Granny Flats Above Garages


It is possible to build a 2-storey granny flat. In fact, it is a great idea, as you can have;


  • A double garage on the ground floor.
  • Your allowed living area on the granny flat above it.


This offers you a lot more space, as upstairs you can even have a balcony. The regulations are generally that the granny flat can be built above the garage, as long as:





  • The higher the building gets, setbacks increase to compensate for its’ height.


They’re applied once your building exceeds 3.8m. They depend on your block size and the height of the building. These setback are explained here. I suggest you contact your local council to determine your specific requirements as well.


Examples of ‘above garage’ designs are shown below:








Best Way to Build a Garage into a Home


Building the garage at the front line of your house creates depth. Just ensure the materials, windows, and any features you use match with your main home.


This will further the aesthetic appeal of your home. Adding a garage can also add to the style you are trying to achieve.


For example Up-lighting and down-lighting near your garage door can help add to the ‘Hampton’s style’ image.

Your garage door will give your home a different feel. If you like a more classic, country, retro feel, carriage house style doors are popular. If you prefer a more modern image, a steel garage door gives a sleek look.


To ensure it matches the over-all look of your home, see “Garage Door Ideas” below. Change the Hardware – A small change that can make a big impact.


The hardware on the garage door can make a big difference to the aesthetic appeal.


For example, if you have opted for a carriage house style door, these look great with;


  • An antique wrought iron dark hinge.
  • Hammered knockers.These add to that retro, country vibe.
  • Utilise Landscaping – Landscaping can be used to de-emphasise or highlight certain aspects of the garage door.
  • Brightly coloured plants do a great job of making a dull colour look more appealing.


The plants can be placed on the side of the garage or between the doors. You could add a pergola with a vine above the garage. This is a good option if you are going for a romantic, dreamy vibe.

Change Your Colour – Changing the colour of the garage door is an easy way to accentuate or downplay the door. Think wisely when choosing the colour. If you have a beautiful door you want to be the centre of attention, choose a lighter shade.


If you choose a darker shade, this enables some restraint. A bolder colour will add style to a house that is not yet overly decorated.


Add Windows


Adding windows to the garage door will add a lot of style. Windows can portray what looks like a loft or a second floor, which are common in Hampton’s houses. To achieve this, add a window above the garage and pair it with up-lighting.


Garage Door Ideas


The next thing you need to contemplate is what material to use on the garage door. A mistake many people make is thinking of the garage door as something not included in their original plan. Instead, you should think of it as one of the main components of your granny flat.


It is important, as the garage is a big piece of what people see when they look at your home. Everything must fit together perfectly so it adds to your homes visual appeal. So, think about what material your granny flat is made from and then what will match that;


Brick + Steel


Steel is a good choice because you won’t have to worry about maintenance. It’s also one of the least expensive materials. Steel is thick and has foam insulation, which will help you control the temperature and noise level in your garage.


Render + Wood


If you are a fan of a natural finish, then wood might be for you. Wood is strong but requires a lot of upkeep if you live in a humid, rainy area. Moisture will cause warping and rotting. You’ll need to paint and stain your wood garage door every few years.


It can be quite expensive, but good looks aren’t easy. You’ll need to be prepared to spend time and money maintaining the wood.


Cladding + Aluminium


Aluminium is a sturdier option than wood but not so much as steel. It is a good material for a garage door as it is lightweight. This makes double doors doable.




A little-known fact is that a garage as part of your granny flat is classified as a non-habitable space. This means that it will not be counted as part of your allowed living area. So, you can add a fully enclosed garage (or carport) to your granny flat without losing any space.


A granny flat can actually be a 2-storey building, so it can be built on top of a garage. There are limits regarding the height it can be built – the maximum height is 8.5m.


Although, once the building exceeds 3.8m in height, further regulations apply. Rear and side setbacks increase to counteract for its’ height. These vary, depending, amongst other things, the rules set by your council and the size of your block.


I suggest you contact your local council to find out their regulations and how this affects you. It’s important that your garage door fits the look of your home. Your garage exterior makes a huge difference to the appeal of your home.


Adding some features to your garage door can increase your overall style.
