable building materials.

What is a Certifiable Tiny House?
A Certifiable Tiny House is a permanent or semi-permanent home that meets Class 1a building codes, making it a legally recognised dwelling and an ideal option for downsizing. Unlike a THOW, it may or may not be on wheels but is built to the Australian Building Code, making it easier to insure and finance.
Why Consider a Certifiable Tiny House?
- Council-Approved: Recognised as a legal dwelling (Class 1a).
- Better Financing Options: Can qualify for home loans and First Homeowner Grants.
- Increased Resale Value: Holds value better than a traditional THOW.
- Still Offers Small-Scale Living: Designed for minimalism but with enhanced durability.

What is a Modular Home?
A Modular Home is a prefabricated structure that is built in sections (modules) at a factory and then transported to the site for final assembly. Unlike THOWs, modular homes are designed to be permanent dwellings that sit on a foundation, making them like traditional houses in terms of structure and compliance.
Key Considerations:
- Higher Cost: While cheaper than a traditional home, it still requires land and installation expenses.
- Limited Mobility: Once installed, it cannot be moved.
- Council Approvals Required: Subject to zoning regulations and building codes.
- Resale Value: Holds value like a conventional house.
What is a Granny Flat?
A Granny Flat is a self-contained secondary dwelling built on the same property as a main house. It’s often used for aging parents, rental income, or guest accommodation. Unlike THOWs, Granny Flats are fixed structures and are subject to local zoning laws and property setbacks.
Things to consider:
- Adds Property Value: Can increase home resale value and rental potential.
- Fixed Location: Cannot be relocated like a THOW.
- Requires Council Approval: Must comply with local regulations and space restrictions.
- Utility Costs: Shares services with the main house but still incurs expenses.
What is a Prefab or Kit Home?
A Prefab or Kit Home consists of pre-manufactured parts that are transported and assembled on-site. While like modular homes, kit homes require more onsite construction, making them more customisable but also more labour-intensive.
Pros & Cons:
- More Affordable than Modular Homes: Buyers can choose DIY assembly to reduce costs.
- Requires Foundation & Land: Unlike THOWs, it’s a permanent structure.
- Longer Build Time: Unlike THOWs or modular homes, more time is needed for assembly.
- Council Approval & Compliance: Subject to building regulations like a standard home.
Why Many Buyers Choose a THOW as the Best Choice
While all tiny house options have their place, a Tiny House on Wheels offers unique benefits that make it the most flexible and cost-effective solution for many people and here’s why:
THOWs are the Most Affordable

- No lengthy construction periods—most THOWs are built in 4 to 6 months.

- Ready to live in as soon as it’s parked.
Sustainable & Off-Grid Capabilities
- Solar panels, rainwater tanks, and composting toilets allow self-sufficient living.
- Lower carbon footprint compared to larger homes.

Ideal for First-Time Homebuyers & Downsizers

Key Considerations Before Choosing a THOW
If you’re leaning toward a Tiny House on Wheels, here are a few things to consider:
- Parking: Find land or caravan-friendly zones for legal placement.
- Towing Regulations: Ensure your vehicle can tow the THOW legally. To make Tiny House on Wheels (THOW) towing legal, the THOW must be properly registered, meet weight and safety standards, and the towing vehicle must have sufficient towing capacity. It must also adhere to local size and safety regulations, including brake systems, safety chains, and lights, and comply with zoning laws for parking or living.
- Insurance: Some providers offer THOW-specific policies.
- Lifestyle Adjustments: Downsizing requires smart storage solutions and adaptability.
Each housing option—THOW, Modular Home, Granny Flat, and Prefab or Kit Home—offers unique benefits, but for those seeking an affordable, flexible, and eco-friendly lifestyle, a Tiny House on Wheels is hard to beat. Whether you want to live off-grid, travel, or simply avoid the financial burden of traditional homeownership, a THOW offers the freedom to design a lifestyle that works for you.
