Tiny houses have become increasingly popular in Australia, and it’s easy to see why. A tiny house from Tiny Home QLD offers a cozy, practical living space that can be positioned wherever you desire, far removed from the hustle and bustle of urban life. The mobility of these homes on wheels provides unmatched flexibility, allowing you to adapt your living situation as needed.
However, living off-grid is not for the faint-hearted. It requires a degree of resilience and self-sufficiency. This guide will walk you through the essential steps and costs involved in setting up your off-grid tiny house, covering the six key areas you need to consider.
1. Site Access: Getting Your Tiny House in Place
The first step in setting up your tiny house is figuring out how to transport it from the main road to your chosen site. Whether your location is easily accessible or tucked away in a secluded spot, ensuring the delivery truck can maneuver the house into position is crucial. This might mean trimming back branches, filling in potholes, and preparing any difficult terrain ahead of time. Additionally, if your tiny house will be situated in a rural paddock, consider how you’ll access it regularly—you don’t want to get stuck in the mud.
2. Preparing the Site: Establishing a Solid Foundation
Once you’ve picked the perfect location, you’ll need to prepare the ground. Start by clearing and leveling an area roughly the size of your tiny house—about 2.5 meters wide by up to 9 meters long. You have several options for the foundation: a 100mm thick concrete pad, concrete footings under the house’s adjustable legs, or a 100mm thick layer of compacted gravel or road base. Ensuring your tiny house has a stable, level foundation is key to avoiding future issues with subsidence.
3. Powering Your Off-Grid Tiny House: Utilising Renewable Energy
To live off-grid, you’ll need a reliable source of power. Tiny houses are designed with energy efficiency in mind, meaning they require significantly less power than traditional homes. Solar panels are an excellent choice, being both eco-friendly and cost-effective. A local solar installer can help you determine the right system size based on your energy needs, typically including at least 6 solar panels, a 4-8 kWh battery, a 5,000W inverter, and an autostart backup generator. This setup ensures you’ll have enough electricity to cover your daily needs, with a reserve for cloudy days or nighttime use.
Estimated Cost: $8,000 – $20,000
4. Water Management: Ensuring a Steady Supply
Effective water management is essential for off-grid living. Install guttering and downpipes to capture rainwater, directing it into a water tank with a capacity of at least 5,000 liters—sufficient for a couple or small family. To keep the water clean for drinking, cooking, and washing, consider adding a filtration system. You’ll also need a water pump to move the water from the tank into your tiny house.
Estimated Cost: $1,000 – $3,000 for the water tank; $2,000 for the filtration system
5. Waste Management: Handling Your Off-Grid Needs
Dealing with waste is another crucial aspect of off-grid living. Options include traditional flush toilets connected to a septic tank, composting toilets, or gas/electric incinerator toilets. Composting toilets are particularly popular for their low maintenance and eco-friendliness, turning waste into nutrient-rich compost. If your tiny house is near a body of water, an incinerator toilet might be the required solution due to environmental regulations.
Estimated Cost: $1,500+ for a composting toilet
For greywater—wastewater from sinks, showers, and appliances—you’ll need a system to filter and safely dispose of it, typically involving a slotted pipe, grease trap, and gravel trench.
Estimated Cost: $500 – $1,000
6. Rubbish Management: Keeping Your Space Clean
Managing household rubbish in an off-grid setup requires some planning. Depending on your location, you may have access to council or private waste collection services. If not, you’ll need to sort and dispose of your rubbish at a local depot. Recycling as much as possible will help reduce waste and its impact on the environment.
Additional Considerations: Heating and Cooking
- Gas Bottles: Using gas for cooking and hot water reduces the load on your solar power system, making it a practical choice for off-grid living. Estimated Cost: $500 per year
- Wood Fire Heater: For those living in colder climates, a wood fire heater adds warmth and ambiance, and can even be used for cooking. Estimated Cost: $4,500+
Total Cost Breakdown
Setting up an off-grid tiny house requires a significant investment. The total cost for a fully self-sufficient setup typically ranges between $20,000 and $30,000, with solar power being the most significant expense. This includes everything you need—from solar panels to waste management systems—to live independently and sustainably in your tiny house.
Embracing off-grid living in a tiny house offers a unique blend of freedom and sustainability. With careful planning and the right setup, you can enjoy the benefits of a simple, self-sufficient lifestyle, knowing that your home is as adaptable and resilient as you are.
