Research has shown that corridors, no matter how wide, can cause problems for a wide range of people with disabilities.
Minimising the use of corridors can make the house more flexible to more people. If corridors are unavoidable, consider providing wider areas in the corridor which can be used to give wheelchair access to the maximum number of spaces.
Having separate living and dining areas can provide more flexibility in how the house is used, particularly in larger houses.
If designing a home for people in wheelchairs, it important to understand how the occupants will use the space.
For example, while having a living room with enough space to turn a wheelchair my technically comply with the standard, it may not necessarily mean they can get out of the wheelchair and onto a chair or sofa. It is better to ensure that there is enough space for a wheelchair user to sit at the dining table in their chair, and to sit in their wheelchair to watch television.
It is not practical to assume that the occupants will push furniture (such as dining tables) out of the way to provide the necessary circulation space.
It is better design practice to show the furniture as it would be used, and to provide sufficient circulation space to get around it.
