There should be space for turning a wheelchair in dining areas and sitting rooms, and adequate circulation space for wheelchair users elsewhere.
The living room should be at entrance level.
In houses of two or more storeys, there should be space on the entrance level that could be used as a convenient bed-space.
The entrance level bed-space can be used as a temporary measure, and is particularly useful if a person has a temporary impairment.
At least one entrance level room will generally have this capacity. All that is generally required is careful thought about the siting of switches and sockets.
