Minimum ceiling height

Hi all. We want to plaster our ceiling which has exposed beams. The house was built in 1976 and the floor to bottom of the beams is just under 2400. Does anyone know the minimum ceiling height requirements for a house built in 1976 in Victoria?

Thanks Ben

a room or space within a building must have sufficient height suitable for the intended function of that room or space. According to BCA Vol 2 part 3.8.2, for the requirement to be satisfied, the ceiling height must not be less than:

* in a habitable room excluding a kitchen - 2.4 m
* in a kitchen, laundry or the like - 2.1m
* in a corridor or passageway or the like - 2.1m
* in a bathroom, shower room, laundry, sanitary compartment, pantry, storeroom, garage, car parking area etc - 2.1m
* in an attic, room with a sloping ceiling or projection below ceiling line or non-habitable room or similar - a height that does not unduly interfere with the proper functioning of the room or space. More than 50% of the ceiling space should be on average a minimum height.
* in a stairway - 2.0m measured vertically above the nosing line.

Otherwise, the room would be deemed to be a "utility room".
