There are many countries and further many states and cities which have a legal height for the ceilings marked and coded in their law. Any house with normally height less than 7 feet is illegal. So, for builders, it is very necessary to follow this law and build houses appropriately.
Many people think when the workers and laborers get the exact measurement of the walls and floors and ceilings, it is a tedious and small task. But these measurements are the key points of any building construction.
The handymen normally do this job of measurements, and if it is taken lightly or any mistake has been made in the measurements, it will cost a fortune for the homeowners to fix, especially the ceiling.
Although, in Australia, handymen will never have any trouble measuring the ceiling height as the legal height is already stated in the Australian Building Code.
Many people in Australia, Queensland, make rooms in the space under their houses. And as much as it is very good to use up space, it also should fall under the strict rules of height. The question becomes, what is the legal ceiling height in Queensland?
According to the Australian Building Codes, the ceiling height from the floor, in any habitable room should be 2.4 meters. And for non-habitable rooms, the average ceiling height is 2.1 meters.
Now comes the fact which rooms are habitable and which aren’t. This also is mentioned in the Australian Building Code.
Habitable rooms: The habitable rooms or places in a house are normally where people do activities and stay in for the most period of time. The kitchen, living room, bedroom, dining room, playroom, and entertainment room fall under this category.
Non-Habitable rooms: Bathrooms, hallways, corridors, garage, and pantry fall under this category as people do not spend most of the time in these places.
There is also the issue of the attic in modern houses. Many people would love to turn them into entertainment or bedrooms and such. But many houses have a sloping roof, so the rule states that specifically for the sloped roofs in the attic, the height should be 2.4 meters but only 50 – 60%.
Now, this was just for short or minimum heights. There is also a rule for maximum height limits in the Australian building codes.
For the high-ceiling houses, the roof or ceiling on average is 2.7 meters, but the homeowner is given the choice of around 2.5 meters to 3 meters.
Also, the houses which contain staircases or stairways, the only point to consider for stairs, is the headroom. They always maintain a minimum of 2 meters in height.
So, this rule is very important as otherwise the room is declared inhabitable and thus is named ‘utility room.’
