10 Large Granny Flat Designs – Floorplans to Inspire
Before we get into the designs below; a common question I am asked about large granny flats is – can you build a granny flat over 60sqm?
The answer is yes, although it does depend upon your block size, the state/territory in which you live, and your Councils’ regulations. If you can comply with all of these, it is possible to build a granny flat up to as much as 100sqm.
Bigger granny flats can shock people with how imaginative they can look.

Today I will cover exactly when and where can you build these bigger granny flats. I will also talk about the benefits of building a granny flat that is bigger than 60sqm, then 80sqm, all the way right up to 100sqm.
Most people don’t realise you can expand the use of ‘livable’ space. Outdoor deck areas, do NOT count within your common 60sqm footprint. So with a little creative thought you can craft a bigger space to live within.
Granny Flat Designs Over 60sqm
60sqm is a common size for a granny flat. Why? Well, in some states in Australia, such as Victoria, SA, and Tasmania, this is the maximum size granny flat that your Council will allow you to build.
Though, it’s important to note that this does differ between Councils, so if you do live in one of these states, I do recommend that you contact yours for their regulations.
Starting with this design – You can even create a large one-bedroom granny flat with a large living/work from home space.
So then, what are the benefits of building a granny flat bigger than this, and where can you?
In WA, the maximum floor space is 70sqm – although, the Councils’ in rural areas are generally more flexible, and will allow you to build bigger than this.
Before thinking about expanding past 60sqm, consider increasing your ceiling height for a much bigger feel indoors.
In Queensland, you are allowed up to 80sqm. Though, to give you an example of how the regulations change between Councils, in Brisbane you are only allowed 70sqm, and only two bedrooms.
Again, I suggest that you speak to your local Council if you want to go above this floor space, as their regulations might be different than what will be approved by Complying Development.
The Northern Territory is quite strict – in the metropolitan area that is the city of Darwin, you are restricted to 50sqm. But in a rural area, your Council may be more lenient, allowing you up to 80sqm.
The added benefit of going over 60sqm, is that a design like this feels more like a larger house
If I have not yet mentioned your state, you are one of the lucky ones, as you will be allowed more than 80sqm, so look to one of the sub-heading below, and you will find yourself there.
Something you could consider changing is where the built-in wardrobes are in the two bedrooms at the top of the floor plan. If you move them, so they are instead backed-up against the combining wall, this would offer some soundproofing between these two bedrooms. The hallway already offers a great acoustic barrier between the third bedroom.
Multi-use spaces can be difficult to design, so you can also read architecturally designed spaces for inspiration, and hire an architect, who will help you to create a multi-use space that will work properly.
Now, if you are not planning on renting out your granny flat to students, another great design idea is to think about adding more spaces for storage.
Crafting better-use-of-space means storage doesn’t have to be a problem for larger granny flats
In a small space, utilising absolutely every single available spot that you can for storage is highly important. So, if there is enough room for any sort of cupboard, install one.
Just think about everything that you would take into a granny flat if you were moving into one, and that would need a space to be kept away.
When you start to think about it, there a quite a lot of things, and quite a lot of storage spaces you could build, such as:
For your books, build a bookshelf.
For your food, build a pantry and overhead cabinets.
For your utensils, build drawers and some more overhead cabinets.
For your cleaning products, build a cupboard. This may need to be big, as some of your equipment is large, such as your mop and bucket, and vacuum cleaner.
All your linen products, such as towels, bedsheets, spare pillows and blankets, and more, will need a linen cupboard.
In this day and age, most people have a collection of electrical goods, and their cords, for our smartphones and Bluetooth technology, which will need a cabinet of their own, and
Our heating and cooling appliances will also need a spot for storage.
Essentially, you need to keep all of these items off the floor and out of site. So, these storage spots will help your secondary dwelling feel much more spacious and free from clutter.
Another great option, if you have the available land space, is to extend your granny flat upwards. A loft is a lovely, calming area that can be used as another room (if the ceiling is at least 2.2m high), or simply for storage.
Council won’t deduct any of these areas from the maximum floor space you’re allowed, so you can add them without losing any of your internal floor space.
Open plan granny flats work well for both small and larger designs such as this one.
An example of a good design is Banksia (A) at Granny Flats Australia. The floor plan shows a porch, which can be extended further if you have the land space, and a one car garage that spans the entire width of the granny flat.
Parking the Bed in one corner of the granny flat means more room to use as you wish, especially in this huge studio design
Depending on your location and land size, it may be possible to build a granny flat bigger than 60sqm.
The benefits of doing so include using the space for:
More or bigger rooms, offering more privacy.
More storage, keeping things cleaner, or
More outdoor areas, for a better balance of indoor/outdoor living.
