What are the Housing Improvement Regulations 1947 and when would they apply?


The Housing Improvement Regulations 1947 (the Regulations) prescribe minimum standards for a bedroom.

There are some exceptions to the minimum standards in the Regulations (e.g. for bedrooms in modern residential apartments). Unless the exceptions apply, though, a bedroom must:

  • Have a minimum width of 1.8 metres;

  • Have an area of not less than 6 square metres;

  • Have a height from finished floor to finished ceiling of at least 2.1 metres in an existing house (as at 1975), or 2.4 metres in a new house;

  • Have at least one window situated in an external wall to admit adequate light;

  • The aggregate area of glass in the windows must not be less than one-tenth of the floor area of the room;

  • Windows with an area of not less than one-twentieth of the floor area must be able to be opened to allow air circulation, or in accordance with local authority requirements.


Can I advertise a property with a room as a “bedroom” if it meets the definition of bedroom from the Housing Improvement Regulations 1947, but it is not consented as a bedroom on the Council plans (e.g. the plans show that it is an office?)


No. Licensees must advertise in accordance with the Council plans. A room that is consented as an “office” should not be advertised as a “bedroom”.
