A bedroom is a private habitable space with in a dwelling for personal use, storage and rest. Bedrooms require an access door, windows providing sufficient ventilation and natural light. Electrical fittings and smoke alarms are also required to meet the requirements of a bedroom.
Standard bedroom sizes
There is no official minimum size for a bedroom, however adequate size is needed to fit a bed and perform personal activities. The master bedrooms usually consist of a walk in wardrobe and attached bathroom or ensuite. The 3rd or 4th bedroom in a house tends to be the smallest and can often be used as the office or study.
- Master bed – 3.5m x 3.5m
- bed two & three – 3.0m x 3.0m
- bed 4 – 2.8m x 2.8m
- Master bed – 3.8m x 4.0m
- bed two & three – 3.2m x 3.2m
- bed 4 – 3.0m x 3.0m
If any bedroom has dimensions of 2.7m or less it is extreme tight for a double bed and egress can become difficult. A room of this size is not practical and should not be considered anything more than a kids, baby’s room or an office. If the rooms are small and labelled ‘bedroom’ this will frustrate and deter tenants, possibly affecting your rental return.
A Bedroom does not require a wardrobe to be considered a bedroom. Wardrobes are expected in newer homes, but are commonly missing in older established homes. All bedrooms should have built in or walk in wardrobes. (refer to Wardrobes for further details).
Design and Layout
Take note of the door position into a bedroom. The best position for a door is to be recessed into a corner ideally next to the wardrobe. This maximises the rooms egress and does not inflict with furniture layout. If the door is positioned in the middle of the room it can compromised the usable space and the rooms function can dramatically be reduced.
When reviewing a rooms layout imagine all the possible furniture arrangements including, desks, dressing and bedside tables positions. As a rule a 700mm minimum should be left to allow comfortable egress between spaces. Window sizes and positions are also key to a rooms layout. Window sizes and placements can effect the layout and positioning of furniture in a room. If there is limited space ensure window sill heights are high enough allowing furniture to be placed underneath (refer to windows for further details). Ensure the positioning of the bed and bedside tables do not affect egress and the opening of doors. The electrical layout should also reflect furniture layouts (refer to electrical for further details).
A bedroom must have natural ventilation and light to in order to comply with Building Code of Australia. The BCA states that a bedroom must have windows that are equal in size to at least 10% of the rooms floor area and ventilation only 5%.
According to BCA Vol 2 part 3.8.2, the minimum ceiling height of a bedroom must be no less than 2.4m (refer to Layout & design for more info)
Those ugly Smoke alarms that are stuck to your ceiling must also comply with AS 3786. It is law that they are to be fitted to all bedrooms as per the Building Code of Australia 18.104.22.168.
Generally bedrooms are located on southern and western sides of a dwelling as a well designed home will always prioritise the main living areas to capture the northern aspect.
Often the master bedroom can be separate from the remaining bedrooms or divided by the main bathroom or living room. This segregation provides a little more privacy to the master bedroom instead of having kids room at your door stop.
The remaining bedrooms are usually clustered together and within close proximity of the bathroom facilities. Avoid having bedrooms scattered throughout the house and having to pass through main living areas to access these facilities. This is a sign of poor design and reduces privacy.
