How Much Does a Granny Flat Cost?

Thinking about installing a granny flat in your backyard? Whether you’re looking to accommodate elderly family members or earn rental income, a granny flat can be a good solution. 

Granny flats provide affordable housing, without the hassles and expense of permanent dwellings. They can be easily relocated as your family’s needs change, giving you flexibility. 

Now you’ve considered the benefits of installing a granny flat, you’re probably wondering how much it’s going to cost. In this article, we’re sharing our insights into granny flat prices, additional expenses, and ways to reduce costs. 

How Much Does a Granny Flat Cost? 

There are many factors that can influence the price of a granny flat, including its size, the amenities included, and the types of materials and finishes used. For example, a larger granny flat with multiple bedrooms, bathrooms and luxury details will be more expensive to install. Let’s take a look at the typical prices for common granny flat sizes. 

One-bedroom granny flats are an affordable and compact option for accommodating extended family members. They can be useful if you don’t have much space in your yard. Ranging from 35m2 to 45m2, up to 60m2, these flats typically cost $90,000 to $120,000

At 60m2, two-bedroom granny flats are a more spacious option for accommodating family members or rental tenants. These flats are self-contained, giving elderly or disabled relatives the independence, privacy and comfort they desire, whilst still being close to home. Although prices vary, they typically range from $130,000 to $150,000

Three-bedroom granny flats offer the comforts of a typical house for a fraction of the cost. They are a popular choice for rental properties, especially if you have lots of backyard space or are located close to universities or tourist attractions. Although the size is restricted to 60m2 as a secondary dwelling, there’s still ample space for three bedrooms, kitchen and living space if designed properly. Prices range from $140,000 to $180,000

Additional Costs 

When it comes to the costs of installing a tiny home, there are additional expenses you also need to consider. These can include:

  • Preparing your yard 
  • Laying a slab or foundation
  • Getting council approvals
  • Planning and design costs 
  • Building and material costs 
  • Connecting to plumbing and electricity 
  • Fixtures and finishes 

How to Reduce Granny Flat Costs 

If you’re feeling overwhelmed about granny flat costs, don’t stress. There are some simple ways you can plan your project to reduce expenses. Let’s explore these below. 

1. Plan Your Design Wisely

A well-thought-out design can save you a lot of money. Choose a simple and efficient layout that maximises space usage. Avoid complex architectural features that can increase construction costs. Consider an open-plan design, which not only saves on building materials but also makes the flat feel more spacious.

2. Choose Cost-Effective Materials

Selecting the right materials can make a big difference in your budget. Look for durable yet affordable materials. For example, you can use vinyl or laminate flooring instead of hardwood. Consider prefabricated or modular construction options, which can be more cost-effective and faster to install than traditional building methods.

3. Choose a Prefabricated Granny Flat  

One way to save significantly on your granny flat cost is to choose a prefabricated option. This will be delivered to your site for you to install yourself, saving the expenses associated with hiring builders. Prefabricated granny flats are typically faster to assemble, allowing you to move in sooner and reducing the overall construction timeline. Just note it’s important to check with your local council for approval before purchasing your granny flat.    

Prefab granny flats offer numerous advantages to homeowners. These can include:

  • Cost effective 
  • Time efficient
  • Minimal disruption
  • Relocatable 
  • Financing options
  • Includes warranty and support 

At My Little House, we have a wide range of prefabricated granny flats available, from our compact 20ft Oasis to the luxurious 40ft Haven and more. Whether you want a cosy retreat for couples or a more spacious option for a family, we’ve got a tiny home to suit. 

4. DIY Where Possible

Taking on some of the work yourself can significantly reduce labour costs. Simple tasks like painting, landscaping, or even installing fixtures can be done on your own if you have the necessary skills and time. However, make sure to leave specialised tasks, such as electrical work and plumbing, to professionals to avoid costly mistakes.

5. Optimise Energy Efficiency

Investing in energy-efficient solutions can save you money in the long run. Install energy-efficient windows and insulation to reduce heating and cooling costs. Consider using solar panels to generate electricity, which can further reduce your utility bills over time.

7. Reuse and Recycle

Incorporate recycled or repurposed materials where possible. This not only reduces costs but also adds a unique character to your granny flat. Look for reclaimed wood, recycled bricks, or second-hand fixtures that are still in good condition.

8. Keep It Compact

Smaller granny flats naturally cost less to install and maintain. Focus on designing a compact, functional space that meets your needs. A smaller footprint reduces the amount of materials needed and can also lower ongoing costs such as heating, cooling, and maintenance.

9. Plan for Future Needs

Consider the future uses of your granny flat to avoid costly renovations later. Designing with flexibility in mind allows the space to be easily adapted for different purposes, such as a home office, guest suite, or rental property.

Summing Up 

Starting your granny flat journey can be an exciting venture, whether it’s to accommodate family members or earn rental income. If you’re ready to own your own granny flat, then you’re in the right place.
