What is the Standard Ceiling Height in Australia?

It is important to get the right measurements when building a house. This is due to its huge impact on all future actions of the contractors.

One of its known impacts is forcing the handyman to re-do every work that has been done. This type of re-do can be very expensive for the homeowner, especially if there is a mistake on the ceiling.

Fortunately, handymen will never have a problem getting the right measurement for the ceiling because the standard ceiling height is clearly stated in the Australian Building Code.

According to the Building Code, the minimum ceiling height is 2.4 metres for habitable rooms. For non-habitable rooms, the standard ceiling height starts at 2.1 metres.

The habitable rooms are the areas of the house that are occupied by people to do various activities. The rooms they cover are the living room, bedroom, kitchen, and dining room. While the non-habitable rooms cover the bathroom/toilet, hallway, garage, and pantry.

Though this is the implemented standard ceiling height in Australia, there are areas of the house with additional conditions to be followed before determining the ceiling height. Two of the most common rooms/areas are the attic space and stairways.

Attics are typically left untouched by homeowners. But in modern home designs, homeowners have turned it into a habitable room—either a bedroom or an entertainment area. For this conversion, 50% to 60% of the attic must maintain the normal ceiling height in Australia, which is 2.4 metres.

Important Note: This is only applicable for attics with a sloping roof.

For houses with stairways, the only condition that the contractor or homeowner needs to consider is the headroom. They must always maintain a minimum of 2 metres in height.

What is the Average Ceiling Height in Australia to Maintain for High Ceiling Homes?

It is certain that more homeowners prefer to have higher ceilings. The obvious reasons are due to its elegant and luxurious appeal. However, it is also helpful in houses built in hotter climates because it makes it easier to cool the building.

Therefore, the average height of ceiling in Australia to follow is 2.7 metres. However, homeowners can have ceiling height options from 2.55 metres up to 3 metres.
