Adaptable design allow people to stay in their homes as they age. Designing for adaptability no longer means designing for people with disability or special need. Our society age continuously and as we age we may have a greater chances of developing limitations or disabilities that may require home modifications.
A person may not require a grabrails in bathroom at the age of 35 but designer should be aware that they may require that at a later stage and should provide a provision i.e. a support structure within the wall cavity when the bathroom is built.
