Signs are one of the last details to go on buildings and often an overlooked element in building design. Yet when they are installed appropriately, they can be the most helpful facility for visitors especially those with disabilities. A sign needs not be expensive to be useful. A simple tactile sign – (see photo) a raised profile of a female icon in red colour contrasting with the grey background, is very helpful to individuals with visual impairment to distinguish between male and female lavatories, and to avoid potential embarrassment of going into the wrong place.
