Granny Flats vs. Tiny House: What’s Best For You?

Are you looking to make use of your extra backyard space? With Sydney’s growing demand for livable space, adding a tiny home or granny flat can unlock revenue and make your property more valuable. But which option is right for you? Actually, don’t answer that. We’ll answer it for you…

Are you tossing up between a tiny house or a granny flat?

Both structures are small and relatively affordable while expanding your living space. But there is a range of differences to take into account before choosing between these two abodes.

If you’re excited to downsize your life, create a secondary stream of rental income, or add value to your property, this article is for you. We’ll show you the major differences between Sydney granny flats and tiny homes, and help you decide which option is right for your space, budget, and lifestyle goals.

From price to council requirements and everything in between, read on to find out what sets these two independent living spaces apart.

What are the differences between a granny flat and a tiny house?

Similar in appearance, there are unique differences between granny flats and tiny houses. A granny flat is a self-contained house, typically built in the backyard of a family home. Coming in one, two, or three-bedroom floorplans, you’ve got flexibility over your size. This leads to a self-contained home connected to all necessary utilities.

A tiny house, in contrast, is a moveable dwelling with an average floor size of 39m2 and typically one bedroom. This makes it smaller than a granny flat. Tiny houses are typically no bigger than a caravan and don’t offer the same extended living space as a granny flat, but do present an affordable living option ideal for individuals looking to enjoy an off-grid lifestyle or avoid the permits and certifications needed for granny flat construction.

Both living spaces represent flexibility, but freedom comes in different forms. That freedom comes from the moveability of a tiny house. And it comes from a secondary living space in the form of granny flats.

Granny Flat: Pros and Cons

If you’re stuck between two options, a pros and cons list can help. When it comes to a granny flat, the major advantage comes from the high level of comfort. Modern granny flats are self-contained homes with all amenities from insulation, heating and cooling, WiFi, outdoor verandahs, and ample storage.

As a granny flat is a fixed asset, this makes it easier to get support from lenders who can finance your granny flat. Lenders have confidence in granny flats as they can add value to your property. With house prices in Sydney soaring, a granny flat creates a way to spread living costs and that’s attractive to potential buyers.

With the granny flat rental reaching up to $650 per week, one of the major advantages comes in the form of passive income.

As exciting as these benefits are, it’s important to recognise that granny flats aren’t as small an investment as a tiny home. Between council rules and the cost of construction, you’ll be investing time and money in a serious home improvement upgrade.

Tiny House: Pros and Cons

Don’t let the size of a tiny house fool you, there are plenty of advantages that come with this living space. For a start, a tiny home can be a flexible investment (if built with wheels) so you can move your tiny home anywhere you want.

A more affordable option than a granny flat, your own tiny house won’t require the financial obligation of granny flat design and construction. If you choose to downsize your life and move into your tiny house you can also save on bills with less cooling and heating required. Throw in the lack of paperwork required and a tiny house can be an appealing option.

However, a tiny house is just that - tiny. Not much bigger than a caravan, a tiny home isn’t the type of space to host friends or family. It’s also not ideal for more than one person or a couple. This means you won’t be able to generate close to the same rental income as a granny flat as there is less space (which means less storage, fewer amenities, etc.)

Which option is more expensive?

A tiny house is typically cheaper to build than a granny flat - but price alone doesn’t tell the whole story. You can expect to build a tiny house for between $30,000 and $60,000. In contrast, the average price of a new granny flat falls between $120,000 and $150,000.

Both a granny flat and a tiny house can help create an extra stream of income through rent (and with Sydney’s crowded property market this is an exciting advantage to either option).

However, the smaller floor space of a tiny house (39m2 or less) means a less inviting space whether it’s for you or as a stream of rental income. In contrast, a granny flat (60m2 to 90m2) can pose a more enticing space for singles, working professionals, or even small families to rent.

This makes the initial higher costs of a granny flat worth it to many Sydney homeowners who are looking to make an investment in their unused backyard space. Keep in mind, a granny flat can also help add value to your home so if you decide to sell, you’ll have more options on auction day.

What is the council planning difference?

Building an extra living space is exciting whether it’s a stylish granny flat or a contemporary tiny home. However, there are differences in the planning and paperwork required.

Most noticeably, there are no council requirements when building a tiny house - as long as it is mobile. You can add a tiny house anywhere on your property regardless of property size or street frontage. This is because tiny homes are classified as caravans.

In contrast, a granny flat is a fixed building on a fixed foundation. As a result, you are subject to certain council regulations. DA planning fees and council levies may apply so you will need more of a planning process to design and construct a granny flat on your Sydney property.

If your Sydney property is larger than 450m2 and has a minimum of 12m of street frontage, you may be exempt from council regulations, so speak to a member of the Bellcast Granny Flats team to find out more about your specific Sydney council rules.
