When we think of Tiny Homes, we often picture the Instagram-worthy Tiny Houses on Wheels we see online.
But Tiny Houses on Wheels aren’t for everyone.
They were largely developed as a way to avoid building and planning approvals.
But if you already own your own property, that doesn’t always make sense.
If your property allows for a fixed dwelling or secondary dwelling, a Tiny Home on foundations could be a much better long-term option.
So, what are the benefits?
🏡 Permanency and certainty
A fixed Tiny Home is designed and approved as a permanent dwelling and is subject to the normal planning and building requirements that apply in your area.
That means you aren’t relying on uncertain rules around whether a dwelling on wheels is permitted on your particular property.
And importantly, legislation is changing across Australia. In places like Victoria, recent reforms have made it easier in many circumstances to add a secondary dwelling or granny flat to your property, often without the need for a planning permit, although a building permit may still be required.
✅ Built to the required standards
Choosing an accredited THIA member gives you access to experienced builders who understand the requirements for fixed Tiny Homes.
Our fixed Tiny Home builders also build in accordance with the National Construction Code, and most will assist you through the approvals process.
💰 More finance options
Finance for a THOW can be limited, with personal lending often being the primary option.
A fixed Tiny Home or granny flat, however, may open up different finance options, potentially including your existing mortgage by way of a refinance or redraw.
Important: This is not financial advice. Your available finance options will depend on your individual circumstances, lender requirements and the property itself.
For landowners, the combination of permanency, compliance and greater access to finance makes a Tiny Home on foundations an incredibly attractive option.
